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.

Add an implementation for Bubble sort. For now, only integers can be
sorted in an ascending or descending order. It can be later simply
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

Rather than attempt to maintain patches against upstream Tianocore, use
MrChromebox's coreboot framebuffer branch as the default build target.
Rework the Makefile to default to MrChromebox's coreboot_fb branch, but
also allow for aribitrary commits from upstream Tianocore to be used
as build targets.
Ensure the branch is synced on each build, as long as working directory
is clean, and that switching between commits or trees is handled sanely.
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.
Test: build for the default stable target, for upstream/master
as the specified revision, and for an arbitrary valid commit hash.

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
be converted later if desired.

removing const modifier as we'll need to set these fields
incrementally now. For the single channel configuration, we set
MemorySpdPtr10 to 0. For the dual channel configuration, we set
MemorySpdPtr10 to MemorySpdPtr00.
BUG=b:123062346, b:122959294
BRANCH=None
TEST=Boot into current boards and ensure that we have 2 channels as expected

This patch feeds PsysPmax setting to FSP through UPD and adds a
psys_pmax member in chip information so that we can set PsysPmax
through DT. The PsysPmax needs to be set correctly mapping to maximum
system power. Otherwise, system performance would be limited due to
the default PsysPmax setting in FSP is only 21W.
BUG=None
BRANCH=None
TEST=Set psys_pmax to an example value eg 101 in DT && put debug code
in FSP to print the PsysPmax value before sending to Pcode, ensure
the setting is correctly programmed.

This patch adds the _DSM method 5 and 6 for entering and exiting S0ix.
The _DSM method gets injected into DSDT table and called from kernel.
LPIT table is hardcoded in this patch but the proper way to implement
is to use inject_dsdt to make the _DSM methods available for soc's to
implement.
Calling the LPIT table from mainboard here so that with the current
implementation the platforms which do not have lpit support throw
compilation error.

The requirements read a bit as if we only encourage coreboot experts to
try to take on these projects. These requirements should be understood
as "this is what you'll need to learn", hopefully guiding interested
people in picking a project that suits their interests.
