comment "Processor Type"
config CPU_32
bool
default y
# Select CPU types depending on the architecture selected. This selects
# which CPUs we support in the kernel image, and the compiler instruction
# optimiser behaviour.
# ARM1176
config CPU_ARM1176
bool
select CPU_V6
# ARM920T
config CPU_ARM920T
bool
select CPU_32v4T
help
The ARM920T is licensed to be produced by numerous vendors,
and is used in the Maverick EP9312 and the Samsung S3C2410.
More information on the Maverick EP9312 at
<http://www.cirrus.com/en/products/ep9312.html>.
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.

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.

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.
Currently implemented only by "bootz" command.
config ARCH_HAS_L2X0
bool
config CACHE_L2X0
bool "Enable L2x0 PrimeCell"
depends on MMU && ARCH_HAS_L2X0
