-gerrit commit a442eafcfe6bd399a6eac61952170f763d45ac22 Author: Vikram Narayanan <[email protected]> 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.
