This is probably a bike-shed issue that I should let slide...

But can someone explain to me: in what circumstances

plus_sec := $(call as-instr,.arch_extension sec,+sec)
AFLAGS_smc.o :=-Wa,-march=armv7-a$(plus_sec)

is preferable over

AFLAGS_smc.o := -Wa,-mcpu=cortex-a9

in a machine-specific Makefile?


Arnd mentioned consistency with other machines; ISTM that
simplicity and obviousness are also desirable characteristics.

Regards.
