commit 9361e5572c4597a7e2509f17a79fd62370dd6caa Author: Kyösti Mälkki kyosti.malkki@gmail.com Date: Mon Mar 19 19:40:01 2012 +0200
Makefile: split romstage linking to separate rules
After change it is more clear how romstage is linked twice and with what scripts. Also with the change, it is easier to add some object of static size that need to be re-compiled for the 2nd link. One such object could be md5sum of executable.
