[U-Boot] Seperating MIPS processors

[Aaron Williams]

Hi,

One thing that I have had to do in our Octeon port of U-Boot is to seperate 
out the MIPS processors under /arch/mips/cpu much like has been done for ARM 
and PowerPC.

I have no way of testing the other MIPS platforms, but I've seperated things 
out as follows:

arch/mips/cpu/au1x00
arch/mips/cpu/incaip
arch/mips/cpu/mips32
arch/mips/cpu/octeon
arch/mips/cpu/purple

All of the code that's common between various 32-bit mips processors I put 
under mips32 with only the processor specific files in the appropriate 
directories.  Is this how I should do it?

Right now I can't really use any of the other MIPS files for our Octeon 
processor. There's just too many differences for this to make sense.

I basically have the following directory structure:

arch/mips/cpu/au1x00/au1x00_eth.c
arch/mips/cpu/au1x00/au1x00_serial.c
arch/mips/cpu/au1x00/au1x00_usb_ohci.c

While it might be quite a while until I can get our stuff into the mainline, 
it would certainly make things easier for me not to have to place our stuff in 
the same directory as the other processors.
