adds a USB boot option with basic parsing to kexec Supports booting from USB media using either the root device or a signed ISO as the boot device. Boot options are parsed with quick/dirty shell scripts to infer kexec params. Closes #195 and begins to address #196 2017-04-29 17:40:34 +00:00			`#!/bin/sh`
Added a generic boot config and persistent params Refactored boot parsing code and applied that in local-init to scan /boot for grub options and allow the user to unsafely boot anything. This goes a long way to addressing #196. Optionally the user can customize those boot parameters or enforce arbitrary hashes on the boot device by creating and signing config files in /boot/ or /media/ or /media/kexec_iso/ISO_FILENAME/. 2017-07-03 03:01:04 +00:00			`# Boot a USB installation`

Make TPM dependency optional and controlled by flag CONFIG_TPM if "CONFIG_TPM=y" is not present in the config file, functionalities needing TPM could be disabled, while leaving other functionalities intact. This will make Heads a more general-usage bootloader payload atop coreboot. 2017-12-05 08:29:07 +00:00			`if [ "$CONFIG_TPM" = "y" ]; then`

Minor tweaks to signing params and boot options Also split out usb-scan to allow manual initiation of scan from the recovery shell 2017-07-03 17:07:03 +00:00			`usb-scan`
Added rollback protection to generic boot Changed the checking of required hashes or required rollback state to be right before boot, allowing the user to sign/set defaults in interactive mode. Also cleaned up usages of recovery and fixed iso parameter regression. 2017-07-08 20:59:37 +00:00			`recovery "Something failed during USB boot"`
