[U-Boot] [PATCH v2 1/2] blackfin: convert blackfin board_f and board_r to use generic board init functions
Sonic Zhang
sonic.adi at gmail.com
Wed Jul 30 08:16:15 CEST 2014
From: Sonic Zhang <sonic.zhang at analog.com>
- 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
