commit 39ac34473f3c96e77cbe03a49141771ed1639486 ("cmd_mtdparts: use 64
bits for flash size, partition size & offset") introduced warnings
in a couple places due to printf formats or pointer casting.This patch fixes the warnings pointed out here:

Pass a valid cmdtp into do_tftpb(), do_ext2load(), and do_get_fat(), to
avoid possible crashes due to null pointer dereferencing.Commit d7884e047d08447dfd1374e9fa2fdf7ab36e56f5 does not go far enough.
There is still at least one call chain that can result in a crash.The do_tftpb(), do_ext2load(), and do_get_fat() functions expect a valid
cmdtp. Passing in NULL is particularly bad in the do_tftpb() case,
because eventually boot_get_kernel() will be called with a NULL cmdtp:do_tftpb() -> netboot_common() -> bootm_maybe_autostart() -> do_bootm()
-> do_bootm_states() -> bootm_find_os() -> boot_get_kernel()Around line 991 in cmd_bootm.c, boot_get_kernel() will dereference the
null pointer, and the board will crash.Signed-off-by: Steven A. Falco

it shows warning information when reboot the system as following:*** Warning - bad CRC, using default environment

When a toolchain invocation fails, an exception is thrown but not caught
which then aborts the entire toolchain detection process. To solve this,
request that exceptions not be thrown, since the toolchain init code
already error-checks the command result. This solves e.g.:- found '/usr/bin/winegcc'
Traceback (most recent call last):
...

The musb driver defines and uses MUSB_CSR0_H_DIS_PING, however this
bit is reserved on the DM36x. Thus this patch ensures that the
reserved bit is not accesssed.It has been observed that some USB devices will fail to enumerate
with errors such as 'error in inquiry' without this patch.See http://www.ti.com/litv/pdf/sprufh9a for details.

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.Tested-by: Aparna Balasubramanian

This allows you to write data to an UBI volume when the amount of memory
available to write that data from is less than the total size of the
data. For example, you may split a root filesystem UBIFS image into
parts, provide the total size of the image to the first write.part
command and then use multiple write.part commands to write the
subsequent parts of the volume. This results in a sequence of commands
akin to:ext4load mmc 0:1 0x80000000 rootfs.ubifs.0
ubi write.part 0x80000000 root 0x08000000 0x18000000
ext4load mmc 0:1 0x80000000 rootfs.ubifs.1
ubi write.part 0x80000000 root 0x08000000
ext4load mmc 0:1 0x80000000 rootfs.ubifs.2
ubi write.part 0x80000000 root 0x08000000This would write 384MiB of data to the UBI volume 'root' whilst only
requiring 128MiB of said data to be held in memory at a time.Signed-off-by: Paul Burton

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.Signed-off-by: Paul Burton
