-gerrit commit 6555dcc1828a30615b98652cccd80f707550a7fe Author: Patrick Georgi <[email protected]> Date: Fri Mar 9 12:30:07 2012 +0100 Add preprocessing capabilities to the cbfs-files mechanism It's now possible to generate files that are about to be added to CBFS by specifying "sourcefile:method" as real file name. This makes the build system use the cbfs-files-preprocessor-$(method) function to create a file from sourcefile. That generated file is then added to CBFS. The first method to be defined is "nvramtool". It expects a plain text specification of the CMOS configuration and emits the binary format suitable for cmos.default.
