This is useful to reproduce a build after the fact or to check +whether support for a specific feature is enabled in the image. + +This file has been generated using the 'savedefconfig' Kconfig command, +which generates the minimal .config file that is needed to produce the +required config in a coreboot build. This is fine for reproduction, but +bad when you want to check if a certain config was enabled, since many +options get enabled by default or pulled in through another option's +'select' statement and thus don't show up in the defconfig. -### Add significant changes here +Instead coreboot now includes a larger .config instead. In order to save +some space, all of the comments disabling options are removed from the +file, except for those included in the defconfig. +We can also LZMA compress the file since it is never read by firmware +itself and only intended for later re-extraction via cbfstool, which +always has LZMA support included.
