Bootguard sets up CAR/NEM on its own so the only thing needed is to
find free MTRRs for our own CAR region and clear that area to fill in
cache lines.
TESTED on prodrive/hermes with bootguard enabled.

Tested on HP 280 G2, SMMSTORE v1 and v2 still work.
Other tests:
- If one does not set BIOS_CONTROL bit WPD, SMMSTORE breaks.
- If one does not write the magic MSR `or 1`, SMMSTORE breaks.

The `location` member of `struct boot_state_callback` is conditionally
guarded depending on `CONFIG(DEBUG_BOOT_STATE)` using preprocessor. It
is probably intended to save some space when the `location` strings do
not get printed. However, directly using the `location` member without
any guards will cause a compile-time error. Plus, preprocessor-guarded
code gets nasty really quickly.
In order to minimise preprocessor usage, introduce the `bscb_location`
inline helper function, which transforms the compile-time error into a
link-time error. It is then possible to substitute preprocessor guards
with an ordinary C `if` statement.

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.

Over the last couple of years we have continuously added more and more
CBMEM init hooks related to different independent components. One
disadvantage of the API is that it can not model any dependencies
between the different hooks, and their order is essentially undefined
(based on link order). For most hooks this is not a problem, and in fact
it's probably not a bad thing to discourage implicit dependencies
between unrelated components like this... but one resource the
components obviously all share is CBMEM, and since many CBMEM init hooks
are used to create new CBMEM areas, the arbitrary order means that the
order of these areas becomes unpredictable.
Generally code using CBMEM should not care where exactly an area is
allocated, but one exception is the persistent CBMEM console which
relies (on a best effort basis) on always getting allocated at the same
address on every boot. This is, technically, a hack, but it's a pretty
harmless hack that has served us reasonably well so far and would be
difficult to realize in a more robust way (without adding a lot of new
infrastructure). Most of the time, coreboot will allocate the same CBMEM
areas in the same order with the same sizes on every boot, and this all
kinda works out (and since it's only a debug console, we don't need to
be afraid of the odd one-in-a-million edge case breaking it).
But one reproducible difference we can have between boots is the vboot
boot mode (e.g. normal vs. recovery boot), and we had just kinda gotten
lucky in the past that we didn't have differences in CBMEM allocations
in different boot modes. With the recent addition of the RW_MCACHE
(which does not get allocated in recovery mode), this is no longer true,
and as a result CBMEM consoles can no longer persist between normal and
recovery modes.
The somewhat kludgy but simple solution is to just create a new class of
specifically "early" CBMEM init hooks that will always run before all
the others. While arbitrarily partitioning hooks into "early" and "not
early" without any precise definition of what these things mean may seem
a bit haphazard, I think it will be good enough in practice for the very
few cases where this matters and beats building anything much more
complicated (FWIW Linux has been doing something similar for years with
device suspend/resume ordering). Since the current use case only relates
to CBMEM allocation ordering and you can only really be "first" if you
allocate in romstage, the "early" hook is only available in romstage for
now (could be expanded later if we find a use case for it).

With the introduction of fw_config support in coreboot, it is possible
for mainboards to control the state of a device (on/off) in ramstage
using fw_config probe conditions. However, the device tree in
immutable in all other stages and hence `is_dev_enabled()` does not
really reflect the true state as in ramstage.
This change adds a call to `fw_config_probe_dev()` in
`is_dev_enabled()` when device tree is immutable (by checking
DEVTREE_EARLY) to first check if device is disabled because of device
probe conditions. If so, then it reports device as being
disabled. Else, dev->enabled is used to report the device state.
This allows early stages (bootblock, romstage) to use
`is_dev_enabled()` to get the true state of the device by taking probe
conditions into account and eliminates the need for each caller to
perform their own separate probing.

This change adds a helper function `fw_config_probe_dev()` that allows
the caller to check if any of the probe conditions are true for any
given device. If device has no probe conditions or a matching probe
condition, then it returns true and provides the matching probe
condition back to caller (if provided with a valid pointer). Else, it
returns false. When fw_config support is disabled, this function
always returns true.

module google/volteer increased to above 64K in size, and thus failed to

pulled into the SMM build because of elog, which calls
`pci_dev_is_wake_source`, and is the only user of `struct device` in
SMM. Changing this function to take a pci_devfn_t instead allows the
linker to remove almost the entire devicetree from SMM (only usage left
is when disabling HECI via SMM).

