Paul Kocialkowski 94b385fa23 usb: gadget: fastboot: Request status and length check in rx handler
This avoids handling requests that have an error status or no data.
In particular, this avoids showing unnecessary error messages when the USB
gadget gets disconnected (e.g. with fastboot continue) and the fastboot USB
gadget driver sends an error back to the host (that has disconnected already).

Weak versions of board_usb_init and board_usb_cleanup are defined in common USB
host code, but it is also used for USB device gadgets, so we also need a weak
definition of it when there is no USB host enabled.
Both weak definitions do not conflict.

Simon Glass fbeceb2602 dm: usb: Allow setting up a USB controller as a device/gadget
Some controllers support OTG (on-the-go) where they can operate as either
host or device. The gadget layer in U-Boot supports this.

While this layer does not interact with driver model, we can provide a
function which sets up the controller in the correct way. This way the code
at least builds (although it likely will not work).

Alexey Firago e2ec3e4612 fastboot: add support for reboot-bootloader command
The "fastboot reboot-bootloader" command is defined to
re-enter into fastboot mode after rebooting into
bootloader. This command is usually used after updating
bootloader via fastboot.

This commit implements only a generic side of the
command - setting of the reset flag and then resetting.
Setting of the reset flag is implemented using __weak
fb_set_reboot_flag() function. The actual setting and
checking of the reset flag should be implemented by
a boot script and/or board/SoC specific code.

By running dfu-util -e; one can force device to finish the execution of

Moreover, some naming has been changed - the dfu_reset() method now is known
as dfu_detach(). New name better reflects the purpose of the code.

It was also necessary to increase the number of usb_gadget_handle_interrupts()

CONFIG_SYS_DFU_DATA_BUF_SIZE may be large to allow for FAT/ext layouts
to transfer large files. However, this means that individual write
operations will take a long time. Allow backends to specify a maximum
buffer size, so that each write operation is limited to a smaller data
block. This prevents the DFU protocol from timing out when e.g. writing
to SPI flash. I would guess that NAND might benefit from setting this
value too, but I can't test that.

Stephen Warren 3ee9593fce dfu: add write error handling
Fix calls to dfu_write() and dfu_flush() to detect errors in the I/O
itself. This could happen due to problems with the storage medium, or
simply when trying to write a FAT/ext file that is larger than the buffer
dfu_mmc.c maintains for this purpose.

Signal the error by switching the DFU state/status. This will be picked
up by the DFU client when it sends the next DFU request. Note that errors
can't simply be returned from e.g. dnload_request_complete(), since that
function has no way to pass errors back to the DFU client; a call to
dnload_request_complete() simply means that a USB OUT completed.

This error state/status needs to be cleared when the next DFU client
connects. While there is a DFU_CLRSTATUS request, no DFU client seems to
send this. Hence, clear this when selecting the USB alternate setting on
the USB interface.

Finally, dfu.c relies on a call to dfu_flush() to clear up the internal
state of the write transaction. Now that errors in dfu_write() are
detected, dfu_flush() may no longer be called for every transaction.
Separate out the cleanup code into a new function, and call it whenever
dfu_write() fails, as well as from any call to dfu_flush().

Stephen Warren 7e54188775 usb: ci_udc: fix items array size/stride calculation
2 QTDs are allocated for each EP. The current allocation scheme aligns
the first QTD in each pair, but simply adds the struct size to calculate
the second QTD's address. This will result in a non-cache-aligned
addresss IF the system's ARCH_DMA_MINALIGN is not 32 bytes (i.e. the
size of struct ept_queue_item).

Similarly, the original ilist_ent_sz calculation aligned the value to
ARCH_DMA_MINALIGN but didn't take the USB HW's 32-byte alignment
requirement into account. This doesn't cause a practical issue unless
ARCH_DMA_MINALIGN < 32 (which I suspect is quite unlikely), but we may
as well fix the code to be explicit, so it's obviously completely
correct.

The new value of ILIST_ENT_SZ takes all alignment requirements into
account, so we can simplify ci_{flush,invalidate}_qtd() by simply using
that macro rather than calling roundup().

Similarly, the calculation of controller.items[i] can be simplified,
since each QTD is evenly spaced at its individual alignment requirement,
rather than each pair being aligned, and entries within the pair being
spaced apart only by structure size.

ci_udc.c's usb_gadget_unregister_driver() doesn't call driver->unbind()
unlike other USB gadget drivers. Fix it to do this.

