Build time configuration for startup scripts and modules. This addresses multiple issues: * Issue #63: initrd is build fresh each time, so tracked files do not matter. * Issue #144: build time configuration * Issue #123: allows us to customize the startup experience * Issue #122: manual start-xen will go away * Issue #25: tpmtotp PCRs are updated after reading the secret * Issue #16: insmod now meaures modules 2017-03-31 15:18:46 +00:00			`modules-y += busybox`

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			`busybox_config := busybox.config`

Build initrd tools with musl-libc (issue #77). This adds compilations modules for musl-libc and kernel-headers. The entire initrd (busybox, cryptsetup, gpgv, kexec, etc) can be built with the much smaller libc and it appears to work with chroot. Library paths are not set correctly and files are installed into heads/install to make them accessible to other modules. This prevents the initrd from working without manual fixup; need to fix before merging into master. Build times have gone up since everything is being rebuilt more often for some reason. 2016-12-29 23:23:08 +00:00			`busybox_target := \`
