[U-Boot] [PATCH 3/3] linker: Modify linker scripts to be more generic

Tom Rini trini at konsulko.com
Tue Jan 22 22:09:26 UTC 2019


Make use of "IMAGE_MAX_SIZE" and "IMAGE_TEXT_BASE" rather than
CONFIG_SPL_MAX_SIZE and CONFIG_SPL_TEXT_BASE.  This lets us re-use the
same script for both SPL and TPL.  Add logic to scripts/Makefile.spl to
pass in the right value when preprocessing the script.
