My concern is that while it's good and important we're correcting the
dependencies for ARM, non-ARMv7 hardware is much more legacy than new
design and we maybe don't want to have it enabled by default there. One
of the biggest pieces of feedback I have gotten over the overall EFI
support is that it being on by default on legacy systems causes a lot of
unwanted size growth. Does Kconfig work sanely with something like:
default y if !ARM
default y if ARM && (SYS_CPU = armv7 || SYS_CPU == arv8)
? Then we could allow other older ARM systems to enable it still and
now function (again, good work) without the size growth by default.
Thanks!
