Since linux commit f9ba70535dc12d9eb57d466a2ecd749e16eca866
"[PATCH] Increase number of e820 entries hard limit from 32 to 128"
made in 2005 the number of e820 entries passed from the bootloader
is 128. Use the boot protocol version to check for support of
128 entries and use them if necessary.
Tested on IBM/SBP1:
Fixes booting a Linux payload when more than 32 entries are present
in the memory table, which can easily happen on a 4 socket platform.

This patch eliminates coreboot from loading microcode from RW CBFS
(when the RO descriptor is locked, which indicates a fixed RO image)
because the kernel can already patch the microcode on BSPs and APs
while booting to OS.
This may be a chance to lower the burden on the AP FW side because
patching microcode on in-field devices is subject to firmware updates,
which are rarely published and, if required, must go through the
firmware qualification testing procedure (which is costly, unlike
kernel updates for ucode updates).
1. The FIT loads the necessary microcode from the RO during reset.
2. Reloading microcode from RW CBFS impacts boot time
(~60ms, core-dependent).
3. The kernel can still load microcode updates.
ChromeOS devices leverage RO+RW-A/RW-B booting. The RO's microcode is
sufficient for initial boot, and the kernel can apply updates later.
BUG=none
TEST=Verified boot optimization; in-field devices skip RW-CBFS microcode
loading when RO is locked.

When 'reset_gpio' and 'enable_gpio' properties are defined in
overridetree.cb, the kernel will power on the FPMCU. If the device was
previously enabled the kernel will reset it.
To avoid situation in which the FPMCU is powered on and reset later we
leave the FPMCU powered off in coreboot and started by the kernel. This
is exactly what other boards do (e.g. brya).
TEST=Boot the board (e.g. karis) and make sure the FPMCU was booted once
(e.g. examine FPMCU console logs)

Setting the EC interrupt GPIO as an APIC is able to solve many
problems that we are currently seeing:
1. Routing through the APIC make the IRQ# associated with this pin
unavailable to claim for other devices in the kernel. This is causing
EC interrupts to not work.
2. Since EC interrupt are not working, we are not able to flash the
EC from the DUT.
3. Also, the GPI_INT configuration does not allow us to set the
polarity of the GPIO, which means that it is by default set as active
high. As a result, we are seeing an excessive number of host command
interrupts to the EC. This disappears when we change the
configuration to APIC and set the polarity as INVERT.
BUG=b:319129926,b:324707182
BRANCH=None
TEST=1. After boot up, check if ec_cros_lpcs driver was successfully
registered. Look for the following string:
"cros_ec_lpcs GOOG0004:00: Chrome EC device registered"
2. Make sure can flash the EC image from the DUT
3. Make sure EC console is not getting continuous stream of host
commands.

Commit 977b8e83cb ("mb/emulation/qemu-aarch64: Add MMU support") adds
MMU support for ARM64 QEMU VMs, but registers a limited 1GiB region for
the DRAM, with a note that ramstage should update it.
However on recent versions of QEMU "virt" VMs, accessing RAM outside
this registered region results in an exception even if the address is
backed by actual RAM. This interferes with RAM detection which catches
these exceptions, effectively limiting us to detecting a maximum 1GiB of
RAM even if more is available.
Register the entire RAM space to MMU instead of just the 1GiB, so that
probing RAM addresses can correctly detect how much RAM we have.
