- Adding more and more optional and non-optional parameters bloated cbfstool and made the code hard to read with a lot of parsing in the actual cbfs handling functions. This change switches over to use getopt style options for everything but command and cbfs file name. - This allows us to simplify the coreboot Makefiles a bit - Also, add guards to include files - Fix some 80+ character lines - Add more detailed error reporting - Free memory we're allocating Signed-off-by: Stefan Reinauer <reinauer@google.com> Change-Id: Ia9137942deb8d26bbb30068e6de72466afe9b0a7 Reviewed-on: http://review.coreboot.org/1800 Tested-by: build bot (Jenkins) Reviewed-by: Ronald G.
