Normally for vboot-enabled x86 board, the VBNV region is stored in CMOS
and backed up to flash (RW_NVRAM). However, on the very first boot after
a flash of the full SPI image (so RW_NVRAM is empty), if
RTC_BATTERY_DEAD is set, coreboot persistently requests recovery before
FSP-M finishes (which appears to be the current location that
RTC_BATTERY_DEAD is cleared on this platform). This is because
vbnv_cmos_failed() will still return 1. Therefore, immediately after
reading RTC_BATTERY_DEAD, it is cleared. This prevents an infinite boot
loop when trying to set the recovery mode bit.
Note that this was the behavior for previous generations of Intel PMC
programming as well (see southbridge/intel, soc/skylake, soc/broadwell,
etc).

The `CaVrefConfig` FSP-M UPD describes how the on-die Vref generators
are connected to the DRAM. With the exception of an early Skylake RVP
board (which doesn't have coreboot support), mainboards using DDR3 or
LPDDR3 memory should set `CaVrefConfig` to 0, whereas mainboards with
DDR4 should set `CaVrefConfig` to 2. MRC uses this information during
memory training, so it is important to use the correct value to avoid
any issues, such as increased power usage, system instability or even
boot failures.
However, several Skylake DDR4 mainboards don't set `CaVrefConfig` to 2.
Although they can boot successfully, it's not optimal. For boards that
set `DIMM_SPD_SIZE` to 512 (DDR4 SPD size), set `CaVrefConfig` to 2.

vboot_reference is introducing a new field (ctx) to store the current
boot mode in crrev/c/2944250 (ctx->bootmode), which will be leveraged
in both vboot flow and elog_add_boot_reason in coreboot.
In current steps of deciding bootmode, a function vb2ex_ec_trusted
is required. This function checks gpio EC_IN_RW pin and will return
'trusted' only if EC is not in RW. Therefore, we need to implement
similar utilities in coreboot.
We will deprecate vb2ex_ec_trusted and use the flag,
VB2_CONTEXT_EC_TRUSTED, in vboot, vb2api_fw_phase1 and set that flag
in coreboot, verstage_main.
Also add a help function get_ec_is_trusted which needed to be
implemented per mainboard.

The PCIe WWAN module used on brya0 requires control over 4 signals to
successfully power it on. It is desirable to do this before passing
control to the payload, because the modem requires a ~10 seconds
initialization phase before it can be used.
The corrected sequence looks like:
1) Drive device into full reset and enable power in bootblock
2) Deassert FCPO in romstage, after power rails stabilize
3) Deassert WLAN_RST#, then WLAN_PERST# in ramstage
