Selecting CPU_X86_CACHE_HELPER only added the x86_enable_cache wrapper
function around enable_cache which additionally wrote a POST code to
port 0x80 and printed a message to the console. This function was only
called during multi-processor initialization in ramstage via the init
function pointer in the CPU's device operations struct and was run on
all cores, so the message on the console was printed once per CPU core.
This patch replaces all x86_enable_cache calls by calls to enable_cache
and removes the wrapper function and the Kconfig symbol
CPU_X86_CACHE_HELPER which was used to only add this when the
corresponding CPUs used the x86_enable_cache wrapper function.

Since all x86 CPUs in tree have MTRR support, there is no need to guard
the DISPLAY_MTRRS option with HAVE_DISPLAY_MTRRS. Also all x86 CPUs/SoCs
have a display_mtrrs call at least somewhere in their code, so selecting
the DISPLAY_MTRRS option will always have an effect. All SoCs that don't
select RESET_VECTOR_IN_RAM have the postcar stage where it gets called.
The two AMD SoCs that select RESET_VECTOR_IN_RAM use the FSP2 driver
which contains plenty of display_mtrrs calls.

With using a Kconfig option to add the x86 LAPIC support code to the
build, there's no need for adding the corresponding directory to subdirs
in the CPU/SoC Makefile. Comparing which CPU/SoC Makefiles added
(cpu/)x86/mtrr and (cpu/)x86/lapic before this and the corresponding
MTRR code selection patch and having verified that all platforms
added the MTRR code on that patch shows that soc/example/min86 and
soc/intel/quark are the only platforms that don't end up selecting the
LAPIC code. So for now the default value of CPU_X86_LAPIC is chosen as y
which gets overridden to n in the Kconfig of the two SoCs mentioned
above.

All x86-based CPUs and SoCs in the coreboot tree end up including the
Makefile in cpu/x86/mtrr, so include this directly in the Makefile in
cpu/x86 to add it for all x86 CPUs/SoCs. In the unlikely case that a new
x86 CPU/SoC will be added, a CPU_X86_MTRR Kconfig option that is
selected be default could be added and the new CPU/SoC without MTRR
support can override this option that then will be used in the Makefile
to guard adding the Makefile from the cpu/x86/mtrr sub-directory.
In cpu/intel all models except model 2065X and 206AX are selcted by a
socket and rely on the socket's Makefile.inc to add x86/mtrr to the
subdirs, so those models don't add x86/mtrr themselves. The Intel
Broadwell SoC selects CPU_INTEL_HASWELL and which added x86/mtrr to the
subdirs. The Intel Xeon SP SoC directory contains two sub-folders for
different versions or generations which both add x86/mtrr to the subdirs
in their Makefiles.

function gets renamed to do_mp_init_with_smm and a new mp_init_with_smm
function is created which then calls do_mp_init_with_smm, prints the
error if it didn't return CB_SUCCESS and passes the return value of
do_mp_init_with_smm to its caller.
Since no CPU/SoC code handles a mp_init_with_smm failure apart from
printing a message, also add a comment at the mp_init_with_smm call
sites that the code might want to handle a failure.

There are two possible code sections where the cpu_info macros can be

Doing a `push %eax` while in a .code64 section will result in a compiler
error. This macro manually pushes the 32-bit register onto the stack so
we can share the code between 32 and 64 bit builds.
We also can't implicitly dereference per_cpu_segment_selector because
it's a 32-bit address. Trying to do this results in the following:
E: Invalid reloc type: 11
E: Illegal use of 32bit sign extended addressing at offset 0x1b2
If we load the address first, then dereference it, we can work around
the limitation.

There is currently a fundamental flaw in the current cpu_info()
implementation. It assumes that current stack is CONFIG_STACK_SIZE
aligned. This assumption breaks down when performing SMM relocation.
The first step in performing SMM relocation is changing the SMBASE. This
is accomplished by installing the smmstub at 0x00038000, which is the
default SMM entry point. The stub is configured to set up a new stack
with the size of 1 KiB (CONFIG_SMM_STUB_STACK_SIZE), and an entry point
of smm_do_relocation located in RAMSTAGE RAM.
This means that when smm_do_relocation is executed, it is running in SMM
with a different sized stack. When cpu_info() gets called it will be
using CONFIG_STACK_SIZE to calculate the location of the cpu_info
struct. This results in reading random memory. Since cpu_info() has to
run in multiple environments, we can't use a compile time constant to
locate the cpu_info struct.
This CL introduces a new way of locating cpu_info. It uses a per-cpu
segment descriptor that points to a per-cpu segment that is allocated on
the stack. By using a segment descriptor to point to the per-cpu data,
we no longer need to calculate the location of the cpu_info struct. This
has the following advantages:
* Stacks no longer need to be CONFIG_STACK_SIZE aligned.
* Accessing an unconfigured segment will result in an exception. This
ensures no one can call cpu_info() from an unsupported environment.
* Segment selectors are cleared when entering SMM and restored when
leaving SMM.
* There is a 1:1 mapping between cpu and cpu_info. When using
COOP_MULTITASKING, a new cpu_info is currently allocated at the top of
each thread's stack. This no longer needs to happen.
This CL guards most of the code with CONFIG(CPU_INFO_V2). I did this so
reviewers can feel more comfortable knowing most of the CL is a no-op. I
would eventually like to remove most of the guards though.
This CL does not touch the LEGACY_SMP_INIT code path. I don't have any
way of testing it.
The %gs segment was chosen over the %fs segment because it's what the
linux kernel uses for per-cpu data in x86_64 mode.

