Dear Vladimir Zapolskiy,

I'm willing to pick this into 2012.07. But I have some questions.

Isn't this dataflash stuff oriented by 1056 bytes page size?

NAK, This is wrong here cause:
 a) console_init_f() is intended to be run from flash but board_init is
    run after relocation (we may get issues here if maybe code that
    should only run before relocation is not relocated).
 b) it is called before from lib/board.c: board_init_f() in
    init_sequence

tab size is 8 char for indention, would be nice to have same space
