I'm not sure to understand how this option articulates with the
CPU_ENDIAN_BE8 option, because your other patch series ("Initial
big-endian support series") in its PATCH 4 ("ARM: set BE8 if LE in head
code") already switches the kernel into BE mode even if it's booted
from a Little Endian bootloader.
Maybe what you wanted to achieve is:
* The first patch series "Initial big-endian support series" allows to
run the kernel big-endian if the bootloader has booted it big-endian.
* The second patch series "ARM big-endian - atags and loader updates",
allows to run the kernel big-endian even if the bootloader started
In this case, then the PATCH 4 of your first patch series ("ARM: set
BE8 if LE in head code") should be in the second patch series, and
the code be conditional under CPU_BE8_BOOT_LE.
Or maybe I'm missing something?
