The ARM920T is licensed to be produced by numerous vendors,

and is used in the Maverick EP9312 and the Samsung S3C2410.

Say Y if you want support for the ARM920T processor.
|
|
|
|
Otherwise, say N.

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 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.

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.
