[U-Boot] [PATCH v2 1/2] m68k: add malloc memory for early malloc

Angelo Dureghello angelo at sysam.it
Sun Dec 20 16:54:35 CET 2015


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.
