Subject: [U-Boot] [PATCH 1/2 v4] m68k: add malloc memory for early malloc
Date: Wed, 27 Apr 2016 21:50:44 +0200 [thread overview]
Message-ID: <1461786644-2275-1-git-send-email-angelo@sysam.it> (raw)
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@sysam.it>
---
Changes for v2:
- none
Changes for v3:
- fix start.S using new board_init_f_alloc_reserve
Changes for v4:
- fix start.S for correct passage of boot_args to board_init_f
