This mitigates the Memory Sinkhole issue (described on
https://github.com/xoreaxeaxeax/sinkhole) by checking for the issue and
crashing the system explicitly if LAPIC overlaps ASEG.
This needs to happen without a data access (only code fetches) because
data accesses could be tampered with.
Don't try to recover because, if somebody tried to do shenanigans like
these, we have to expect more.
Sandybridge is safe because it does the same test in hardware, and
crashes. Newer chipsets presumably do the same.
This needs to be extended to deal with overlapping TSEG as well.

To support x86 verstage one needs a working buffer for
vboot. That buffer resides in the cache-as-ram region
which persists across verstage and romstage. The current
assumption is that verstage brings cache-as-ram up
and romstage tears cache-as-ram down. The timestamp,
cbmem console, and the vboot work buffer are persistent
through in both romstage and verstage. The vboot
work buffer as well as the cbmem console are permanently
destroyed once cache-as-ram is torn down. The timestamp
region is migrated. When verstage is enabled the assumption
is that _start is the romstage entry point. It's currently
expected that the chipset provides the entry point to
romstage when verstage is employed. Also, the car_var_*()
APIs use direct access when in verstage since its expected
verstage does not tear down cache-as-ram. Lastly, supporting
files were added to verstage-y such that an x86 verstage
will build and link.

The x86 bootblock linking is a mess. The bootblock is treated in
a very special manner, and never received the update to link-time
garbage collection.
On newer x86 platforms, the boot media is no longer memory-mapped.
That means we need to do a lot more setup in the bootblock. ROMCC is
unsuitable for this task, and walkcbfs only works on memory-mapped
CBFS. We need to revise the x86 bootflow for this new case.
The approach this patch series takes is to perform CAR setup in the
bootblock, and load the following stage (either romstage or verstage)
from the boot media. This approach is not new, but has been done on
our ARM ports for years.
Since we will be adding .c files to the bootblock, it is prudent to
use link-time garbage collection. This is also consistent to how we
do things on other architectures. Unification FTW!

This is a sad story. We have three different code paths for
sandybridge and ivybridge: proper native path, google MRC path, and,
everyone's favorite: Intel FSP path. For the purpose of this patch,
the FSP path lives in its own little world, and doesn't concern us.
Since MRC was first, when native files and variables were added, they
were suffixed with "_native" to separate them from the existing code.
This can cause confusion, as the suffix might make the native files
seem parasitical.
This has been bothering me for many months. MRC should be the
parasitical path, especially since we fully support native init, and
it works more reliably, on a wider range of hardware. There have been
a few board ports that never made it to coreboot.org because MRC would
hang.
gigabyte/ga-b75m-d3h is a prime example: it did not work with MRC, so
the effort was abandoned at first. Once the native path became
available, the effort was restarted and the board is now supported.
In honor of the hackers and pioneers who made the native code
possible, rename things so that their effort is the first class
citizen.
