[U-Boot] [PATCH v3 1/2] m68k: add malloc memory for early malloc
Angelo Dureghello

Mon Apr 25 00:20:04 CEST 2016
To use serial uclass and DM, CONFIG_SYS_MALLOC_F must be used.
So CONFIG_SYS_GENERIC_GLOBAL_DATA has been undefined and
call to board_init_f_mem() is added for all cpu's.
Signed-off-by: Angelo Dureghello <angelo at sysam.it>

Changes for v2:
- none
Changes for v3:
- fix start.S using new board_init_f_alloc_reserve