The %fs and %gs segment are typically used to implement thread local
storage or cpu local storage. We don't currently use these in coreboot,
so there is no reason to map them. By setting the segment index to 0,
it disables the segment. If an instruction tries to read from one of
these segments an exception will be raised.
The end goal is to make cpu_info() use the %gs segment. This will remove
the stack alignment requirements and fix smm_do_relocation.

This fixes a hard to debug hang that could occur in any stage, but in
the end it follows simple rules and is easy to fix.
In long mode the 32bit displacement addressing used on 'mov' and 'lea'
instructions is sign-extended. Those instructions can be found using
readelf on the stage and searching for relocation type R_X86_64_32S.
The sign extension is no issue when either running in protected mode or
the code module and thus the address is below 2GiB. If the address is
greater than 2GiB, as usually the case for code in TSEG, the higher
address bits [64:32] are all set to 1 and the effective address is
pointing to memory not paged. Accessing this memory will cause a page
fault, which isn't handled either.
To prevent such problems
- disable R_AMD64_32S relocations in rmodtool
- add comment explaining why it's not allowed
- use the pseudo op movabs, which doesn't use 32bit displacement addressing
- Print a useful error message if such a reloc is present in the code

Allows compile-time optimisation on platforms that do not wish
to enable runtime checking of X2APIC.
Legacy lapic_cpu_init() is incompatible so there is dependency
on PARALLEL_MP. Also stop_this_cpu() is incompatible, so there
is dependency on !AP_IN_SIPI_WAIT.
Since the code actually lacks enablement of X2APIC (apparently
assuming the blob has done it) and the other small flaws pointed
out in earlier reviews, X2APIC_RUNTIME is not selected per
default on any platform yet.

Some platforms which have large amounts of RAM and also write-combining
regions may decide to drop the WC regions in favor of the default when
preserving MTRRs for the OS. From a data safety perspective, this is
safe to do, but if, say, the graphics framebuffer is the region that is
changed from WC to UC/WB, then the performance of writing to the
framebuffer will decrease dramatically.
Modern OSes typically use Page Attribute Tables (PAT) to determine the
cacheability on a page level and usually do not touch the MTRRs. Thus,
it is believed to be safe to stop reserving MTRRs for the OS, in
general; PentiumII is the exception here in that OSes that still
support that may still require MTRRs to be available. In any case, if
the OS wants to reprogram all of the MTRRs, it is of course still free
to do so (after consulting the e820 table).

With CBnT a digest needs to be made of the IBB, Initial BootBlock, in
this case the bootblock. After that a pointer to the BPM, Boot Policy
Manifest, containing the IBB digest needs to be added to the FIT
table.
If the fit table is inside the IBB, updating it with a pointer to the
BPM, would make the digest invalid.
The proper solution is to move the FIT table out of the bootblock.
The FIT table itself does not need to be covered by the digest as it
just contains pointers to structures that can by verified by the
hardware itself, such as microcode and ACMs (Authenticated Code
Modules).

if we know that the "device" is always just memory. This patch changes
it to be represented by a simple pointer and size. Since some code still
really wants this to be an rdev, introduce a prog_chain_rdev() helper to

CB:49896 added support in `intel_microcode_find()` to cache the found
microcode for faster subsequent accesses. This works okay when the
function succeeds in finding the microcode on BSP. However, if for any
reason, `cpu_microcode_blob.bin` does not contain a valid microcode
for the given processor, then the logic ends up attempting to find
microcode again and again every time it is called (because
`ucode_updates` is set to NULL on failed find, thus retriggering the
whole find sequence every time). This leads to a weird race condition
when multiple APs are running in parallel and executing this
function.
A snippet of the issues observed in the scenario described above:
```
...
microcode: Update skipped, already up-to-date
...
Microcode header corrupted!
...
```
1. AP reports that microcode update is being skipped since the current
version matches the version in CBFS (even though there is no matching
microcode update in CBFS).
2. AP reports microcode header is corrupted because it thinks that the
data size reported in the microcode is larger than the file read from
CBFS.
Above issues occur because each time an AP calls
`intel_microcode_find()`, it might end up seeing some intermittent
state of `ucode_updates` and taking incorrect action.
This change fixes this race condition by separating the logic for
finding microcode into an internal function `find_cbfs_microcode()`
and maintaining the caching logic in `intel_microcode_find()` using a
boolean flag `microcode_checked`.
BUG=b:182232187
TEST=Verified that `intel_microcode_find()` no longer makes repeated
attempts to find microcode from CBFS if it failed the first time.

both the traditional and ULT variants of Broadwell, because the CPU

Without this patch, Broadwell CPUs would hang when trying to print the

This was missed in commit f542b7bcef (cpu/intel/haswell: Add Broadwell

were done with flashconsole enabled, which somehow boots properly even
though the console time tracking would not work (depends on TSC).

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.

This patch renames cbfs_boot_map_with_leak() and cbfs_boot_load_file()
to cbfs_map() and cbfs_load() respectively. This is supposed to be the
start of a new, better organized CBFS API where the most common
operations have the most simple and straight-forward names. Less
commonly used variants of these operations (e.g. cbfs_ro_load() or
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.
