CONFIG_EP72XX_ROM_BOOT
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 CLPS-711X 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.

CONFIG_ARCH_ARCA5K
This selects what ARM system you wish to build the kernel for. It
also selects to some extent the CPU type. If you are unsure what
to set this option to, please consult any information supplied with
your system.
CONFIG_ARCH_A5K
Say Y here to to support the Acorn A5000. Linux can support the
internal IDE disk and CD-ROM interface, serial and parallel port,
and the floppy drive. Note that on some A5000s the floppy is
plugged into the wrong socket on the motherboard.
CONFIG_ARCH_ARC
The Acorn Archimedes was an personal computer based on an 8K ARM2
processor, released in 1987. It supported 512K of RAM and 2 800K
floppy disks. Picture and more detailed specifications at
<http://www.computingmuseum.com/museum/archi.htm>.
CONFIG_PAGESIZE_16
Say Y here if your Archimedes or A5000 system has only 2MB of
memory, otherwise say N. The resulting kernel will not run on a
machine with 4MB of memory.

CONFIG_ARCH_AUTCPU12
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
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_CEIVA
Say Y here if you intend to run this kernel on the Ceiva/Polaroid
PhotoMax Digital Picture Frame.
CONFIG_ARCH_EDB7211
Say Y here if you intend to run this kernel on a Cirrus Logic EDB-7211
evaluation board.
CONFIG_ARCH_P720T
Say Y here if you intend to run this kernel on the ARM Prospector
720T.
CONFIG_EP72XX_ROM_BOOT
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 CLPS-711X 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.
