This change affects Intel CPUs only. As most platforms are doing
uCode update using FIT, they aren't affected by this code either.
Update microcode in MP-init using a single spinlock when running on
a Hyper-Threading enabled CPU on pre FIT platforms.
This will slow down the MP-init boot flow.
Intel SDM and various BWGs specify to use a semaphore to update
microcode on one thread per core on Hyper-Threading enabled CPUs.
Due to this complex code would be necessary to determine the core #ID,
initializing and picking the right semaphore out of CONFIG_MAX_CPUS / 2.
Instead use the existing global spinlock already present in MPinit code.
Assuming that only pre-FIT platforms with Hyper-Threading enabled and at
most 8 threads will ever run into this condition, the boot delay is
negligible.
This change is a counterproposal to the previous published patch series
being much more unsophisticated.

cbfs_region_load()) can be introduced later. It seems unnecessary to
keep carrying around "boot" in the names of most CBFS APIs if the vast
majority of accesses go to the boot CBFS (instead, more unusual
operations should have longer names that describe how they diverge from
the common ones).
cbfs_map() is paired with a new cbfs_unmap() to allow callers to cleanly
reap mappings when desired. A few new cbfs_unmap() calls are added to
generic code where it makes sense, but it seems unnecessary to introduce
this everywhere in platform or architecture specific code where the boot
medium is known to be memory-mapped anyway. In fact, even for
non-memory-mapped platforms, sometimes leaking a mapping to the CBFS
cache is a much cleaner solution than jumping through hoops to provide
some other storage for some long-lived file object, and it shouldn't be
outright forbidden when it makes sense.
Additionally, remove the type arguments from these function signatures.
The goal is to eventually remove type arguments for lookup from the
whole CBFS API. Filenames already uniquely identify CBFS files. The type
field is just informational, and there should be APIs to allow callers
to check it when desired, but it's not clear what we gain from forcing
this as a parameter into every single CBFS access when the vast majority
of the time it provides no additional value and is just clutter.

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.

msr_set_bit can only set single bits in MSRs and causes mixing of bit
positions and bitmasks in the MSR header files. Thus, replace the helper
by versions which can unset and set whole MSR bitmasks, just like the
"and-or"-helper, but in the way commit 64a6b6c was done (inversion done
in the helper). This helps keeping the MSR macros unified in bitmask
style.
In sum, the three helpers msr_set, msr_unset and msr_unset_and_set get
added.
The few uses of msr_set_bit have been replaced by the new version, while
the used macros have been converted accordingly.

Current implementation uses CPUID 0Bh function that returns the number
of logical cores of requested level. The problem with this approach is
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.
Tested on ThinkPad X220 with and without HT.

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

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.
TEST=build for Tiogapass platform under OCP mainboard. Enable the
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

The assumption up to this point was that if the system had an x86
processor, verstage would be running on the x86 processor. With running
verstage on the PSP, that assumption no longer holds true, so exclude
pieces of code that cause problems for verstage on the PSP.
This change will add these files to verstage only if the verstage
architecture is X86 - either 32 or 64 bit.

Most LAPIC registers are 32bit, and thus the use of long is valid on
x86_32, however it doesn't work on x86_64.
* Don't use long as it is 64bit on x86_64, which breaks interrupts
in QEMU and thus SeaBIOS wouldn't time out the boot menu
* Get rid of unused defines
* Get rid of unused atomic xchg code
Tested on QEMU Q35 with x86_64 enabled: Interrupts work again.

When Linux is booted, the kernel reports
"do_IRQ: 1.55 No irq handler for vector"
So far it comes with payloads SeaBIOS and depthcharge, not with
Grub. We assume Grub does something to avoid this problem.
AMD bug tracker system (JIRA PLAT-21393) says the APs can not be set
EXTINT delivery mode.
In Intel 64 and IA-32 Architectures Software Developer’s Manual volume
3A, see chapter 10.5.1 Local Vector Table, it says:
"The APIC architecture supports only one ExtINT source in a system,
usually contained in the compatibility bridge. Only one processor in the
system should have an LVT entry configured to use the ExtINT delivery
mode."
Tested on mandolin (Picasso) board, the error in dmesg is gone.
The bug 153677727 has two parts.
1. Soft lockup
2. do_IRQ 1.55.

2. Redefine the microcode updating function to eliminate

Reduce the depth of function calls.
3. Get the revision ID by bitwise calculation instead of

4. Reduce the confusing type casts.
5. Squash some lines.
We do not change the way it used to be. The code assume

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.

- Which incarnation of Google (Inc, LLC, ...) is the current

- People sometimes have their editor auto-add themselves to files even
though they only deleted stuff
- 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

This has nothing to do with the older, single-die Nehalem processors.

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.
