# If set, the workarounds for these ARM errata are applied early during U-Boot
# startup. Note that in general these options force the workarounds to be
# applied; no CPU-type/version detection exists, unlike the similar options in
# the Linux kernel. Do not set these options unless they apply! Also note that
# the following can be machine specific errata. These do have ability to
# provide rudimentary version and machine specific checks, but expect no
# product checks:

In emulated environments, semihosting is a way for
the hosted environment to call out to the emulator to
retrieve files from the host machine.

If SoC does not support L2CACHE or one do not want to enable
L2CACHE, choose this option.

If the SoC's BOOT0 requires a header area filled with (magic)
values, then choose this option, and create a define called
ARM_SOC_BOOT0_HOOK which contains the required assembler
preprocessor code.
