- move blackfin specific cpu init code from blackfin board.c to cpu.c - remove blackfin specific board init code and invoke generic board_f fron cpu init entry - rename section name bss_vma to bss_start in order to match the generic board init code - add a fake relocate_code function to set up the new stack only Signed-off-by: Sonic Zhang <sonic.zhang@analog.com>
