help
Say Y to support the Acorn Archimedes.
The Acorn Archimedes was an personal computer based on an 8MHz ARM2
processor, released in 1987. It supported up to 16MB of RAM in
later models and floppy, harddisc, ethernet etc.
config ARCH_A5K
bool "A5000"
select ARCH_MAY_HAVE_PC_FDC
help
Say Y here 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 PAGESIZE_16
bool "2MB physical memory (broken)"
help
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 ZBOOT_ROM
bool "Compressed boot loader in ROM/flash"
help
Say Y here if you intend to execute your compressed kernel image (zImage)
directly from ROM or flash. If unsure, say N.
config ZBOOT_ROM_TEXT
depends on ZBOOT_ROM
hex "Compressed ROM boot loader base address"
default "0"
help
The base address for zImage. Unless you have special requirements, you
should not change this value.
config ZBOOT_ROM_BSS
depends on ZBOOT_ROM
hex "Compressed ROM boot loader BSS address"
default "0"
help
The base address of 64KiB of read/write memory, which must be available
while the decompressor is running. Unless you have special requirements,
you should not change this value.
config XIP_KERNEL
bool "Execute In Place (XIP) kernel image"
help
Select this option to create a kernel that can be programmed into
the OS ROMs.
comment "At least one math emulation must be selected"
config FPE_NWFPE
tristate "NWFPE math emulation"
---help---
Say Y to include the NWFPE floating point emulator in the kernel.
This is necessary to run most binaries. Linux does not currently
support floating point hardware so you need to say Y here even if
your machine has an FPA or floating point co-processor module.
It is also possible to say M to build the emulator as a module
(nwfpe) or indeed to leave it out altogether. However, unless you
know what you are doing this can easily render your machine
unbootable. Saying Y is the safe option.
You may say N here if you are going to load the Acorn FPEmulator
early in the bootup.
source "fs/Kconfig.binfmt"
config PREEMPT
bool "Preemptible Kernel (EXPERIMENTAL)"
depends on CPU_32 && EXPERIMENTAL
help
This option reduces the latency of the kernel when reacting to
real-time or interactive events by allowing a low priority process to
be preempted even if it is in kernel mode executing a system call.
This allows applications to run more reliably even when the system is
under load.
Say Y here if you are building a kernel for a desktop, embedded
or real-time system. Say N if you are unsure.
config ARTHUR
tristate "RISC OS personality"
depends on CPU_32
help
Say Y here to include the kernel code necessary if you want to run
Acorn RISC OS/Arthur binaries under Linux. This code is still very
experimental; if this sounds frightening, say N and sleep in peace.
You can also say M here to compile this support as a module (which
will be called arthur).
config CMDLINE
string "Default kernel command string"
default ""
help
On some architectures (EBSA110 and CATS), there is currently no way
for the boot loader to pass arguments to the kernel. For these
architectures, you should supply some command-line options at build
time by entering them here. As a minimum, you should specify the
memory size and the root device (e.g., mem=64M root=/dev/nfs).
