Update Heads to use the 4.9 Linux LTS kernel. No patches are required to boot 4.9 as a coreboot payload, unlike the 4.7 kernel that required a head_64.S patch. The new kernel is about 40 KB larger than the 4.7; the config might be shrinkable. Close issue #61. 2016-12-12 16:01:18 +00:00			`linux_version := 4.9`

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			`linux_config := linux.config`
