The (upstream) changes to break up SYS_MALLOC_F_LEN for the full
U-Boot and the SPL stage, break TPL (if simple malloc is enabled in
TPL).
This adds support for a TPL-variant of SYS_MALLOC_F_LEN:
- adds TPL_SYS_MALLOC_F_LEN
- rewrites a test for CONFIG_SPL_SYS_MALLOC_F_LEN to access
CONFIG_VAL(SYS_MALLOC_F_LEN)
Signed-off-by: Philipp Tomsich <philipp.toms...@theobroma-systems.com>
Version-changes: 3
- (new patch) adds changes to SYS_MALLOC_F_LEN for TPL to fix breakage
from rebasing to u-boot-rockchip/master
