"blobs" repository

We provide a new repository for binary components and hooked it up in the build. So far it provides binaries for the Intel Sandybridge and Ivybridge platform, as well as the AMD Geode VSA binary that used to be distributed by Marc Jones.

The latter could be replaced by source in the main repository as soon as someone takes the time to port the VSA source (also part of the repository) from MASM assembly to some syntax compatible with our build system.

For VSA, the build system was slightly extended so its cbfs-files mechanism can be used to add coreboot stages.

Simplify using a driver for multiple PCI IDs

Instead of defining a device structure for a larger number of devices (eg. multiple revisions of the same device), extend them so they can optionally cover a set of devices.

static const struct pci_driver pch_sata_ahci_driver __pci_driver = {
   .ops    = &sata_ops,
   .vendor = PCI_VENDOR_ID_INTEL,
   .device = 0x1c02,
};
static const struct pci_driver pch_sata_mobile_ahci_driver __pci_driver = {
   .ops    = &sata_ops,
   .vendor = PCI_VENDOR_ID_INTEL,
   .device = 0x1c03,
};

becomes

static const struct pci_driver pch_sata_driver __pci_driver = {
    .ops    = &sata_ops,
    .vendor = PCI_VENDOR_ID_INTEL,
    .devices = { 0x1c02, 0x1c03 },
};

Fixed long time bug in Intel microcode update code

We used to have a couple of issues with cpuid in the past. It's an opcode that modifies a whole lot of registers, and we didn't always teach gcc about all of them.

The latest victim is Intel microcode updates - or rather, one of the earlier ones, since the code was broken since 2004. It only triggered bugs in later code if the compiler tried to reuse values in clobbered registers, and was rather elusive.

roda/rk886ex: Expose VGA devices

This one is interesting as it explains some of the less well documented properties in coreboot, devices in devicetree.cb:

As a rule of thumb, all devices should be listed (and not commented out) that are on-board. While coreboot can find them on its own, it only marks devices as "on mainboard" that are explicitely mentioned - among other things, the VGABIOS execution system uses that to determine the VGABIOS location, but we also run set_subsystem only on onboard hardware.

Preprocessor mangling

Some preprocessor idioms were unified. CONFIG_FOO==1 became CONFIG_FOO, CONFIG_FOO==0 became !CONFIG_FOO.

We also added the config_enabled macro recently introduced with Linux. It works both for the preprocessor and inside code, and will allow us to eventually reduce the amount of changes we carry around in our version of Kconfig.

Perl 6 == Forth?

“The idea with Perl 6 is you start with a standard language and you
can mutate it. As long as you follow that refinement process there
isn't the problem of ambiguity. There is the problem of multiple
dialects, but that will always be a problem.”
