commit 6f25945813eb935b31a6f7886abd3ada9af90232 Author: Cristian Măgherușan-Stanciu cristi.magherusan@gmail.com Date: Sun Jun 19 03:03:28 2011 +0200
Add the coreboot config to CBFS
The CBFS will contain a new file, named 'config' of type 'raw' that is a stripped-down version of the .config file that was used to build the current coreboot image. For space savings, all the comments and empty lines were removed from the original config, except for one that lists the coreboot git revision that's built into the image.
This is done in order to easily reproduce the work of someone else when only having their ROM image. In theory the reproduce could even be automated by a new dedicated make target.
This should work even with abuild now.
