This option is used to enable certain functions to make coreboot
work correctly on symmetric multi processor (SMP) systems.
-# Set MMX and SSE in socket or model if the CPU has them.
-# If all CPUs for the socket have MMX or SSE, set them there.
-# These options are only needed for boards compiled with romcc.
config MMX
bool
+ help
+ Select MMX in your socket or model Kconfig if your CPU has MMX
+ streaming SIMD instructions. 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
+ 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.
