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()

parts, provide the total size of the image to the first write.part

subsequent parts of the volume. This results in a sequence of commands
akin to:

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:

This patch adopts the interface change as in Linux commit

order to avoid such situations. Given that none of the drivers under

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

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.

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.
