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.

Some Exynos boards, such as the SMDK5250, control USB port power through
a GPIO pin. For now this had been hardcoded in the exynos5-dt board
file, but not all boards use the same pin, requiring local changes to
support different boards.
This patch moves the GPIO initialization into the USB host controller
drivers which they belong to, and uses the samsung,vbus-gpio parameter
in the device tree to configure it.

Linux modified the MTD driver interface in commit edbc4540 (with the
same name as this commit). The effect is that calls to mtd_read will
not return -EUCLEAN if the number of ECC-corrected bit errors is below
a certain threshold, which defaults to the strength of the ECC. This
allows -EUCLEAN to stop indicating "some bits were corrected" and begin
indicating "a large number of bits were corrected, the data held in
this region of flash may be lost soon". UBI makes use of this and when
-EUCLEAN is returned from mtd_read it will move data to another block
of flash. Without adopting this interface change UBI on U-boot attempts
to move data between blocks every time a single bit is corrected using
the ECC, which is a very common occurance on some devices.
For some devices where bit errors are common enough, UBI can get stuck
constantly moving data around because each block it attempts to use has
a single bit error. This condition is hit when wear_leveling_worker
attempts to move data from one PEB to another in response to an
-EUCLEAN/UBI_IO_BITFLIPS error. When this happens ubi_eba_copy_leb is
called to perform the data copy, and after the data is written it is
read back to check its validity. If that read returns UBI_IO_BITFLIPS
(in response to an MTD -EUCLEAN) then ubi_eba_copy_leb returns 1 to
wear_leveling worker, which then proceeds to schedule the destination
PEB for erasure. This leads to erase_worker running on the PEB, and
following a successful erase wear_leveling_worker is called which
begins this whole cycle all over again. The end result is that (without
UBI debug output enabled) the boot appears to simply hang whilst in
reality U-boot busily works away at destroying a block of the NAND
flash. Debug output from this situation:

This patch adopts the interface change as in Linux commit edbc4540 in
order to avoid such situations. Given that none of the drivers under
drivers/mtd return -EUCLEAN, this should only affect those using
software ECC. I have tested that it works on a board which is
currently out of tree, but which I hope to be able to begin
upstreaming soon.

Since SPI register access is so expensive, it is worth transferring data
a word at a time if we can. This complicates the driver unfortunately.
Use the byte-swapping feature to avoid having to convert to/from big
endian in software.

Accessing SPI registers is slow, but access to the FIFO level register
in particular seems to be extraordinarily expensive (I measure up to
600ns). Perhaps it is required to synchronise with the SPI byte output
logic which might run at 1/8th of the 40MHz SPI speed (just a guess).
Reduce access to this register by filling up and emptying FIFOs
more completely, rather than just one word each time around the inner
loop.
Since the rxfifo value will now likely be much greater that what we read
before we fill the txfifo, we only fill the txfifo halfway. This is
because if the txfifo is empty, but the rxfifo has data in it, then writing
too much data to the txfifo may overflow the rxfifo as data arrives.
This speeds up SPI flash reading from about 1MB/s to about 2MB/s on snow.

Qspi controller can have a memory mapped port which can be used for
data read. Added support to enable memory mapped port read.
This patch enables the following:
- It enables exchange of memory map address between mtd and qspi
through the introduction of "memory_map" flag.
- Add support to communicate to the driver that memory mapped
transfer is to be started through introduction of new flags like
"SPI_XFER_MEM_MAP" and "SPI_XFER_MEM_MAP_END".
This will enable the spi controller to do memory mapped configurations
if required.
