config ARCH_AUTCPU12
bool "AUTCPU12"
help
Say Y if you intend to run the kernel on the autronix autcpu12
board. This board is based on a Cirrus Logic CS89712.
config ARCH_CDB89712
bool "CDB89712"
help
This is an evaluation board from Cirrus for the CS89712 processor.
The board includes 2 serial ports, Ethernet, IRDA, and expansion
headers. It comes with 16 MB SDRAM and 8 MB flash ROM.
config ARCH_CLEP7312

help
Boards based on the Cirrus Logic 7212/7312 chips.

help
Say Y here if you intend to run this kernel on a Cirrus Logic EDB-7211
evaluation board.
config ARCH_P720T

help
Say Y here if you intend to run this kernel on the ARM Prospector
720T.
config ARCH_FORTUNET
bool "FORTUNET"
config EP72XX_ROM_BOOT
bool "EP721x/EP731x ROM boot"
help
If you say Y here, your CLPS711x-based kernel will use the bootstrap
mode memory map instead of the normal memory map.
Processors derived from the Cirrus CLPS711X core support two boot
modes. Normal mode boots from the external memory device at CS0.
Bootstrap mode rearranges parts of the memory map, placing an
internal 128 byte bootstrap ROM at CS0. This option performs the
address map changes required to support booting in this mode.
You almost surely want to say N here.