Without this, when ether.c's CDC Ethernet device is torn down,
eth_unbind() is never called, so dev->gadget is never set to NULL.
For some reason, usb_eth_halt() is called both at the end of the first
use of the Ethernet device, and prior to any subsequent use. Since
dev->gadget is never cleared, all calls to usb_eth_halt() attempt to
stop, disconnect, and clean up the device, resulting in double cleanup,
which hangs U-Boot on my Tegra device at least.

ci_udc allocates its own singleton EP0 request object, and cleans it up
during usb_gadget_unregister_driver(). This appears necessary when using
the USB gadget framework in U-Boot, since that does not allocate/free
the EP0 request. However, the CDC Ethernet driver *does* allocate and
free its own EP0 requests. Consequently, we must protect
ci_ep_free_request() against double-freeing the request.

Stephen Warren 006c702688 usb: ci_udc: complete ep0 direction handling
handle_setup() currently assumes that the response to a Setup transaction
will be an OUT transaction, and any subsequent packet (if any) will be an
IN transaction. This appears to be valid in many cases; both USB
enumeration and Mass Storage work OK with this restriction. However, DFU
uses ep0 to transfer data in both directions. This renders the assumption
invalid; when sending data from device to host, the Data Stage is an IN
transaction, and the Status Stage is an OUT transaction. Enhance
handle_setup() to deduce the correct direction for the USB transactions
based on Setup transaction data.

ep0's request object only needs to be automatically re-queued when the
Data Stage completes, in order to implement the Status Stage. Once the
Status Stage transaction is complete, there is no need to re-queue the
USB request, so don't do that.

Don't sent USB request completion callbacks for Status Stage transactions.
These were queued by ci_udc itself, and only serve to confuse the USB
function code. For example, f_dfu attempts to interpret the 0-length data
buffers for Status Stage transactions as DFU packets. These buffers
contain stale data from the previous transaction. This causes f_dfu to
complain about a sequence number mismatch.

Allocate ep0's USB request object when the UDC driver is probed. This
solves a couple of issues in the current code:

a) A request object always exists for ep0. Prior to this patch, if setup
transactions arrived in an unexpected order, handle_setup() would need
to reply to a setup transaction before any ep0 usb_req was created.

This issue was introduced in commit 2813006fec "usb: ci_udc: allow
multiple buffer allocs per ep."

b) handle_ep_complete no longer /has/ to queue the ep0 request again
after every single request completion. This is currently required, since
handle_setup() assumes it can find some request object in ep0's request
queue. This patch doesn't actually stop handle_ep_complete() from always
requeueing the request, but the next patch will.

Stephen Warren 2813006fec usb: ci_udc: allow multiple buffer allocs per ep
Modify ci_ep_alloc_request() to return a dynamically allocated request
object, rather than a singleton that's part of the endpoint. This
requires moving various state from the endpoint structure to the request
structure, since we need one copy per request.

The "fast bounce buffer" b_fast is removed by this change rather than
moved to the request object. Instead, we enhance the bounce buffer logic
in ci_bounce()/ci_debounce() to keep the bounce buffer around between
request submissions. This avoids the need to allocate an arbitrarily-
sized bounce buffer up-front, yet avoids incurring the allocation
overhead each time a request is submitted.

A future enhancement would be to actually submit multiple requests to HW
at once. The Linux driver shows that this is possible. That might improve
throughput (depending on the USB protocol in use), since USB could be
performing a transfer to one HW buffer in parallel with whatever SW
actions U-Boot performs on another buffer. However, I have not made this
change as part of this patch, in order to keep SW changes related to
buffer management separate from any change in the way the HW is
programmed.

Stephen Warren 25fbf96b24 USB: gadget: save driver name before registering it
g_dnl_register() currently first attempts to register a composite
driver by name, and then saves the driver name once it's registered.
Internally to the registration code, g_dnl_do_config() is called and
attempts to compare the composite device's name with the list of known
device names. This fails since the composite device's name has not yet
been stored. This means that the first time "ums 0 0" is run, it fails,
but subsequent attempts succeed.

Re-order the name-saving and registration code to solve this.

