Librem13v2: Enable IOMMU and Pass-through mode
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.

baa30a2026 Add OHCI and UHCI drivers to initrd.
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.

Build multiple boards with the NERF firmware (issue #268)
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.

Attempt to use the edk2 ACPI tables (issue #266)
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.

non-recovery boots, failing to recovery not met.

kernel 4.9 setup with framebuffer for x230 (issue #64) 2016-12-13 14:58:23 -05:00

a6520772dc
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.

4fbd6ca58b
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.
