5e007808cd smbios: Fix type 17 for Windows 10
The `GetPhysicallyInstalledSystemMemory` API call, at least on Windows
10, returns an error if SMBIOS tables are invalid. Various tools use
this API call and don't operate correctly if this fails. For example,
the "Intel Processor Diagnostic Tool" program is affected.

Windows then guesses the physical memory size by accumulating entries
from the firmware-provided memory map, which results in a total memory
size that is slightly lower than the actual installed memory capacity.

To fix this issue, add the handle to a type 16 entry to all type 17
entries.

Add new fields to struct memory_info and fill them in Intel common code.
Use the introduced variables to fill type 16 in smbios.c and provide
a handle to type 17 entries.

Besides keeping the current behaviour on intel/soc/common platforms, the
type 16 table is also emitted on platforms that don't explicitly fill
it, by using the existing fields of struct memory_info.

Tested on Windows 10:
The GetPhysicallyInstalledSystemMemory API call doesn't return an error
anymore and the installed memory is now being reported as 8192 MiB.

a4c0e1a51f ACPI S3: Clean up resume path
Remove the obscure path in source code, where ACPI S3 resume
was prohibited and acpi_resume() would return and continue
to BS_WRITE_TABLES.

The condition when ACPI S3 would be prohibited needs to be
checked early in romstage already. For the time being, there
has been little interest to have CMOS option to disable
ACPI S3 resume feature.

79572e4f32 src: Make HAVE_CF9_RESET set the FADT reset register
All supported x86 chips select HAVE_CF9_RESET, and also use 0xcf9 as
reset register in FADT. How unsurprising. We might as well use that
information to automatically fill in the FADT accordingly. So, do it.

To avoid having x86-specific code under arch-agnostic `acpi/`, create a
new optional `arch_fill_fadt` function, and override it for x86 systems.

Tested on Asus P8Z77-V LX2 with Linux 5.7.6 and Windows 10 at the end of
the patch train, both operating systems are able to boot successfully.

b8fba86b14 Kconfig: Escape variable to accommodate new Kconfig versions
Kconfig 4.17 started using the $(..) syntax for environment variable
expansion while we want to keep expansion to the build system.
Older Kconfig versions (like ours) simply drop the escapes, not
changing the behavior.

While we could let Kconfig expand some of the variables, that only
splits the handling in two places, making debugging harder and
potentially messing with reproducible builds (e.g. when paths end up
in configs), so escape them all.

Also, linker scripts have LOG2CEIL which comes in handy to enforce
MTRR alignments.

46514c2b87 treewide: Add Kconfig variable MEMLAYOUT_LD_FILE
This change defines a Kconfig variable MEMLAYOUT_LD_FILE which allows
SoC/mainboard to provide a linker file for the platform. x86 already
provides a default memlayout.ld under src/arch/x86. With this new
Kconfig variable, it is possible for the SoC/mainboard code for x86 to
provide a custom linker file as well.

Makefile.inc is updated for all architectures to use this new Kconfig
variable instead of assuming memlayout.ld files under a certain
path. All non-x86 boards used memlayout.ld under mainboard
directory. However, a lot of these boards were simply including the
memlayout from SoC. So, this change also updates these mainboards and
SoCs to define the Kconfig as required.

BUG=b:155322763
TEST=Verified that abuild with --timeless option results in the same
coreboot.rom image for all boards.

58b8054cca arch/x86: Fix id section in linker script
Builds where RESET_X86_VECTOR is adjusted would create unintentionally
large bootblock files since id section can move far away from .reset
and .text. Some builds segfault or may try to create close to 4 GB
large intermediate build objects.

For cases where build is successful, id section would not reside within
REGION(program) or REGION(bootblock).

A proper fix to always place the ID data at the end of the coreboot.rom
file is left as follow-up work. For now, just place id section below
.reset.

6cc1e9e81e acpi: Move ACPI table support out of arch/x86 (1/5)
This change moves all ACPI table support in coreboot currently living
under arch/x86 into common code to make it architecture
independent. ACPI table generation is not really tied to any
architecture and hence it makes sense to move this to its own directory.

In order to make it easier to review, this change is being split into
multiple CLs. This is change 1/5 which moves .c files from arch/x86 to
acpi/.

The only acpi files that are still retained under arch/x86 are:
a. acpi_s3.c: This doesn't really deal with ACPI tables. Also, there
are some assumptions in there about SMM which will have to be resolved
if this file needs to be moved to common code.

b. acpi_bert_storage.c/bert_storage.h: This file is currently written
specifically with x86 in mind. So, not moving the file for now.

