- add a usbserial command to enable/disable the serial gadget
- allow dfu and usbserial to cohexist in the same barebox
- add a timeout in u_serial so that we don't get locked if the user
enable usbserial from a UART console but doesn't consume the data
on the usbserial port created on the PC
- remove debug or verbose printf
- tested on i.MX25 & i.MX35 & usb-a926x

- bwPollTimeout is set to 10 ms, from the DFU spec, this
is the minimum time, in milliseconds, that the host should
wait before sending a subsequent DFU_GETSTATUS request.
Without this, I get 25 seconds value and dfu-util waits twice 25s
during download
- when in IDLE and receiving DETACH, first return 0 to make
dfu-util happy, then use a dfudetach variable to exit dfu
(without an USB reset as per the comment on line 425) and
return to runtime mode.
- tested on i.MX25 & i.MX35 & usb-a926x

- this patch sync fsl_udc.c with linux's driver,
- add a poller on usb_gadget_poll to get serial gadget working,
- return -EIO in usb_gadget_poll when udc is stopped (do detect
cable disonnection)

from being compound devices, forbid use_acm=1 for PXAs.

This is needed for the ohci-at91 to work.
In u-boot this function was transmitting a cmdlen of 12, by the initial
commit. There are similar functions like usb_request_sense,
usb_read_capacity nearby which also transmit 12 byte per default on
u-boot, which probably also need a fix.

As USB can have its cable plugged out anytime, make the
serial gadget reliable in case of unplugging :
- unregister the gadget_serial provided console
- don't stay forever in the read loop if connection was cut
This behaviour relies on correct implementation of
usb_gadget_poll(), which should return an error if the USB
cable was removed.

The serial gadget can only work if the serial function is
properly connected on USB trigger (ie. on SET_CONFIGURATION
or SET_INTERFACE USB message triggering set_alt() in
composite.c).
Make this connection and handle also the disconnection in
f_serial.

Use the generic gadget polling function instead of the
specific fsl function. This is a fix from a leftover in

Implemented an initial version of USB mass storage device driver,
supporting USB mass storage devices with SCSI interface and BBB
protocol. It implements the ATA interface and registers diskovered
LUNs with the disk driver.
To allow for some generic io accessors introduce io.h and use
this instead of asm/io.h throughout the tree.

This patch makes the USB command optional and makes usb_rescan a
global function. This way we can use USB in noninteractive
environments.

The idea is to panic() when there is no memory available for normal
operation. Exception: code which can consume arbitrary amount of RAM
(example: files allocated in ramfs) must report error instead of panic().
This patch also fixes code which didn't check for NULL from malloc() etc.
Usage: malloc(), memalign() return NULL when out of RAM.
xmalloc(), xmemalign() always return non-NULL or panic().
