More information on the Maverick EP9312 at . Say Y if you want support for the ARM920T processor. Otherwise, say N. # ARM926T config CPU_ARM926T bool select CPU_32v5 help This is a variant of the ARM920. It has slightly different instruction sequences for cache and TLB operations. Curiously, there is no documentation on it at the ARM corporate website. Say Y if you want support for the ARM926T processor. Otherwise, say N. # ARM946E-S config CPU_ARM946E bool select CPU_32v4T help ARM946E-S is a member of the ARM9E-S family of high- performance, 32-bit system-on-chip processor solutions. The TCM and ARMv5TE 32-bit instruction set is supported. Say Y if you want support for the ARM946E-S processor. Otherwise, say N. # Feroceon config CPU_FEROCEON bool select CPU_32v5 help This is a Marvell implementation of an ARMv5TE compatible ARM core, used in the Marvell Kirkwood SoC family. # ARMv6 config CPU_V6 bool select CPU_32v6 # ARMv7 config CPU_V7 bool select CPU_32v7 # ARMv8 config CPU_V8 bool select CPU_64v8 select CPU_SUPPORTS_64BIT_KERNEL select ARM_EXCEPTIONS config CPU_XSC3 bool select CPU_32v4T help Select code specific to PXA3xx variants # Xscale PXA25x, PXA27x config CPU_XSCALE bool select CPU_32v4T # Figure out what processor architecture version we should be using. # This defines the compiler instruction set which depends on the machine type. config CPU_32v4T bool select CPU_32 config CPU_32v5 bool select CPU_32 config CPU_32v6 bool select CPU_32 config CPU_32v7 bool select CPU_32 config CPU_64v8 bool select CPU_64 comment "processor features" config ARCH_SUPPORTS_BIG_ENDIAN bool config CPU_BIG_ENDIAN bool "Build big-endian kernel" depends on ARCH_SUPPORTS_BIG_ENDIAN help Say Y if you plan on running a kernel in big-endian mode. Note that your board must be properly built and your board port must properly enable any big-endian related features of your chipset/board/processor. config BOOT_ENDIANNESS_SWITCH bool "Support switching of Linux kernel endianness" help Say Y here if you need to switch CPU endianness before running Linux kernel, e.g. if you want big-endian Barebox to run little-endian Linux.
