commit 051c9a902b107d04db832d7909172c6d33ded243 Author: Furquan Shaikh furquan@google.com Date: Tue Apr 22 16:33:22 2014 -0700
Move redundant Makefile rules from arch to top level.
Remove all the common Makefile rules like coreboot.pre, coreboot.pre1 and others from arch level Makefile.inc to top level Makefile.inc. Also, organize Makefile.inc at arch level into per-stage rules and variables.