Mateusz Zalega 75504e9592 usb: dfu: fix boards wo USB cable detection
Former usb_cable_connected() patch broke compilation of boards which do
not support this feature.

I've renamed usb_cable_connected() to g_dnl_usb_cable_connected() and added
its default implementation to gadget downloader driver code. There's
only one driver of this kind and it's unlikely there'll be another, so
there's no point in keeping it in /common.

Previously this function was declared in usb.h. I've moved it, since
it's more appropriate to keep it in g_dnl.h - usb.h seems to be intended
for USB host implementation.

Existing code, confronted with default -EOPNOTSUPP return value,
continues as if the cable was connected.

CONFIG_USB_CABLE_CHECK was removed.

Allow ci_udc.o to be built when using the new(?) USB gadget framework,
as enabled by CONFIG_USB_GADGET.

Note that this duplicates the Makefile entry for ci_udc.o, since it's
also included inside #ifdef CONFIG_USB_ETHER. I'm not sure what that
define means; perhaps an old style of Ethernet-specific USB gadget
implementation?

I wonder if the line that this patch adds shouldn't be outside all of

is shared between the two?

Stephen Warren a022c1e13c usb: ums: use only 1 buffer for CI_UDC
ci_udc.c allocates only a single buffer for each endpoint, which
ci_ep_alloc_request() returns as a hard-coded value rather than
dynamically allocating. Consequently, storage_common.c must limit
itself to using a single buffer at a time. Add a special case
to the definition of FSG_NUM_BUFFERS for this.

Another option would be to fix ci_ep_alloc_request() to dynamically
allocate the buffers like some/all(?) other device mode drivers do.
However, I don't think that ci_ep_queue() supports queueing up
multiple buffers either yet, and I'm not familiar enough with the
controller yet to implement that. As such, any attempt to use multiple
buffers simply results in data corruption and other errors.

Stephen Warren fcf2ede190 usb: ci_udc: support variants with hostpc register
Tegra's USB controller appears to be a variant of the ChipIdea
controller; perhaps derived from it, or simply a different version of
the IP core to what U-Boot supports today.

In this variant, at least the following difference are present:
- Some registers are moved about.
- Setup transaction completion is reported in a separate 'epsetupstat'
  register, rather than in 'epstat' (which still exists, perhaps for
  other transaction types).
- USB connection speed is reported in a separate 'hostpc1_devlc'
  register, rather than 'portsc'.
- The registers used by ci_udc.c begin at offset 0x130 from the USB
  register base, rather than offset 0x140. However, this is handled
  by the associated EHCI controller driver, since the register address
  is stored in controller.ctrl->hcor.

Introduce define CONFIG_CI_UDC_HAS_HOSTPC to indicate which variant of
the controller should be supported. The "HAS_HOSTPC" part of this name
mirrors the similar "has_hostpc" field used by the Linux EHCI controller
core to represent the presence/absence of the hostpc1_devlc register.

Stephen Warren 0c51dc6db9 usb: ci_udc: make PHY initialization conditional
usb_gadget_register_driver() currently unconditionally programs PORTSC
to select a ULPI PHY. This is incorrect on at least the Tegra boards I
am testing with, which use a UTMI PHY for the OTG ports. Make the PHY
selection code conditional upon the specific EHCI controller that is in
use.

Ideally, I believe that the PHY initialization code should be part of
ehci_hcd_init() in the relevant EHCI controller driver, or some board-
specific function that ehci_hcd_init() calls.

For MX6, I'm not sure this PHY initialization code is correct even before
this patch, since ehci-mx6's ehci_hcd_init() already configures PORTSC to
a board-specific value, and it seems likely that the code in ci_udc.c is
incorrectly undoing this. Perhaps this is not an issue if the PHY
selection register bits aren't implemented on this instance of the MX6
USB controller?

ehci-mxs.c doens't appear to touch PORTSC, so this code is likely still
required there.

Stephen Warren 8aac6e9c53 usb: ci_udc: set ep->req.actual after transfer
At least drivers/usb/gadget/storage_common.c expects that ep->req.actual
contain the number of bytes actually transferred. (At least in practice,
I observed it failing to work correctly unless this was the case).

