New Revision: 1492
URL: http://flashrom.org/trac/flashrom/changeset/1492
Log:
Support compilation for the ARM architecture (little-endian only).
Note: The internal programmer will abort during processor check. This is
intentional.
The other hardware drivers (except those using port I/O) should work.
