commit 2c49f4c908d30e66831b1edf5a81343371a50096 Author: Martin Roth martinroth@chromium.org Date: Tue Aug 30 16:21:53 2016 -0600
Kconfig: Add option for microcode filenames
Hardcoding the microcode filenames into the makefiles is great when the microcode is in the blobs directory. When the microcode isn't posted to the blobs directory, we need some method of supplying the microcode binary into the build. This can of course be done manually after the build has completed, as can be done with everything that we're including in the ROM image. Instead of making life hard for everyone though, let's just add a way to specify where the microcode rom comes from.
