My concern is that while it's goodk 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!
These are the only ARM11 boards:
evb-ast2500_defconfig
flea3_defconfig
integratorcp_cm1136_defconfig
mx31pdk_defconfig
mx35pdk_defconfig
rpi_0_w_defconfig
rpi_defconfig
woodburn_defconfig
woodburn_sd_defconfig
Which one poses a problem?
Best regards
Heinrich
