d1a5286099 usb: ehci-mx6: add support for otg port
Previously, only host1 was supported using an index of 0.
Now, otg has index 0, host1 is 1, host2 is 2, host3 is 3.
Since OTG requires usbmode to be set after reset, I added
CONFIG_EHCI_HCD_INIT_AFTER_RESET to nitrogen6x.h and
mx6qsabreauto.h.

I also added a weak function board_ehci_power to handle
turning power on/off for otg.

Type is type of device connected (USB stick vs Host.)
Init is type of device desired.
Only power up port if type == init == USB_INIT_HOST.
Only return error if type != init.

- Stream protocol hasn't been supported yet.

OMAP5 boards may have both eMMC (on MMC2) and an SD slot (on MMC1).  We
Update the default bootcmd to match what happens on AM335x where we try
SD first, and then eMMC.  In this case however, the hardware layout used
for powering both of these means that in the kernel eMMC shall be found
first as it is powered by a fixed regulator and SD found second as SD is
powered via the palmas which will result in deferred probing.

40462e541d mtd: driver _read() returns max_bitflips; mtd_read() returns -EUCLEAN
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:

  UBI DBG: ensure_wear_leveling: schedule scrubbing

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.

31cd065df0 Revert "am335x_evm.h: If mmcdev and bootpart switch to mmcdev 1, so should mmcroot."
Upon further inspection and review and chatting with kernel folks, what
happens here is that what mmcblk# a device gets is based on probe order.
So a system with an SD card inserted with place eMMC on mmcblk1, but
without an SD card, it will be on mmcblk0.  So U-boot can only provide a
best guess.  In this case, if no SD card is present, we would want to
pass mmcblk0p2 still.  If an SD card is present, it woudl be able to
provide a uEnv.txt that would be loaded (even if the kernel is NOT
there) which can still update mmcroot variable.

This reverts commit 827512fb11.

b770e88a6c Fix number base handling of "load" command
As documented, almost all U-Boot commands expect numbers to be entered
in hexadecimal input format. (Exception: for historical reasons, the
"sleep" command takes its argument in decimal input format.)

This rule was broken for the "load" command; for details please see
especially commits 045fa1e "fs: add filesystem switch libary,
implement ls and fsload commands" and 3f83c87 "fs: fix number base
behaviour change in fatload/ext*load".  In the result, the load
command would always require an explicit "0x" prefix for regular
(i. e. base 16 formatted) input.

Change this to use the standard notation of base 16 input format.
While strictly speaking this is a change of the user interface, we
hope that it will not cause trouble.  Stephen Warren comments (see
[1]):

        I suppose you can change the behaviour if you want; anyone
        writing "0x..." for their values presumably won't be
        affected, and if people really do assume all values in U-Boot
        are in hex, presumably nobody currently relies upon using
        non-prefixed values with the generic load command, since it
        doesn't work like that right now.

004f15b600 sf: Add memory mapped read support
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.
