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`

Use global /tmp/config that combines multiple config files As part of the config gui we want to be able to have the system define new config options without them being lost if the user makes their own changes in CBFS. To allow that this change creates a function initiated in init that combines all /etc/config* files into /tmp/config. All existing scripts have been changed to source /tmp/config instead of /etc/config. The config-gui.sh script now uses /etc/config.user to hold user configuration options but the combine_configs function will allow that to expand as others want to split configuration out further. As it stands here are the current config files: /etc/config -- Compiled-in configuration options /etc/config.user -- User preferences that override /etc/config /tmp/config -- Running config referenced by the BIOS, combination of existing configs 2018-12-06 23:24:28 +00:00			`. /tmp/config`

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`

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"`
