Dear Alex Ling,

This patch adds basic support for FriendlyARM MINI6410 development board (a Chinese clone of Samsung SMDK6410)
Please restrict your line length to < 70 characters.
General note: please rebase your code on top of Heiko's ARm rework patches (enable caches, add relocation). These will go in before your board support.

So does this make sense on your board? Please remove dead code.

This is probably NOT what you want to do.