Motivation for this change: Not all stages on Picasso SoC are targeted
for the same architecture. For example, verstage (if runs before
bootblock) will be targeted for non-x86. This makes it difficult to
add device tree to verstage which would be required to get to SoC
configs from the tree. This is because the device tree on x86
platforms currently contains a lot of devices that require ACPI
related enums and structs (like acpi_gpio, acpi_pld, acpi_dp and so
on). Hence, this change removes all ACPI table support out of
arch/x86.

c1adeb68a0 arch/x86/acpi_device: Allow empty child references
Currently if a child table is created and added to a property list
without adding any properties to that child it will generate an
empty package.  For example:

struct acpi_dp *dsd = acpi_dp_new_table("_DSD");
struct acpi_dp *prop = acpi_dp_new_table("PROP");
acpi_dp_add_child(dsd, "dsd-prop", prop);
acpi_dp_write(dsd);

Results in an empty PROP package:

Name (_DSD, Package (2)
{
  ToUUID("dbb8e3e6-5886-4ba6-8795-1319f52a966b")
  Package (1) {
    Package (2) {
      "dsd-prop",
      "PROP"
    }
  }
}
Name (PROP, Package (0)
{
}

Empty packages don't seem to be explicitly forbidden, but they don't
serve a purpose with device properties.  Instead, if packages without
any properties or children are skipped then this empty package is not
written and the added child property can refer to another property that
is already defined.

This allows creating property references to existing tables, which can
save duplication and namespace collision issues with nested properties.

ca928c6768 arch/x86: Implement RESET_VECTOR_IN_RAM
Add support for devices with the reset vector pointing into DRAM.  This
is a specific implementation that assumes a paradigm of AMD Family 17h
(a.k.a. "Zen").  Until the first ljmpl for protected mode, the core's
state appears to software like other designs, and then the actual
physical addressing becomes recognizable.

These systems cannot implement cache-as-RAM as in more traditional
x86 products.  Therefore instead of reusing CAR names and variables,
a substitute called "earlyram" is introduced.  This change makes
adjustments to CAR-aware files accordingly.

Enable NO_XIP_EARLY_STAGES.  The first stage is already in DRAM, and
running subsequent stages as XIP in the boot device would reduce
performance.

Finally, add a new early_ram.ld linker file.  Because all stages run in
DRAM, they can be linked with their .data and .bss as normal, i.e. they
don't need to rely on storage available only at a fixed location like
CAR systems.  The primary purpose of the early_ram.ld is to provide
consistent locations for PRERAM_CBMEM_CONSOLE, TIMESTAMP regions, etc.
across stages until cbmem is brought online.

21a4053fde rules.h: Rename ENV_VERSTAGE to ENV_SEPARATE_VERSTAGE
When CONFIG_SEPARATE_VERSTAGE=n, all verstage code gets linked into the
appropriate calling stage (bootblock or romstage). This means that
ENV_VERSTAGE is actually 0, and instead ENV_BOOTBLOCK or ENV_ROMSTAGE
are 1. This keeps tripping up people who are just trying to write a
simple "are we in verstage (i.e. wherever the vboot init logic runs)"
check, e.g. for TPM init functions which may run in "verstage" or
ramstage depending on whether vboot is enabled. Those checks will not
work as intended for CONFIG_SEPARATE_VERSTAGE=n.

This patch renames ENV_VERSTAGE to ENV_SEPARATE_VERSTAGE to try to
clarify that this macro can really only be used to check whether code is
running in a *separate* verstage, and clue people in that they may need
to cover the linked-in verstage case as well.

When using QEMU with TPM enabled there is ~200 KiB of ACPI tables
returned by the fw_cfg interface, so in order to allow this to be

This is seen when using a TPM with qemu as it will hang when

c79e96b4eb security/vboot: Decouple measured boot from verified boot
Currently, those who want to use measured boot implemented within
vboot should enable verified boot first, along with sections such
as GBB and RW slots defined with manually written fmd files, even
if they do not actually want to verify anything.

As discussed in CB:34977, measured boot should be decoupled from
verified boot and make them two fully independent options. Crypto
routines necessary for measurement could be reused, and TPM and CRTM
init should be done somewhere other than vboot_logic_executed() if
verified boot is not enabled.

In this revision, only TCPA log is initialized during bootblock.
Before TPM gets set up, digests are not measured into tpm immediately,
but cached in TCPA log, and measured into determined PCRs right after
TPM is up.

