commit c65489f0b556a1e57adade6da8fdbcc06e5deeab Author: Vikram Narayanan vikram186@gmail.com Date: Sat Apr 14 15:25:13 2012 +0530
nvramtool: Unify nvramtool and build_opt_tbl
As cmos.layout parsing capabilities are already there in nvramtool, use those than using build_opt_tbl.c. Add binary and header file generation in nvramtool. Make appropriate changes to Makefile.inc.
