ROMCC can build more efficient code if it can spill to MMX registers. config SSE bool help Select SSE in your socket or model Kconfig if your CPU has SSE streaming SIMD instructions. ROMCC can build more efficient code if it can spill to SSE (aka XMM) registers. config SSE2 bool default n help Select SSE2 in your socket or model Kconfig if your CPU has SSE2 streaming SIMD instructions. Some parts of coreboot can be built with more efficient code if SSE2 instructions are available. config VAR_MTRR_HOLE bool default y help Unset this if you don't want the MTRR code to use subtractive MTRRs
