FWIW it doesn't even seem to be the right reason either. AFACIT the 
issue being introduced is that SND_MMP_SOC_SSPA selects SND_ARM which 
depends on ARM, but after patch #8 ARCH_MMP itself will no longer 
necessarily imply ARM. The fact that selecting SND_ARM with unmet 
dependencies also allows SND_ARMAACI to be enabled (which appears to be 
the only thing actually containing open-coded Arm asm) is tangential.