The existing helpers for reading/writing MSRs (rdmsr, wrmsr) require use
of the struct `msr_t`, which splits the MSR value into two 32 bit parts.
In many cases, where simple 32 bit or 64 bit values are written, this
bloats the code by unnecessarly having to use that struct.
Thus, introduce the helpers `msr_read` and `msr_write`, which take or
return `uint64_t` values, so the code condenses to a single line or two,
without having to deal with `msr_t`.
Example 1:
~~~
msr_t msr = {
.lo = read32((void *)(uintptr_t)0xfed30880),
.hi = 0,
};
msr.lo |= 1;
wrmsr(0x123, msr);
~~~
becomes
~~~
uint32_t foo = read32((void *)(uintptr_t)0xfed30880);
msr_write(0x123, foo | 1)
~~~
Example 2:
~~~
msr_t msr = rdmsr(0xff);
uint64_t msr_val = (msr.hi << 32) | msr.lo;
~~~
becomes
~~~
uint64_t msr_val = msr_read(0xff);
~~~

This adds full EINJ support with trigger action tables. The actual
error injection functionality is HW specific. Therefore, HW specific
code should call acpi_create_einj with an address where action table
resides. The default params of the action table are filled out by the
common code. Control is then returned back to the caller to modify or
override default parameters. If no changes are needed, caller can
simply add the acpi table. At runtime, FW is responsible for filling
out the action table with the proper entries. The action table memory
is shared between FW and OS. This memory should be marked as reserved
in E820 table.
Tested on Deltalake mainboard. Boot to OS, load the EINJ driver (
modprobe EINJ) and verify EINJ memory entries are in /proc/iomem.
Further tested by injecting errors via the APEI file nodes. More
information on error injection can be referenced in the latest ACPI
spec.

The {get,set}_option() functions are not type-safe: they take a pointer
to void, without an associated length/size. Moreover, cmos_get_option()
does not always fully initialise the destination value (it has no means
to know how large it is), which can cause issues if the caller does not
initialise the value beforehand.
The idea behind this patch series is to replace the current type-unsafe
API with a type-safe equivalent, and ultimately decouple the option API
from CMOS. This would allow using different storage mechanisms with the
same option system, maximising flexibility.
Most, if not all users of get_option() have a value to fall back to, in
case the option could not be read. Thus, get_int_option() takes a value

We had the addrspace_32bit rdev in prog_loaders.c for a while to help
represent memory ranges as an rdev, and we've found it useful for a
couple of things that have nothing to do with program loading. This
patch moves the concept straight into commonlib/region.c so it is no
longer anchored in such a weird place, and easier to use in unit tests.
Also expand the concept to the whole address space (there's no real need
to restrict it to 32 bits in 64-bit environments) and introduce an
rdev_chain_mem() helper function to make it a bit easier to use. Replace
some direct uses of struct mem_region_device with this new API where it
seems to make sense.

Use the same stack location during relocation as for the permanent
handler.
When the number of CPUs is too large the stacks during relocation
don't fit inside the default SMRAM segment at 0x30000. Currently the
code would just let the CPU stack base grow downwards outside of the
default SMM segment which would corrupt lower memory if S3 is
implemented.
Also update the comment on smm_module_setup_stub().

CBFS_VERIFICATION requires the CBFS metadata hash anchor to be linked
into an uncompressed stage, but for platforms using COMPRESS_BOOTBLOCK,
this is only the decompressor stage. The first CBFS accesses are made in
the bootblock stage after decompression, so if we want to make
CBFS_VERIFICATION work on those platforms, we have to pass the metadata
hash anchor from the decompressor into the bootblock. This patch does
just that. (Note that this relies on the decompressor data remaining
valid in memory for as long as the metadata hash anchor is needed. This
is always true even for OVERLAP_DECOMPRESSOR_ROMSTAGE() situations
because the FMAP and CBFS metadata necessarily need to have finished
verification before a new stage could be loaded.)

Right before CB:49334 was submitted, I changed the signature of
cbfs_allocator_t function pointers to include another argument passing
in the already loaded CBFS metadata (to allow for the rare edge case of
allocators needing to read CBFS attributes). This interface is not meant
to be able to modify the passed-in metadata, so to clarify that and
prevent potential errors, we should declare the argument const.

This commit introduces set of package closing functions corresponding
with their opening function names. For example acpigen_write_if()
opens if-statement package, acpigen_write_if_end() closes it.
Now acpigen_write_else() closes previously opened acpigen_write_if(),
so acpigen_pop_len() is not required before it.
