Ugh! That shmobile name is going to haunt us forever (even though we 
don't even make SH-Mobile parts anymore....and they are all ARM cores now, 
not SH).

I will say that upstream in the kernel, most everything else has been 
renamed to "renesas" (ie, ARCH_RENESAS, )...except that directory name. I 
asked if/when they would rename it, but at the moment, there is not plan
as not to break anything.

Maybe we can compromise on everything in mach-renesas??
