My 2c...

I have been working with the 6410 tree in several places.  A merge of samsung tree would be greatly appreciated.

Please remember that since I am working SmartQ and there are 3 other 6410 based MACHs in Ben's next-s3c tree.  

So, please, MACH_SMDK6410 != CPU_6410 and
            MACH_SMDK6410 != PLAT_64XX.

The common peripheral support needs to be factored out so that "thin" MACH configs can set some per-MACH GPIOs/chipsets (LCD, power,etc.)

Thanks
