Hao Wang 634c7a4450 lib/smbios: Add a config string for BIOS Vendor in SMBIOS Type 0
BIOS Vendor in SMBIOS Type 0 would be who built the firmware so create a
config string with default "coreboot" to make it changeable. Vendors
could update it by adding a Kconfig in the site-local directory.

Xi Chen 35fb55ac3d soc/mediatek: Enable DRAM scramble on fast calibration flow
No matter what DRAM calibration is performed, DRAM scramble should be

scramble is enabled only if full calibration is performed. Correct the

Felix Held 47ed2714c8 soc/amd/common/block/acpi/ivrs: conditionally generate eMMC entry
The eMMC entry in the IVRS table should only be generated if an eMMC
controller is present in the SoC.

Where the PCI_DEVFN(0x13, 1) is from is currently unclear to me. There
is no PCI device 0x13 on bus 0 and the eMMC controller is also an MMIO
device and not a PCI device, but this is what the reference code does.
My guess would be that it mainly needs to be a unique PCI device that
won't collide with any existing PCI device in the SoC. Add a comment
about this too.

Subrata Banik 2172a6336a soc/intel/common/block/cse: Retrieve CSE RW FW version conditionally
This patch introduces a newer config to store the CSE RW FW version into
the CBMEM. Prior to that CSE RW FW version was fetched unconditionally
and ended up increasing the boot time by 7ms to 20ms depending on the
SoC arch (including CSE arch).

The way to retrieve the CSE firmware version is by sending the HECI
command to read the CSE Boot Partition (BP) info. The cost of sending
HECI command to read the CSE FW version is between 7ms-20ms (depending
on the SoC architecture) hence,ensure this feature is platform specific
and only enabled for the platformthat would like to store the CSE version into the CBMEM.

to save 18ms of the boot time.

when this was not requested with the IORESOURCE_ABOVE_4G flag.

Tested on kontron/ktqm77 where the issue could be reproduced with

This patch uses the "generic" variable name as "version" while storing
the MRC cache data instead referring to the FSP-M version or MRC
version. Hence, updated all the instances of `fsp_version/fspm_version`
with `version`.

Also introduces the new option to the MRC cache
version that allows SoC users to store the MRC cache version based on
the supported EDK2 version. Intel FSP built with EDK2 version 202302
onwards has support to retrieve the MRC version by directly parsing
the binary.

Additionally, added the helper function `fsp_mrc_version()` and
corresponding header file to read the MRC version from the FSP binary.

Nico Huber 9260ea60bf allocator_v4: Use memranges only for toplevel
During phase 1 of the resource allocation we gather all the size
requirements. Starting from the leafs of our devicetree, we cal-
culate the requirements per bus, until we reach the resource do-
main.

However, because alignment plays a role, we can't just accumulate
the sizes of all resources on a bus. Instead, we already sort all
the resources per bus to predict their relative placement, inclu-
ding alignment gaps. Then, phase 2 has to perform the final allo-
cations with the exact same relative placement.

This patch introduces a very simple mechanism to avoid repeating
all the calculations: In phase 1, we note the relative `base` of
each resource on a bus. And after we allocated all the resources
directly below the domain in phase 2, we add the absolute `base`
of bridge resources to the relative `base` of child resources.

This saves most of the computational complexity in phase 2. How-
ever, with a shallow devicetree with most devices directly below
the domain, this won't have a measurable impact.

Example after phase 1:

  domain
    |
    `-- bridge #0
          |   res #0, base 0x000000 (relative),
          |   size 12M, align 8M
          |
          |-- device #0
          |         res #1, base 0x800000 (relative),
          |         size 4M, align 4M
          |
          `-- bridge #1
                |   res #2, base 0x000000 (relative),
                |   size 8M, align 8M
                |
                `-- device #1
                          res #3, base 0x000000 (relative),
                          size 8M, align 8M

