[OpenWrt-Devel] [RFC] Mips SIMD architecture (MSA)

[José Vázquez]

As far i can understand MSA is a feature that is only present in the
MIPS Warrior cores and, for now, seems that could be only needed in
malta [1] target.
As you can see in arch/mips/Kconfig MIPS32R2 and MIPS64R2 select
CPU_SUPPORTS_MSA which does not apply to the majority of the mips
targets in OpenWRT.
Deleting "select CPU_SUPPORTS_MSA" in [2] and [3] and changing [4]
with "depends CPU_MIPS32_R2 || CPU_MIPS64_R2" will make MSA selectable
and should make the kernel smaller.
