Subject: Move board_init_f_mem() into a common location
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=af6bbd4daefc314cc422381580f11fabc9cb222f;p=u-boot.git

Move board_init_f_mem() into a common location

This function will be used by both SPL and U-Boot proper. So move it into
a common place. Also change the #ifdef so that the early malloc() area is
not set up in SPL if CONFIG_SYS_SPL_MALLOC_START is defined. In that case
it would never actually be used, and just chews up stack space.
