This patch clarifies the definition of google_chromeec_command.
Currently absence of the definition isn't causing any problem because
wrapper APIs check 'ret != 0' or wrapper APIs check 'ret < 0' for an
interface which returns only negative error codes.
However, there is a chance that a new wrapper API will be addedl which
check 'ret < 0' to catch errors, assuming other interfaces behave the same.
Or existing wrapper APIs will be broken as soon as they're compiled for
another interface.

coreboot performs MP-Init in a parallel way. That leads to the fact
that the order, in which the CPUs are woken up, can vary from boot to
boot. The creation of the MADT table just parses the devicetree and
takes the CPUs reported there as it is for creating the single local
APIC entries. Therefore, the OS will see different order of CPUs.
There are CPUs out there (like Apollo Lake for example) which have
shared caches on core-level and if the order is random this can end up
in assigning cores to different tasks or even OSes (in a virtual
environment) which uses the same cache. This in turn will produce
performance penalties across these distributed tasks/OSes.
Though there is a way to discover the core- and cache-topology it will
in the end be necessary to take the APIC-ID into account. To simplify
it, one can achieve the same output by sorting the APIC-IDs in an
ascending order. This will lead to the fact that CPUs that share a given
cache will be reported right next to each other in the MADT.

extended to cover other datasets like strings if needed.
The reasons for choosing bubble sort are:
* it is a simple algorithm
* bubble sort is stable, i.e. it does not exchange entries which are not
needed to be sorted as they are already in order

Rework the Makefile to default to MrChromebox's coreboot_fb branch, but
also allow for aribitrary commits from upstream Tianocore to be used

Ensure the branch is synced on each build, as long as working directory

Eliminate TIANOCORE_MASTER as a selectable build target, since unpatched
it is unlikely to boot on any device. It can easily be specified via
the 'revision' option if desired.

When <symbols.h> was first introduced, it only declared a handful of
regions and we didn't expect that too many architectures and platforms
would need to add their own later. However, our amount of platforms has
greatly expanded since, and with them the need for more special memory
regions. The amount of code duplication is starting to get unsightly,
and platforms keep defining their own <soc/symbols.h> files that need
this as well.
This patch adds another macro to cut down the definition boilerplate.
Unfortunately, macros cannot define other macros when they're called, so
referring to region sizes as _name_size doesn't work anymore. This patch
replaces the scheme with REGION_SIZE(name).
Not touching the regions in the x86-specific <arch/symbols.h> yet since
they don't follow the standard _region/_eregion naming scheme. They can

For CFL and WHL, Microcode is being loaded from FIT. Both
supports the PRMRR/SGX feature. If This is supported the FIT
microcode load will set the msr (0x08b) with the Patch id one
less than the id in the microcode binary. This results in
Microcode getting reloaded again in bootblock and ramstage.
Avoid the microcode reload by checking for PRMRR support.
CFL and WHL CPU die are based on KBL CPU so we need to have
this check, where CNL CPU die is not based on KBL CPU so
skip this check for CNL.
