Make coreboot building modular to support multiple boards. This touches most of the module configurations since the coreboot build process had to add a few new features. The Linux kernel could make use of it as well if we need separate x230/chell/qemu kernels, for instance. 2016-11-23 17:11:08 +00:00			`# Coreboot builds are specialized on a per-target basis.`

Rework Makefile a bit. rename TARGET to BOARD (fix #55) use .INTERMEDIATE trick to avoid building multiple times (fix #52) Don't touch build/*/.config if we don't have to (fix #51) 2016-11-29 16:19:48 +00:00			`#coreboot_config := coreboot-$(TARGET).config`
