There are a few NAND commands that make the chip only respond on I/O
lines 0 to 7 even for x16 devices. READID (90h) is one such command
which was already handled fine in the driver (at least for NFC v1 and
v2). Other commands (like PARAM (ECh) to read out ONFI parameters)
however were not handled properly. Instead of adding another callback
make the read_byte callback handle the holes added by the NFC and depend
on the nand-base support to call read_byte when necessary instead of
read_buf.
This fixes reading the ONFI parameter page on an i.MX25 with an x16 NAND
and probably[1] also the result of READID on i.MX51/i.MX53 with x16
NAND.

The ecc code in omap_correct_data() expects to correct a whole page
at once, so we must tell the nand layer that we have 4 * 13 bytes of
ecc bytes and 4 * 512 bytes of ecc size. Otherwise the NAND layer will
iterate over 512 byte steps over a page and call the .correct callback
each time.
This only works for 2k pagesize and needs revisit once other page sizes
shall be supported. It would be better to tell the nand layer the real
ecc bytes (13) and ecc size (512) instead and drop the iteration in
omap_correct_bch(). However, this needs better testing so it isn't done
here now.

MIPS: dts: use physical addresses (as Linux does)
With IOMEM() adapted for MIPS we can use physical addresses
in device tree reg property.
has switched MIPS dts files to physical addresses usage.
The patch was tested on qemu, but qemu malta board is tolerant
of using physical addresses for accesing to device
(Ingenic JZ4755 and JZ4780 processors are tolerant too!).
But other CPUs (e.g. Loongson LS1B) can throw an exception
in this situation.
Additional physical address to virtual address translation
on MIPS is needed.
We already have this in include/common.h
#if defined(CONFIG_MIPS)
#include <asm/addrspace.h>
#define IOMEM(addr) ((void __force __iomem *)CKSEG1ADDR(addr))
#else
#define IOMEM(addr) ((void __force __iomem *)(addr))
#endif

As the SMC1111 has a shared pool of 2k memory buckets for both
transmission and reception, and as there are variants which have as few
as 4 buckets in total, the memory pool can be hogged by unclaimed
receptions, and impeed any further transmission.
This happens on the zylonite pxa board, where 4 packets, most probably
icmp and arp, fill the 4 buckets, preventing any further ethernet
transmission, and stalling the driver.
The fix is rather rough : whenever all the buckets are filled by
reception packets, and if a transmission is required, the transmission
code path will empty up all received packets.

ehci-hcd.c. Fix both.

This adds a buffer for log messages and a 'dmesg' command to
print the messages. The log buffer is implemented as log objects
rather than a string buffer. This makes it easy to implement
limiting the messages, cleaning the buffer and timestamping
the messages.

This changes the MUSB support from the original Kernel state to
be usable with barebox. Tested on a custom board and the Beaglebone
Black. The host port on the Beaglebone works, the OTG port works
in device mode, but not yet in host mode.
Based on the initial MUSB port from Rolf Evers Fischer.

Since the MUSB driver will have it's own directory the Kconfig
entries won't be in drivers/usb/gadget/Kconfig. This is incompatible
with the current 'choice' approach for udc drivers. The udc drivers
do not implement the global usb_gadget_poll() anymore, so we can
drop the choice and allow multiple gadget drivers.
Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
Instead of letting each driver implement usb_gadget_poll directly
implement this function in the core which then calls into the
drivers.

If the GEM is used, however only FE featuren enabled, then it can not
support FBLDO configured as 16, and no RGMII/GMII configuratin bit.
So, in order to support GEM only with FE feature enabled, we do:
- using default value for FBLDO.
- using same bit for RMII/MII configuration as GEM for RGMII/GMII.
