This change adds mem_list_variant.txt that contains the list of

gen_part_id.go using mem_list_variant.txt.
In the final change of the series, all dedede variants will be

Differences in auto-generated SPD from current SPD are as follows:
Part: MT53E512M32D2NP-046 WT:E
Byte# Current New Explanation
4 0x15 0x16 This part has only 1 die. Hence,
density per die is 16Gb.
6 0x90 0x04 1 die in package and 2 channels per
die.
9 0x40 0x00 Unused by MRC.
19 0x0F 0xFF As per JEDEC spec, tckMax should be
100ns. So, value should be 0xFF as
per datasheet.
123 0x00 0xE5 Fine offset for taa. Expected value
is 0xE5 as per datasheet.
125 0xE1 0xE0 Fine offset for tckMin. As per

Splitting static HAVE_SMI_HANDLER variable helps to manage cases

There have been changes to the way device properties are supported
in Linux[1] and Windows[2] which add flexibilty:
- non-standard UUIDs can be used instead of only ACPI_DP_UUID
- support for multiple different packages within the _DSD that
associate different properties with unique UUIDs.
To handle this I extracted the part that does the write of UUID and
properties to a separate function and defined a new PACKAGE type
which has the custom UUID as a name and can be used the same way that
child properties are today.
For example a PCIe root port for a USB4 port has a standard property
indicating the USB4 reference, and then two custom properties which
are defined for different attributes.
Example code:
/* Create property table */
acpi_dp *dsd = acpi_dp_new_table("_DSD");
acpi_dp_add_reference(dsd, "usb4-port", usb4_path);
/* Add package for hotplug */
acpi_dp *pkg = acpi_dp_new_table("6211e2c0-58a3-4af3-90e1-927a4e0c55a4");
acpi_dp_add_integer(pkg, "HotPlugSupportInD3", 1);
acpi_dp_add_package(dsd, pkg);
/* Add package for external port info */
pkg = acpi_dp_new_table("efcc06cc-73ac-4bc3-bff0-76143807c389");
acpi_dp_add_integer(pkg, "ExternalFacingPort", 1);
acpi_dp_add_package(dsd, pkg);
/* Write all properties */
acpi_dp_write(dsd);
Resulting ACPI:
Scope (\_SB.PCI0.TRP0)
{
Name (_DSD, Package ()
{
ToUUID ("daffd814-6eba-4d8c-8a91-bc9bbf4aa301")
Package ()
{
Package () { "usb4-port", \_SB.PCI0.TDM0.RHUB.PRTA }
},

Add PCIe enumeration and resource assignment/allocation.
Xeon-SP processor family has split IIO design, where PCIe domain 0 is
split into multiple stacks. Each stack has its own resource ranges (eg.
IO resource, mem32 resource, mem64 resource). The stack itself is not
PCIe device, it does not have config space to be probed/programmed.
The stack is programmed by FSP. coreboot needs to take into account of
stack when doing PCIe enumeration and resource allocation.
Current coreboot PCIe resource allocator does not support the concept of
split IIO stack, thus entire support is done locally in this patch.
In near future, improvements will be done, first generalize for xeon-sp,
then generalize for coreboot PCIe device code.

offsets for ACPI_PM are incorrectly configured for picasso SoC.
Especially incorrect ACPI_PM_TMR_BLK makes kernel to spend 10 sec for
trying to testing it on wrong address.
Fix them to correct offset with hack for GPE0_BLK.

Lower 20bits of TOLUD and TOLM registers include 19 reserved bits and
1 lock bit. If lock bit is set, then systemagent.asl would end up
reporting the base address of low MMIO incorrectly i.e. off by 1.
This change masks the lower 20 bits of TOLUD and TOM registers when
exposing it in the ACPI tables to ensure that the base address of low
MMIO region is reported correctly.
