common: command: Rework the 'cmd is repeatable' logic

The repeatable property is currently attached to the main command and
sub-commands have no way to change the repeatable value (the
->repeatable field in sub-command entries is ignored).

Replace the ->repeatable field by an extended ->cmd() hook (called
->cmd_rep()) which takes a new int pointer to store the repeatable cap
of the command being executed.

With this trick, we can let sub-commands decide whether they are
repeatable or not.

We also patch mmc and dtimg who are testing the ->repeatable field
directly (they now use cmd_is_repeatable() instead), and fix the help
entry manually since it doesn't use the U_BOOT_CMD() macro.

   .PRECIOUS markers")

 - 8e9b61b293d9 ("kbuild: move .SECONDARY special target to

GNU Make automatically deletes intermediate files that are updated

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.

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

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.

arm: Round the dma_alloc_coherent memory size to cache line aligned

When running usb dwc3 gadget driver, we meet random USB enumeration failure in fastboot.
The root cause is a cache coherence issue. When it happens, the ctrl_req in
gadget driver is allocated at 0xfe932f40, and the usb_composite_dev (cdev)
is allocated at 0xfe932f60. So after we submit the setup request (cache flushed) to USB
controller, any accessing to usb_composite_dev variable will cause the cache line refill, then
when setup transfer is completed, reading the setup data in ctrl_req will gets old value from
cache not from memory.

The ctrl_req is allocated by API dma_alloc_coherent, but u-boot don't have cohernet memory.
so it still needs cache maintain operations before/after HW accessing. Since the cache flush or
invalidate bases on cache line, so when the allocated memory size is not cache line aligned,
potentially it may meet such issue.

This patch modifies the dma_alloc_coherent API to round the size to cache line aligned.
