* Add support for the Lenovo ThinkPad T420 and X220.
* Fix the autodetection of ifdtool and me_cleaner.
* Enable FBWhiptail mode for X220 and T420
* Decreased CBFS size to fix 50 seconds boot delay problems
Add ability to change CMOS values by genning SMBIOS tables and using the values from stock bios, this allows for editing of SMBIOS values to change things such as VRAM allocation, FN and CTRL key swap etc
Disabling IOMMU on the iGPU for Heads (mostly) eliminates
display corruption when kexec'ing to new kernel (and has no effect
on iGPU/IOMMU for kexec'ed kernel)

Drop coreinto/memtest secondary payloads as they are not
usable with Linux as primary payload. Leftover copy-pasta
from original SeaBIOS configs.

Remove debug symbols and dynamic debug support from Linux. This reduces
our resulting bzImage by 100K.
This should help when size becomes even more limited, see #562
This changes Heads' bootscript for the x230 to gui-init and adds config
options needed for it. The config is very similar to the librem13v2 config.
My comparison of startup-time from a power-button press shows 2.5 seconds
more with these changes applied.
That said, the experience is smooth, the GUI is beautiful and easier to use
than the shell and text menu, especially during setup. That's what we
buy with startup time here.
The Librem coreboot is labeled with the current version and is visible
from dmidecode and is supposed to reflect the current version of
coreboot, however it was out of date and reflected 4.7 when Heads has
moved on to 4.8.1.
I've also added a simple change to further simplify onboarding by
warning users who have Librem Key configured when they boot without it
being inserted.
This reduces the amount of noise in the Linux kernel config files
by only storing the differences from the stock configuration.
It adds a new makefile target 'linux.saveconfig' to convert the
build tree's .config file into config/linux-linuxboot.config.
Adding the VBT file makes it available through some ACPI memory area
and apparently the VBT contains the information needed by the i915 driver
in order to figure out how to control the screen's backlight.
Without the VBT, we can't control the screen backlight with Fn-F5/Fn-F6
anymore.
Fixes access to the EC through the Index I/O interface
Fixes AC and DC LoadLine values to avoid overheating problems
Fix Turbo mode value from EC
Change version name to have '-heads' suffix
By enabling Pass-through iommu, it fixes the GPU glitching issues
we've had with IOMMU, and it also allows us to boot a target kernel
without having to give it intel_iommu=igfx_off as argument.
Guarded linuxboot specific init entries
Removed Makefile entries into separate file (conflicts with srcing /etc/config)
Added CONFIG_BOOT_LOCAL/_REMOTE to control interface setup
Fixed CONFIG_TPM usage
USB smart card readers are most full speed devices, and there is no
"rate-matching hubs" beneath the root hub on older (e.g. GM45) plat-
forms, which has companion OHCI or UHCI controllers and needs cor-
responding drivers to communicate with card readers directly plugged
into the motherboard, otherwise a discrete USB hub should be inserted
between the motherboard and the reader.
This time I make inserting linux modules for OHCI and UHCI controllable
with option CONFIG_LINUX_USB_COMPANION_CONTROLLER.
A linux config for x200 is added as an example.
Tested on my x200s and elitebook revolve 810g1.
Move board configuration into `boards/` instead of `config/`
Fix mistake in building kernel module tree before kernel was done.
Allow per-board initrd builds (#278)
Allow per-board configurations for things (#304)
This modifies the `Makefile.nerf` to create files based on the
$(BOARD) variable, which is necessary as we start to support
multiple mainboards.
The config files must define five variables, all in bytes:
* `NERF_SIZE` - for the EFI firmware volume that contains Linux
* `PEI_SIZE` - size of the PEI image in the vendor ROM
* `PEI_OFFSET` - offset of the PEI image in the vendor ROM
* `ME_SIZE` - size of the ME image in the vendor ROM, or 0 if
there is no ME image to be extracted.
* `ME_OFFSET` - offset of the ME image in the vendor ROM
The `ifd.bin` must be created and can be checked in.
The default ROM input file is `blobs/$(BOARD)/$(BOARD).rom`,
and it *must not* be checked in.
This links in the AcpiTableDxe and AcpiPlatform executables from
the edk2 build tree and adds a depex dependency for the Linux
kernel on the AcpiTable being setup. The `acpi.cpio` file is
no longer included in the Linux kernel bzImage.
The `Makefile.nerf` has been re-written to generate the firmware
file system (FFS) files via rules.
TODO: figure out how to add LZMA compressed sections so that the
900k acpi tables can be compressed to about 100k.
This allows flashrom to work on the r630 NERF server, but
also increases the size of the flashrom executable significantly
since it brings in all chipset and flash types.
This development branch builds a NERF firmware for the Dell R630
server. It does not use coreboot; instead it branches directly
from the vendor's PEI core into Linux and the Heads runtime
that is setup to be run as an EFI executable.
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.
Similar to qubes-update, it will save then verify the hashes of
the kexec files. Once TOTP is verified, a normal boot will verify
that the file hashes and all the kexec params match and if
successful, boot directly to OS.
Also added a config option to require hash verification for
non-recovery boots, failing to recovery not met.
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/.
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
Replace libuuid with util-linux libuuid (and libblkid,
although we are not using libblkid right now).
This also requires a much larger coreboot cbfs, which was
fixed as part of issue #154.