However, ci_udc.c modifies ep->req.length instead. I assume that .length
 is supposed to represent the allocated buffer size, whereas .actual is
supposed to represent the actual number of bytes transferred. In the OUT
transaction case, this may happen simply because the host sends a smaller
 packet than the max possible size, which is quite legal. In the IN case,
transferring fewer bytes than requested could presumably happen as an
error.

Modify handle_ep_complete() to write to .actual rather than modifying
.length.

Fix this by initializing all 5 pageN pointers, which allows up to

Heiko Schocher 001a831986 usb: dfu: introduce dfuMANIFEST state
on nand flash using ubi, after the download of the new image into
the flash, the "rest" of the nand sectors get erased while flushing
the medium. With current u-boot version dfu-util may show:

Starting download: [##################################################] finished!
state(7) = dfuMANIFEST, status(0) = No error condition is present
unable to read DFU status

as get_status is not answered while erasing sectors, if erasing
needs some time.

So do the following changes to prevent this:

- introduce dfuManifest state
  According to dfu specification
  ( http://www.usb.org/developers/devclass_docs/usbdfu10.pdf ) section 7:
  "the device enters the dfuMANIFEST-SYNC state and awaits the solicitation
   of the status report by the host. Upon receipt of the anticipated
   DFU_GETSTATUS, the device enters the dfuMANIFEST state, where it
   completes its reprogramming operations."

- when stepping into dfuManifest state, sending a PollTimeout
  DFU_MANIFEST_POLL_TIMEOUT in ms, to the host, so the host
  (dfu-util) waits the PollTimeout before sending a get_status again.

Lukasz Majewski e0059eaef1 usb:udc:samsung: Zero copy approach for data passed to Samsung's UDC driver
The Samsung's UDC driver is not anymore copying data from USB requests to
aligned internal buffers. Now it works directly in data allocated in the
upper layers like UMS, DFU, THOR.

This change is possible since those gadgets now must take care to allocate
buffers aligned to cache line (CONFIG_SYS_CACHELINE_SIZE).

This can be achieved by using DEFINE_CACHE_ALIGN_BUFFER() or
ALLOC_CACHE_ALIGN_BUFFER() macros. Those take care to allocate buffer
aligned to cache line in both starting address and its size.
Sometimes it is enough to just use memalign() with size being a
multiplication of cache line size.

Lukasz Majewski 716662bd19 usb:udc:samsung: Remove redundant cache operation from Samsung UDC driver
A set of cache operations (both invalidation and flush) were redundant
in the S3C HS OTG Samsung driver:

1. s3c_udc_ep0_zlp - to transmit EP0's ZLP packets one don't need to flush
the cache (since it is the zero length transmission)

2. s3c_udc_pre_setup and s3c_ep0_complete_out - cache invalidation is not
needed when the buffer for OUT EP0 transmission is setup, since no data
has yet arrived.

Cache cleanups presented above don't contribute much to transmission speed
up, hence shall be regarded as cosmetic changes.

3. setdma_rx - here the s3c UDC driver's internal buffers were invalidated.
This call is not needed anymore since we reuse the buffers passed from
gadgets. This is a key contribution to transmission speed improvement.

The fifo size of ep0 is 64 bytes, and if the packet size grater than
64 bytes, the driver would have to fill up the fifo multiple times,
and before filling up the fifo, the driver should make sure the fifo
is empty by checking fifo empty indication.

However there is a hardware bug that the fifo empty indication is
somehow a bit earlier than fifo reset. So if I don't add an extra
delay here, the data might be corrupted. (i.e., 1 byte missing)

After a couple of tests, it truns out that 1 usec is good enough.

Troy Kisky 43880ce5be usb: gadget: ether set wMaxPacketSize
set wMaxPacketSize for full speed descriptors
fs_source_desc, fs_sink_desc to 64.

Full-speed bulk endpoint can have a maximum packet size of
8, 16, 32, or 64 bytes, so choice 64.

The hs_source_desc, hs_sink_desc, already have their wMaxPacketSize
set to 512. That is the only legal value for high speed bulk endpoints.

Strictly speaking, this patch is not needed because
usb_ep_autoconfig will call ep_matches which will
override wMaxPacketSize for BULK endpoints only with
the size associated with the endpoint setup by the udc driver.
But if you want to rely on this, you may as well combine the
full speed descriptor with the high speed descriptor to
minimize confusion.
