Here is a little patch to optimize swab operations by using "wsbh"
instruction available on mips revision 2 cpus. I do not know what

Comments ?
Looks good aside of the one issue you've already raised yourself:
+/* FIXME: MIPS_R2 only */
I was actually asking for advices :)
I can see only two simple ways to do that:
(a) we can define a couple of new macro ie CONFIG_MIPS32_ISET_R[12]
that can be set depending on the selected CPU;
(b) define a new macro CONFIG_CPU_HAS_WSBH;
Don't we already have CONFIG_CPU_MIPS32R2?
