Linux commit 9c2af1c7377a8a6ef86e5cabf80978f3dbbb25c0
If Make gets a fatal signal while a shell is executing, it may delete
the target file that the recipe was supposed to update. This is needed
to make sure that it is remade from scratch when Make is next run; if
Make is interrupted after the recipe has begun to write the target file,
it results in an incomplete file whose time stamp is newer than that
of the prerequisites files. Make automatically deletes the incomplete
file on interrupt unless the target is marked .PRECIOUS.
The situation is just the same as when the shell fails for some reasons.
Usually when a recipe line fails, if it has changed the target file at
all, the file is corrupted, or at least it is not completely updated.
Yet the file’s time stamp says that it is now up to date, so the next
time Make runs, it will not try to update that file.
However, Make does not cater to delete the incomplete target file in
this case. We need to add .DELETE_ON_ERROR somewhere in the Makefile
to request it.
scripts/Kbuild.include seems a suitable place to add it because it is
included from almost all sub-makes.

Multiple people have reported intermittent build failure in parallel
building.
Kever Yang reported this issue some time ago [1], but I could not
get enough clue at that time.
This time, Richard Purdie provided a full build log [2], which was
very helpful for me to root-cause it.
The cause of the problem is commit 0d982c5853 ("Makefile: add
dependencies to regenerate u-boot.cfg when lost").
That commit added the 'cfg' as the prerequisite of the 'all' target,
so the parallel build tries to run it simultaneously, then regenerates
a symlink while building objects.
When u-boot.cfg is accidentally lost, let's rebuild it before
descending into any subdirectories.
Also, what is annoying is u-boot.cfg is currently regenerated every
time since it depends on FORCE. We can get rid of all the prerequisites
of u-boot.cfg because u-boot.cfg is rebuilt anyway as the byproduct of
auto.conf when a user updates the .config file.

If _debug_uart_putc() is called before _debug_uart_init(), the
ns16550 debug uart driver hangs in a tight loop waiting for the
tx FIFO to get empty.
As this can happen via a printf sneaking in before the port calls
debug_uart_init(), introduce a config option to ignore characters
before the debug uart is initialized.
This is done by reading the baudrate divisor and aborting if is zero.
The Kconfig option is required as reading the baudrate divisor does
not seem to work for all ns16500 compatibles (which is why the last
attempt on this has been reverted in 1a67969a99).
Tested on socfpga_cyclone5_socrates.

Commit 2c77c0d652 ("xyz-modem: Change getc timeout loop waiting")
fixes the loop delay when using a hw watchdog, assuming that watchdog
kicking is taken care of by getc(). But the xyzmodem driver tries to
do a getc only after confirming that a character is available like below:
while (!tstc()) {
till timeout;
}
if (tstc())
*c = getc();
and getc() does a watchdog reset only if it fails to see a character.
In this case, getc() always sees a character and never does a
watchdog reset. So to make sure that watchdog doesn't get reset
while loading the file, do a watchdog reset just before starting the
image loading.

Add support for gunzip-ing gzip-compressed uImages in the SPL Ymodem code.
Loading data over Ymodem can be gruelingly slow, gzip-ing the data can
reduce that aggravating slowness at least slightly (depends on the data,
u-boot.bin compresses to ~1/3 of it's original size on ARM64), hence add
optional support for decompressing gzip-compressed uImages.

The mmc_select_mode_and_width() function can be called while the card
is in HS200/HS400 mode and can be used to downgrade the card to lower
mode, e.g. HS. This is used for example by mmc_boot_part_access_chk()
which cannot access the card in HS200/HS400 mode and which is in turn
called by saveenv if env is in the MMC.
In such case, forcing the card clock to legacy frequency cannot work.
Instead, the card must be switched to HS mode first, from which it can
then be reprogrammed as needed.
However, this procedure needs additional code changes, since the current
implementation checks whether the card correctly switched to HS mode in
mmc_set_card_speed(). The check only expects that the card will be going
to HS mode from lower modes, not from higher modes, hence add a parameter
which indicates that the HS200/HS400 to HS downgrade is happening. This
makes the code send the switch command first, reconfigure the controller
next and finally perform the EXT_CSD readback check. The last two steps
cannot be done in reverse order as the card is already in HS mode when
the clock are being switched on the controller side.
