Most other architectures are divided into a 32-bit and a 64-bit base tune.. so
it ends up something like:

mips/arch-mips.inc:
define: mips mipsel mips-nf mipsel-nf

mips/arch-mips64.inc:
include mips/arch-mips.inc

define: mips64-n32 mips64 mips64el-n32 mips64el mips64-nf-n32 mips64-nf
mips64el-nf-n32 mips64el-nf

tune-mips32r2.inc:
include mips/arch-mips.inc

define: (mips32r2 extensions)

tune-mips64r2.inc:
include mips/arch-mips64.inc

define: (mips64r2 extensions)


but if I remember right, there was a problem.  The 64-bit people wanted to use
the 32r2 version.  So if the include becomes:

include tune-mips32r2.inc (which includes arch-mips.inc)
include mips/arch-mips64.inc (which includes arch-mips.inc)

and now you run into the same thing being included two -- which you are not
supposed to do in OE..  So I believe this is why they were merged into a single
'arch-mips'.

The arch should define a basic set of tunes that work on all mips architectures
(within reason)

As long as the tunes remain, I'm fine.. but changing which files the base ones
are in can break BSPs developed elsewhere.  This is the biggest concern I have.
