11 only select this option if you have hardware that actually has a
12 64-bit processor and if your application will actually benefit from
13 64-bit processing, otherwise say N. You must say Y for kernels for
14 SGI IP27 (Origin 200 and 2000) and SGI IP32 (O2). If in doubt say N.

602 These are evaluation boards built by AMD/Alchemy to
603 showcase their Au1X00 Internet Edge Processors. The SOC design
604 is based on the MIPS32 architecture running at 266/400/500MHz
