Two small improvements, but even without them this patch is OK for me.
- In arch/Config.in, the ARM section and the Blackfin section look the same to
the casual onlooker, but for ARM the MMU options depend on the subarchitecture,
while for Blackfin it's always NOMMU. So I'd make this explicit by adding a
comment for ARM:
bool "ARM (little endian)"
# MMU support is set by subarchitectur in Config.in.arm
Same for ELF in the second patch.
- Like you did for ARM, I think you should move the MMU selection to the
subarches for xtensa as well. Since in fact, the fsf variant is always MMU.
So if you repost this patch and make the above changes, you can add my Acked-by.
