[U-Boot] Sync ARM subsystem repos with the upstream

[Masahiro Yamada]

Hi.


Commit 2e07c249a67e055db294818ff063d502d15db0f8
(kconfig: arm: introduce symbol for ARM CPUs)
touched lots of ARM Kconfigs.

I recommend ARM SoC custodians synchronize
their repos with u-boot/master.
Otherwise, you may have to resolve conflicts lator.


Best Regards