After phase 2 allocation at the domain level (assuming res #0 got
0xa000000 assigned):

  domain
    |
    `-- bridge #0
          |   res #0, base 0xa000000 (absolute),
          |   size 12M, align 8M
          |
          |-- device #0
          |         res #1, base 0x800000 (relative),
          |         size 4M, align 4M
          |
          `-- bridge #1
                |   res #2, base 0x000000 (relative),
                |   size 8M, align 8M
                |
                `-- device #1
                          res #3, base 0x000000 (relative),
                          size 8M, align 8M

Now, all we need to do is to add the `base` of bridge resources
recursively. Starting with resources on the bus below bridge #0:

  domain
    |
    `-- bridge #0
          |   res #0, base 0xa000000 (absolute),
          |   size 12M, align 8M
          |
          |-- device #0
          |         res #1, base 0xa800000 (absolute),
          |         size 4M, align 4M
          |
          `-- bridge #1
                |   res #2, base 0xa000000 (absolute),
                |   size 8M, align 8M
                |
                `-- device #1
                          res #3, base 0x000000 (relative),
                          size 8M, align 8M

And finally for resources on the bus below bridge #1:

  domain
    |
    `-- bridge #0
          |   res #0, base 0xa000000 (absolute),
          |   size 12M, align 8M
          |
          |-- device #0
          |         res #1, base 0xa800000 (absolute),
          |         size 4M, align 4M
          |
          `-- bridge #1
                |   res #2, base 0xa000000 (absolute),
                |   size 8M, align 8M
                |
                `-- device #1
                          res #3, base 0xa000000 (absolute),

Nico Huber 5226301765 allocator_v4: Treat above 4G resources more natively
We currently have two competing mechanisms to limit the placement of
resources:

 1. the explicit `.limit` field of a resource, and
 2. the IORESOURCE_ABOVE_4G flag.

This makes the resource allocator unnecessarily complex. Ideally, we
would always reduce the `.limit` field if we want to "pin" a specific
resource below 4G. However, as that's not done across the tree yet,
we will use the _absence_ of the IORESOURCE_ABOVE_4G flag as a hint
to implicitly lower the `limit` of a resource. In this patch, this
is done inside the effective_limit() function that hides the flag
from the rest of the allocator.

To automatically place resources above 4G if their limit allows it,
we have to allocate from top down. Hence, we disable the prompt for
RESOURCE_ALLOCATION_TOP_DOWN and turn it on by default. Platforms
that are incompatible should be fixed, but can also override the
default as a temporary measure.

One implication of the changes is that we act differently when a
cold-plugged device reports a prefetchable resource with 32-bit
limit. Before this change, we would fail to allocate the resource.
After this change, it forces everything on the same root port below
the 4G line.

A possible solution to get completely rid of the IORESOURCE_ABOVE_4G
flag would be rules to place resources of certain devices below 4G.
For instance, the primary VGA device and storage and HID devices
could be made available to a payload that can only address 32 bits.

For now, effective_limit() provides us enough abstraction as if the
`limit` would be the only variable to consider. With this, we get
rid of all the special handling of above 4G resources during phase 2
of the allocator. Which saves us about 20% of the code :D

An earlier version of this change (commit 117e436115) had to be
reverted because of missing resource reservations in platform code.
This is worked around now with commit ae81497cb6 (device/pci:
Limit default domain memory window).

Felix Singer 743242b4aa treewide,intel/skylake: Use boolean type for s0ix_enable dt option
Using the boolean type and the true/false macros give the reader a
better understanding about the option. Thus, use the bool type for the
attribute and use the macros for assignments.

Skylake mainboards which use that option were changed by the following
command ran from the root directory.

    socs="SOC_INTEL_(SKYLAKE|KABYLAKE|SKYLAKE_LGA1151_V2)" && \
    option="s0ix_enable" && \
    grep -Er "${socs}" src/mainboard | \
        cut -d ':' -f 1 | \
        awk -F '[/]' '{print $1"/"$2"/"$3"/"$4}' | \
        xargs grep -r "${option}" | \
        cut -d ':' -f 1 | \
        xargs sed -i'' -e "s/${option}\".*\=.*\"1\"/${option}\" \= true/g"