This change allows those who do not want to use the verified boot
scheme implemented by vboot as well as its requirement of a more
complex partition scheme designed for chromeos to make use of the
measured boot functionality implemented within vboot library to
measure the boot process.

TODO: Measure MRC Cache somewhere, as MRC Cache has never resided in
CBFS any more, so it cannot be covered by tspi_measure_cbfs_hook().

8bee86ef23 Revert "acpi: Bump FADT to revision 6"
This reverts commit c8b0f31ca1.

Bumping the FADT table version from 3 to 6 causes
Windows 10 to BSOD with an ACPI BIOS error or simply
fail to boot on multiple platforms (Haswell, Broadwell,
Braswell, Skylake). Revert until the issue can be properly
identified and corrected.

really safe to call cmos_post_code from SMM context. Thus we'll hide the

c83bab62b3 acpi: Be more ACPI compliant when generating _UID
* Add function to generate unique _UID using CRC32
* Add function to write the _UID based on a device's ACPI path

ACPI devices that have the same _HID must use different _UID.
Linux doesn't care about _UID if it's not used.
Windows 10 verifies the ACPI code on boot and BSODs if two devices
with the same _HID share the same _UID.

Fixes BSOD seen on Windows 10.

540a98001d printf: Automatically prefix %p with 0x
According to the POSIX standard, %p is supposed to print a pointer "as
if by %#x", meaning the "0x" prefix should automatically be prepended.
All other implementations out there (glibc, Linux, even libpayload) do
this, so we should make coreboot match. This patch changes vtxprintf()
accordingly and removes any explicit instances of "0x%p" from existing
format strings.

How to handle zero padding is less clear: the official POSIX definition
above technically says there should be no automatic zero padding, but in
practice most other implementations seem to do it and I assume most
programmers would prefer it. The way chosen here is to always zero-pad
to 32 bits, even on a 64-bit system. The rationale for this is that even
on 64-bit systems, coreboot always avoids using any memory above 4GB for
itself, so in practice all pointers should fit in that range and padding
everything to 64 bits would just hurt readability. Padding it this way
also helps pointers that do exceed 4GB (e.g. prints from MMU config on
some arm64 systems) stand out better from the others.

515ef38db4 arch/x86: SMBIOS: Improve core count reporting
Current code uses CPUID leaf 0x1, EBX bits 16:23 to determine number for
"core count". However, it turns out this number has little to do with
real number of cores. According to SDM vol 2A, it stays for "maximum
number of addressable IDs for logical processors in this physical
package". This does not seem to take into account fusing of giving
processor.

The new code determines 'core count' by dividing thread-level cpus by
reported logical cores. This seems to be the only way to arrive
to number of cores as it is reported in official CPU datasheet.

Due to the way CAR teardown is handled in FSP 1.0, the results of

running with FMAP cache. It might be possible to fix this but would make

platforms and hope they die out soon.

Also allow this option to be used by platforms that don't have space for
the cache and want to save a little more code.

cefe89ee79 lib/fmap: Add optional pre-RAM cache
This patch adds an optional pre-RAM cache for the FMAP which most
platforms should be able to use, complementing the recently added
post-RAM FMAP cache in CBMEM. vboot systems currently read the FMAP
about half a dozen times from flash in verstage, which will all be
coalesced into a single read with this patch. It will also help
future vboot improvements since when FMAP reads become "free" vboot
doesn't need to keep track of so much information separately.

In order to make sure we have a single, well-defined point where the new
cache is first initialized, eliminate the build-time hardcoding of the
CBFS section offsets, so that all CBFS accesses explicitly read the
FMAP.

Add FMAP_CACHEs to all platforms that can afford it (other than the
RISC-V things where I have no idea how they work), trying to take the
space from things that look like they were oversized anyway (pre-RAM
consoles and CBFS caches).

To prevent this vboot_prepare() is removed from the vboot_locator

To clarify the change the vboot_prepare() has been renamed to
vboot_run_logic() and calls to initialize vboot have been added at the
following places:

postcar_loader: when VBOOT starts in ROMSTAGE
romstage_loader: when VBOOT starts in BOOTBLOCK

and placed at a predefined offset.

Add assembly code to load the page tables, based on a Kconfig symbol and

7c9a0e8a9c arch/x86: Use the stage argument to implement cbmem_top
Currently all stages that need cbmem need an implementation of a
cbmem_top function.  On FSP and AGESA platforms this proves to be
painful and a pointer to the top of lower memory if often passed via
lower memory (e.g. EBDA) or via a PCI scratchpad register.

The problem with writing to lower memory is that also need to be
written on S3 as one cannot assume it to be still there. Writing
things on S3 is always a fragile thing to do.

