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 ARCH_A5K
bool "A5000"
depends on ARCH_ARCA5K
help
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 PAGESIZE_16
bool "2MB physical memory"
depends on ARCH_ARCA5K
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.

* Requirement:
* We need to be able to allocate naturally aligned memory of finer
* granularity than the page size. This is typically used for the
* second level page tables on 32-bit ARMs.
*
* Theory:
* We "misuse" the Linux memory management system. We use alloc_page
* to allocate a page and then mark it as reserved. The Linux memory
* management system will then ignore the "offset", "next_hash" and
* "pprev_hash" entries in the mem_map for this page.
*
* We then use a bitstring in the "offset" field to mark which segments
* of the page are in use, and manipulate this as required during the
* allocation and freeing of these small pages.
*
* We also maintain a queue of pages being used for this purpose using
* the "next_hash" and "pprev_hash" entries of mem_map;
