Use acpi_align_current to align the ACPI tables on a 16 byte boundary.
This changes the alignment of the HEST, IVRS, SRAT and SLIT tables from
8 bytes to 16 bytes. The alignment of the ALIB and PSTATE SSDT tables
was already 16 bytes before, so the alignment of those isn't changed.

This new option is hooked with `SkipMbpHob` UPD and is always

Currently most of the FSP debug messages (when enabled) are truncated
due to insufficient size of cbmem buffer.
Increase premem cbmem console size to 0x16000 bytes and cbmem buffer
size to 0x100000 bytes so that cbmem buffer can contain most of the
debug logs when FSP debug messages are enabled.

Current size of the cbmem buffer (128KB) is insufficient to contain the
complete debug logs which is more than 166KB hence, cbmem console buffer has wound off to contain the maximum possible debug messages within the allocated buffer as results, we are seeing truncated debug message while looking into the cbmem console.
This patch increases cbmem buffer size to 256KB so that the complete
debug log can be stored in it.

Intel Ice Lake is unmaintained and the only user of this platform ever
was the Intel CRB (Customer Reference Board). As it looks like, it was
never ready for production as only engineering sample CPUIDs are
supported.
As announced in the 4.19 release notes, remove support for Intel
Icelake code and move any maintenance on the 4.19 branch.
This affects the following components and their related code:
* Intel Ice Lake SoC
* Intel Ice Lake CRB mainboard
* Documentation

The parameter 'maxlen' can be a bit confusing as it actually is
referring to the size of the destination memory block where the
requested parameter is stored to. Rename it to 'dstsize' and change
the type to size_t to be more clear here.
In addition, add a comment line for this parameter in the description
of the function 'hwilib_get_field()'.

The patch fixes indication of incorrect `prev_sleep_state` on the next
boot after global reset trigger. The existing code misses an important check about `if PCH doesn't set the WAK_STS` while checking power
failure. As a result, every early warm/global reset is considered
as power failure after looking into the PMC MMIO CON-A register
alone (as ignoring the ACPI PM_CTRL.WAK_STS bit).
As per the code comment this code logic is expected to check the power
failure reason if PCH doesn't set the WAK_STS while waking from G3

This patch refactors the mainboard_romstage_entry() function to avoid
redundant chipset programming caused by global reset due to CSE FW
sync operation. Hence, keeping only the minimal and mandatory
operations required to perform CSE FW sync successfully.
This would help to optimize the boot flow by removing redundant
programming like SA, SMBUS twice in every CSE FW update path.
TEST=Able to build and boot Google/Rex successfully.

The AMD SoCs no longer have a variable position for EFS - it's now fixed
at 0xff020000 - 128KiB into the 16MiB ROM decode region.
It's a little more complex than that because the chip can be larger than
16MiB, and the entire ROM can be decoded if mapped above the 4GiB
boundary, but we don't currently support doing that in coreboot, so this
is enough for now.