A very generic solution is to pass cbmem_top via the program argument.
It should be possible to implement this solution on every
architecture.

Instead trying to figure out which files can be removed from stages
and which cbmem_top implementations need with preprocessor, rename all
cbmem_top implementation to cbmem_top_romstage.

TESTED on qemu-x86.

0d6ddf8da7 cpu/x86/tsc: Flip and rename TSC_CONSTANT_RATE to UNKNOWN_TSC_RATE
The x86 timers are a bit of a mess. Cases where different stages use
different counters and timestamps use different counters from udelays.

The original intention was to only flip TSC_CONSTANT_RATE Kconfig
to NOT_CONSTANT_TSC_RATE. The name would be incorrect though, those
counters do run with a constant rate but we just lack tsc_freq_mhz()
implementation for three platforms.

Note that for boards with UNKNOWN_TSC_RATE=y, each stage will have a
slow run of calibrate_tsc_with_pit(). This is easy enough to fix with
followup implementation of tsc_freq_mhz() for the platforms.

Implementations with LAPIC_MONOTONIC_TIMER typically will not have
tsc_freq_mhz() implemented and default to UNKNOWN_TSC_RATE. However,
as they don't use TSC for udelay() the slow calibrate_tsc_with_pit()
is avoided.

Because x86/tsc_delay.tsc was using two different guards and nb/via/vx900
claimed UDELAY_TSC, but pulled UDELAY_IO implementation, we also switch
that romstage to use UDELAY_TSC.

809b7513a2 soc/intel/common/timer: Make TSC frequency calculation dynamically
tsc_freq_mhz() had a static table of Intel CPU families and crystal
clock, but it is possible to calculate the crystal clock speed dynamically,
and this is preferred over hardcoded table.

On SKL/KBL/CML CPUID.15h.ecx = nominal core crystal clock = 0 Hz
hence we had to use static table to calculate crystal clock.

Recommendation is to make use of CPUID.16h where crystal clock frequency
was not reported by CPUID.15h to calculate the crystal clock.

BUG=b:139798422, b:129839774
TEST=Able to build and boot KBL/CML/ICL.

9172b6920c src: Remove variable length arrays
Variable length arrays were a feature added in C99 that allows the
length of an array to be determined at runtime. Eg.

	int sum(size_t n) {
		int arr[n];
		...
	}

This adds a small amount of runtime overhead, but is also very
dangerous, since it allows use of an unlimited amount of stack memory,
potentially leading to stack overflow. This is only worsened in
coreboot, which often has very little stack space to begin with. Citing
concerns like this, all instances of VLA's were recently removed from the
Linux kernel. In the immortal words of Linus Torvalds [0],

    AND USING VLA'S IS ACTIVELY STUPID! It generates much more code, and
    much _slower_ code (and more fragile code), than just using a fixed
    key size would have done. [...] Anyway, some of these are definitely
    easy to just fix, and using VLA's is actively bad not just for
    security worries, but simply because VLA's are a really horribly bad
    idea in general in the kernel.

This patch follows suit and zaps all VLA's in coreboot. Some of the
existing VLA's are accidental ones, and all but one can be replaced with
small fixed-size buffers. The single tricky exception is in the SPI
controller interface, which will require a rewrite of old drivers
to remove [1].

0c4ed4bd7e arch, include, soc: Use common stdint.h
There are only minimal differences between the architecture specific
stdint.h implementations, so let's tidy them up and merge them together
into a single file. In particular,

- Use 'unsigned long' for uintptr_t. This was already the case for x86
  and riscv, while arm and mips used 'unsigned int', and arm64 and ppc64
  used 'unsigned long long'. This change allows using a single integer
  type for uintptr_t across all architectures, and brings it into
  consistency with the rest of the code base, which generally uses
  'unsigned long' for memory addresses anyway. This change required
  fixing several assumptions about integer types in the arm code.
- Use _Bool as the boolean type. This is a specialized boolean type that
  was introduced in C99, and is preferrable over hacking booleans
  using integers. romcc sadly does not support _Bool, so for that we
  stick with the old uint8_t.
- Drop the least and fast integer types. They aren't used
  anywhere in the code base and are an unnecessary maintenance burden.
  Using the standard fixed width types is essentially always better anyway.
- Drop the UINT64_C() macro. It also isn't used anywhere and doesn't
  provide anything that a (uint64_t) cast doesn't.
- Implement the rest of the MIN and MAX numerical limits.
- Use static assertions to check that the integer widths are correct.
