config SMP
	bool

	help
	  This option is used to enable certain functions to make coreboot
	  work correctly on symmetric multi processor (SMP) systems.

config AP_SIPI_VECTOR
	hex
	default 0xfffff000
	help
	  This must equal address of ap_sipi_vector from bootblock build.

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
	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.
