# Assimilate MrChromebox coreboot distro, adapting its ports
|
||||
# for use in the Libreboot build system. This will create a
|
||||
# *patch* file for Libreboot, from the current lbmk commit.
|
||||
# Import MrChromebox project into xbmk
|
||||
|
||||
# These functions are used with the "./mk mrchromebox" command.
|
||||
# MrChromebox has a habit of using branches per project, each
|
||||
# branch being a given release. He does his changes on top of
|
||||
# upstream and goes from there.
|
||||
|
||||
# The coreboot build system (upstream one) already integrates
|
||||
# MrChromebox edk2 quite heavily, so Mrchromebox's own project
|
||||
# doesn't need a complicated external build system like lbmk.
|
||||
# He relies on pre-baked configs, that he provides, and uses
|
||||
# these to build the machines.
|
||||
# NOTE: variable naming scheme:
|
||||
# mr_ for variables/functions dealing with MrChromebox
|
||||
# mx_ for variables/functions pertaining to Libreboot setup
|
