command: commands: Add macros to declare commands with subcmds
Most cmd/xxx.c source files expose several commands through a single

kbuild: add .SECONDARY special target to scripts/Kbuild.include
Based on the following Linux commits:
- 54a702f70589 ("kbuild: mark $(targets) as .SECONDARY and remove
.PRECIOUS markers")
- 8e9b61b293d9 ("kbuild: move .SECONDARY special target to
Kbuild.include")
GNU Make automatically deletes intermediate files that are updated
in a chain of pattern rules.
Example 1) %.dtb.o <- %.dtb.S <- %.dtb <- %.dts
Example 2) %.o <- %.c <- %.c_shipped
A couple of makefiles mark such targets as .PRECIOUS to prevent Make
from deleting them, but the correct way is to use .SECONDARY.
.SECONDARY
Prerequisites of this special target are treated as intermediate
files but are never automatically deleted.
.PRECIOUS
When make is interrupted during execution, it may delete the target
file it is updating if the file was modified since make started.
If you mark the file as precious, make will never delete the file
if interrupted.
Both can avoid deletion of intermediate files, but the difference is
the behavior when Make is interrupted; .SECONDARY deletes the target,
but .PRECIOUS does not.
The use of .PRECIOUS is relatively rare since we do not want to keep
partially constructed (possibly corrupted) targets.
.SECONDARY with no prerequisites causes all targets to be treated as
secondary. This agrees the policy of Kbuild.
scripts/Kbuild.include seems a suitable place to add it because it is
included from almost all sub-makes.
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.

kbuild: fix parallel build race caused by u-boot.cfg regeneration
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 0d982c585330 ("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.
serial: ns16550: fix debug uart putc called before init
If _debug_uart_putc() is called before _debug_uart_init(), the

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

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.

2. The device downloads its MLO/SPL via UART (not eMMC - the eMMC pinmux
pins are NOT probed/configured in MLO/SPL).
3. The loaded via UART MLO/SPL wants to load Linux from eMMC. In this case
the DM core and pinctrl uclass checks 'u-boot,dm-spl' and don't
