Currently coreboot has limited use for the SMM save state. Typically
the only thing needed is to get or set a few registers and to know
which CPU triggered the SMI (typically via an IO write). Abstracting
away different SMM save states would allow to put some SMM
functionality like the SMMSTORE entry in common places.
To save place platforms can select different SMM save sate ops that
should be implemented. For instance AMD platforms don't need Intel SMM
save state handling.
Some platforms can encounter CPUs with different save states, which
the code then handles at runtime by comparing the SMM save state
revision which is located at the same offset for all SMM save state
types.

The ASEG smihandler bails out if an unsupported SMM save state

This also increases the loglevel when bailing out of SMM due to
unsupported SMM save state revision from BIOS_DEBUG to BIOS_WARNING,
given that the system likely still boots but won't have a functioning
smihandler.

Current implementation uses CPUID 0Bh function that returns the number

that this value doesn't change when HyperThreading is disabled (it's in
the Intel docs), so it breaks generate_cpu_entries().
- Use MSR 0x35 instead, which returns the correct number of logical
processors with and without HT.
- Rename the function to get_logical_cores_per_package, which is more
accurate.

This is required for Super I/Os to be able to read the CPU temperature
through PECI.
On 45nm Core 2 CPUs (Wolfdale, Yorkfield) it is not enabled by default.
This is probably related to erratum AW67 "Enabling PECI via the PECI_CTL
MSR incorrectly writes CPUID_FEATURE_MASK1 MSR". The suggested
workaround is "Do not initialize PECI before processor update is
loaded". Since coreboot performs microcode updates before running this
code it should not cause any trouble. It was tested on a Core 2 Duo
E8400, stepping E0.
PECI is already enabled by default on older (65nm) CPUs. Tested: Pentium
Dual-Core E2160.

Fix an issue the assembler didn't warn about to fix a crash on real

The linker uses the same address for variables in BSS if they aren't

Xeon-SP Skylake Scalable Processor can have 36 CPU threads (18 cores).
Current coreboot SMM is unable to handle more than ~32 CPU threads.
This patch introduces a version 2 of the SMM module loader which
addresses this problem. Having two versions of the SMM module loader
prevents any issues to current projects. Future Xeon-SP products will
be using this version of the SMM loader. Subsequent patches will
enable board specific functionality for Xeon-SP.
The reason for moving to version 2 is the state save area begins to
encroach upon the SMI handling code when more than 32 CPU threads are
in the system. This can cause system hangs, reboots, etc. The second
change is related to staggered entry points with simple near jumps. In
the current loader, near jumps will not work because the CPU is jumping
within the same code segment. In version 2, "far" address jumps are
necessary therefore protected mode must be enabled first. The SMM
layout and how the CPUs are staggered are documented in the code.
By making the modifications above, this allows the smm module loader to
expand easily as more CPU threads are added.

following in Kconfig.

Debug console will show all 36 cores relocated. Further tested by
generating SMI's to port 0xb2 using XDP/ITP HW debugger and ensured all
cores entering and exiting SMM properly. In addition, booted to Linux

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.

According to the comments of
https://review.coreboot.org/c/coreboot/+/41719
, which is about Microcode patch for amd/picasso.
Change the code with the same way.
The changes include:
1. combine the microcode_xxx.c and update_microcode.c
into one source.
2. Redefine the microcode updating function to eliminate
the parameter. Get the revision ID in the black box.
Reduce the depth of function calls.
3. Get the revision ID by bitwise calculation instead of
lookup table.
4. Reduce the confusing type casts.
5. Squash some lines.
We do not change the way it used to be. The code assume
only one microcode is integrated in CBFS. If needed in future,
41719 is the example of integrating multiple binaries.
And, 41719 depends on the definition in this patch.

The AMD64 Architecture Programmer's Manual, Volume 2: Systems
Programming says the following about variable MTRRs:
Variable Range Size and Alignment.
The size and alignment of variable memory-ranges (MTRRs) and I/O ranges
(IORRs) are restricted as follows:
* The boundary on which a variable range is aligned must be equal to the
range size. For example, a memory range of 16 Mbytes must be aligned on a
16-Mbyte boundary (i.e., naturally aligned).
* The range size must be a power of 2 (2^n , 52 > n > 11), with a minimum
allowable size of 4 Kbytes. For example, 4 Mbytes and 8 Mbytes are
allowable memory range sizes, but 6 Mbytes is not allowable.
Print out errors if these conditions are violated. I didn't assert since
`set_var_mtrr` can be used in boot block before the serial console is
enabled.

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.

- People sometimes have their editor auto-add themselves to files even

- Or they let the editor automatically update the copyright year,
because why not?
- Who is the copyright holder "The coreboot project Authors"?
- Or "Generated Code"?
Sidestep all these issues by simply not putting these notices in

LAPIC base is between smbase and smbase + smmsize. The size needs to
be available early so add them to the relocatable module parameters.
When the smmstub is used to relocate SMM the default SMM size 0x10000
is provided. On the permanent handler the size provided by
get_smm_info() is used.

FSP-T takes microcode pointer and location parameters, and FSP-T is
invoked before CAR is set-up and before memory is trained. So it is not
possible to modify supplied microcode pointer in runtime. Because of
that we have to hardcode the pointer in bootblock.
Also, current FSP-T on Xeons require microcode (it is not optional).
Reasons for that are currently unclear and are being investigated.
However for the present time we need to be able to add microcode at a
certain offset so FSP-T can be used.

This update is a combination of all four of the patches so that the
commit can be done without breaking parts of coreboot. This possible
breakage is because of the cross-dependencies between the original
separate patches would cause failure because of data structure changes.
security/intel/stm
This directory contains the functions that check and move the STM to the
MSEG, create its page tables, and create the BIOS resource list.
The STM page tables is a six page region located in the MSEG and are
pointed to by the CR3 Offset field in the MSEG header. The initial
page tables will identity map all memory between 0-4G. The STM starts
in IA32e mode, which requires page tables to exist at startup.
The BIOS resource list defines the resources that the SMI Handler is
allowed to access. This includes the SMM memory area where the SMI
handler resides and other resources such as I/O devices. The STM uses
the BIOS resource list to restrict the SMI handler's accesses.
The BIOS resource list is currently located in the same area as the
SMI handler. This location is shown in the comment section before
smm_load_module in smm_module_loader.c
Note: The files within security/intel/stm come directly from their
Tianocore counterparts. Unnecessary code has been removed and the
remaining code has been converted to meet coreboot coding requirements.

The current MP init timeout is hardcoded as 1s. To support
platform with many cpus, the timeout needs to be adjusted.
The number of cpus is calculated as:
number of sockets * number of cores per socket *
number of threads per core
How long the timeout should be set to, is heuristic.
It needs to be set long enough to ensure reboot stability,
but not unreasonable so that real failures can be detected
soon enough, especially for smaller systems.
This patch sets timeout to be minimum as 1 second, while each
cpu adds 0.1 second.

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.

Some platforms lack a non-eviction mode and therefore caching the
whole ROM to speed up XIP stages can be dangerous as it could result
in eviction if too much of the ROM is being accessed. The solution is
to only cache a region, about the size of the stage that the bootblock
is about to load: verstage and/or romstage.
TODO: now a limit of 256KiB is set for the total amount of cache that
can be used. This should fit most use cases for the time being.
