On some x86 platforms (skylake, apollolake), we observe reboots at
different steps during the FSP initialization. These additional reboots
result in loss of recovery request because vboot_reference library
clears recovery request on vbnv once verification is complete and it has
made a decision about which boot path to take(normal/dev, slot-a/slot-b,
recovery).
Provide a way to allow mainboards/chipsets to inform recovery module in
vboot2 to save recovery reason to survive unexpected reboots. The
recovery reason is set in vbnv after vboot_reference library completes
its verification and clears the reason in vbnv while jumping to
payload.

The fixed MTRRs cover the range [0:1MiB). While calculating the

When no CFLAGS are explicitly provided to it, the GMP configure script
will figure out the best optimization flags to use on its own. In
particular, it will setup the march, mfpu and mtune flags based on
hardware detection.
However, when CFLAGS are provided, they are used as-is and such
detection doesn't happen. When the march, mfpu and mtune flags are not
provided (which happens when GMP wasn't built already), not only will
related optimizations be disabled, but some code might not build because
of missing support. This happens with NEON instructions on ARMv7 hosts.
Thus, it is better not to set CFLAGS and leave it up to the GMP
configure script to get them right and still reuse those later.

FSP 2.0 spec only defines 2 reset request (COLD, WARM) exit codes. The
rest 6 codes are platform-specific and may vary. Modify helper function
so that only basic resets are handled and let SoC deal with the rest.

At first boot CSE spends long time preparing media for use. As result
it may not be able to deal with a CPU reset. Add reset_prepare()
callback that polls CSE readiness.

TEST=build with release version of fsp, reboot, observe polling for
CSE, then proper reboot happening
