Serial Presence Detect (SPD) data for memory modules is used by Memory
Reference Code (MRC) for training the memory. This SPD data is
typically obtained from part vendors but has to be massaged to format
it correctly as per JEDEC and MRC expectations. There have been
numerous times in the past where the SPD data used is not always
correct.
In order to reduce the manual effort of creating SPDs and generating
DRAM IDs, this change adds tools for generating SPD files for LPDDR4x
memory used in memory down configurations on Intel Tiger Lake (TGL)
and Jasper Lake (JSL) based platforms. These tools generate SPDs
following JESD209-4C specification and Intel recommendations (doc
Two tools are provided:
* gen_spd.go: Generates de-duplicated SPD files using a global memory
part list provided by the mainboard in JSON format. Additionally,
generates a SPD manifest file (in CSV format) with information about
what memory part from the global list uses which of the generated
SPD files.
* gen_part_id.go: Allocates DRAM strap IDs for different LPDDR4x
memory parts used by the board. Takes as input list of memory parts
used by the board (with one memory part on each line) and the SPD
manifest file generated by gen_spd.go. Generates Makefile.inc for
integrating the generated SPD files in the coreboot build.

This adds a hook so that a payload can optionally perform USB service
functions in conjunction with regular USB port status polling. In
particular, this allows depthcharge to control the state of an
external USB mux. Some SoCs like Tiger Lake have a USB mux for Type-C
ports that must be kept in sync with the state of the port as reported
by the TCPC. This can be achieved by hooking into the poll routine to
refresh the state of the USB mux.

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 }
},
ToUUID ("6211e2c0-58a3-4af3-90e1-927a4e0c55a4"),

{

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.

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.
