 Peter has the final word in things, and nobody objected anymore to introducing
BR2_GENIMAGE_CFG_FILES, so:

 Introduce BR2_GENIMAGE_CFG_FILES.

 select BR2_PACKAGE_HOST_GENIMAGE

 Note that since BR2_GENIMAGE_CFG_FILES is a string option, you can't do that
directly. You need to introduce a blind helper option:

config BR2_GENIMAGE_CFG_FILES_SELECT
	bool
	default y if BR2_GENIMAGE_CFG_FILES != ""
	select BR2_PACKAGE_HOST_GENIMAGE

 I think you can start converting more boards. But you can already stop before
all boards are converted.

 For each board you should verify that the build result with and without your
change is identical! To save build time, you may want to use an external
toolchain though...

 Arnout
