Before this patch, gpio_configure_pads_with_override called
program_gpios once for each GPIO that needed to be configured which
resulted in base_num_pads - 1 unneeded master_switch_set/
master_switch_clr sequences for the gpio_configure_pads_with_override
call. Instead implement gpio_configure_pads_with_override as the more
generic function and program_gpios as a special case of that which
passes an empty override configuration and override pad number to
gpio_configure_pads_with_override.

In addition to that, drawcia needs to be update reset_gpio depending

common location allows platforms with the same SPD requirements to share
SPD files, reducing duplication compared to storing SPDs in soc/ and

For each memory technology there are multiple sets of SPDs. Each set
corresponds to a set of platforms with different SPD requirements, e.g.
due to different memory training code expectations. A manifest file
(platforms_manifest.generated.txt) lists the platform -> set mappings.

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).

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
