APs use a lot less stack, so set up a separate stack for those in .bss.
Now that CPU_INFO_V2 is the only code path that is used, there is no
need to align stacks in c_start.S.

It's hidden behind the configuration option `CONFIG_ROMSTAGE_LIBHWBASE'.
This also adds some glue code to use the coreboot console for debug
output and our monotonic timer framework as timer backend.
Running Ada code in romstage and more particular libhwbase brings a few
challenges as global initialized variables are not supported in
Cache-As-Ram mode.
1. The libhwbase dynamic mmio driver implementation makes the Gnat
compiler generate some global initialized variables.
For this reason, when compiled for romstage or for romstage and
ramstage the static mmio driver is enforced (`HWBASE_STATIC_MMIO').
2. The Gnat compiler generates elaboration functions to initialize
program data at runtime. These elaboration functions are called by
the romstage_adainit() function.
The data references symbols suffixed by `_E'. Even though these
symbols, at compilation time, do not contain any data and are
filled with zeros, the Gnat compiler installs them in the .data
section.
Since these symbols are actually filled with zeros, it is safe to
install them in the .bss section.
cf. https://docs.adacore.com/gnat_ugn-docs/html/gnat_ugn/gnat_ugn/elaboration_order_handling_in_gnat.html#elaboration-code

This reverts commit 095c931cf12924da9011b47aa64f4a6f11d89f13.
Previously cpu_info() was implemented with a struct on top of an
aligned stack. As FSP changed the stack value cpu_info() could not be
used in FSP context (which PPI is). Now cpu_info() uses GDT segments,
which FSP does not touch so it can be used.
This also exports cpu_infos from cpu.c as it's a convenient way to get
the struct device * for a certain index.
TESTED on aldrvp: FSP-S works and is able to run code on APs.

This disables MP table generation for the affected boards
since interrupt routing entries would now be completely missing.
The mechanism itself is flawed and redundant. The mapping
of integrated PCI devices' INTx pins to IOAPIC pins is
dependent of configuration registers and needs not appear
in the devicetree.cb files at all.
The write_smp_table implementation would skip writing
any entry delivering to destination IOAPIC ID 0. This
does not follow MP table specification.
There were duplicate calls to register_new_ioapic_gsi0(),
with another present under southbridge LPC device.

gcc12+ will require riscv architecture selection to come not only with
featurei suffixd charactersa, it also comes with feature_ful suffix_ed
words_mith. Much creative, very appreciate.
To accommodate for this madness, enable the already existing (but off by
default) support for that in our gcc11 build, support using by detecting
the compiler's behavior in xcompile and pass that knowledge along to our
build system.
Then cross our fingers and hope for the best!

Clear the SMBIOS region before writing SMBIOS tables.
On librem_mini and librem_mini_v2, CBMEM allocations are offset by 4K
for reboots relative to the cold boot. This means the unused SMBIOS
region could contain the first 4K of the ACPI tables from the last boot
(including the signature), which prevents Linux from booting.
The CBMEM 4K offset appears to be due to FSP allocating memory
differently between cold boot and reboot, this appears to be normal and
causes the CBMEM base address to change.
It is not clear why Linux examines an ACPI signature found in this
region, but boot logs over serial confirm that it sees the corrupt
table. The table is supposed to be found just below 1M, and kernel
source appears to look in this region, but it is definitely finding the
corrupt table in CBMEM.
Normal cold boot:
[ 0.008615] ACPI: RSDP 0x00000000000F6190 000024 (v02 COREv4)
[ 0.008619] ACPI: XSDT 0x0000000099B480E0 00005C (v01 COREv4 COREBOOT 00000000 CORE 20220331)

There are no specific errors but it returns to the firmware soon after,
presumably due to a fault. This appears to be so early in the boot
that panic=0 on the kernel command line has no effect.

Since there are many identifiers whose name contain "__unused" in
headers of musl libc, introducing a macro which expands "__unused" to
the source of a util may have disastrous effect during its compiling
under a musl-based platform.
However, it is hard to detect musl at build time as musl is notorious
for having explicitly been refusing to add a macro like "__MUSL__" to
announce its own presence.
Using __always_unused and __maybe_unused for everything may be a good
idea. This is how it works in the Linux kernel, so that would at least
make us match some other standard rather than doing our own thing
(especially since the other compiler.h shorthand macros are also
inspired by Linux).

This patch contains several minor cleanups related to compiler.h:
- Replace __always_unused() (which is a Linux-specific concept that
doesn't make sense without also having __maybe_unused(), and had zero
uses in the codebase) with __unused() which moves here from helpers.h
- Add __underscores__ to the names of all attributes in the compiler
attribute shorthand macros. This is necessary to make them work in
files where the same name was already used for an identifier (e.g.
cbfstool/cbfs.h's `unused` array of file types).
- Remove libpayload's own copy of compiler.h and make it directly pull
in the commonlib/bsd copy.

* visible opt-in flag to allow experimenting
Clang seems to work rather well on x86_32 so it makes sense to start

This allows abuild to differentiate between targets that are known to

With CBFS verification, cbfstool (CB:41121) needs bootblock to be
present in coreboot.pre in order to locate the metadata hash stored in
it. Therefore we have to ensure that bootblock is added to CBFS before
other CBFS files are added.
To solve the problem, create the 'add_bootblock' function, and call it
in the coreboot.pre recipe. Because bootblock.bin is now a prerequisite
of coreboot.pre, it will get built even if CONFIG_BOOTBLOCK_IN_CBFS=n.

AGESA has a lot of code in the .data section (initialized data). However
there is no such section in CAR stages as the code runs in XIP mode and
CAR is too small to contain the data section. When the linker can not
match code to a section it will just append it, which is why AGESA
worked at all.
Follow-up patches will attempt to fix AGESA and set Kconfig parameter to
'n'. After all AGESA sources have been fixed, this can be removed.

Now that the bootblock isn't added to cbfs anymore, on some targets it's
only conditionally build. One example would be Intel APL where it only
gets build when stitched into an IFWI. This is always done when
compiling for real targets but not by the CI builder. This adds a dummy
target to make sure the bootblock always gets buildtested.

This commit adds support for catching null dereferences and execution
through x86's debug registers. This is particularly useful when running
32-bit coreboot as paging is not enabled to catch these through page

DEBUG_HW_BREAKPOINTS, DEBUG_NULL_DEREF_BREAKPOINTS and
DEBUG_NULL_DEREF_HALT.

Some platforms don't need a top aligned bootblock in cbfs like Intel
APL or modern AMD platforms as the bootblock is loaded differently.
So they don't need the top aligned cbfs bootblock.

The makefiles don't like cbfs file names with spaces in them so update
the file name with '_' instead of spaces. To keep the master header at
the top of cbfs, add a placeholder.
This removes the need to handle the cbfs master header in cbfstool.
This functionality will be dropped in a later CL.
On x86 reserve some space in the linker script to add the pointer.
On non-x86 generate a pointer inside a C struct file.
As a bonus this would actually fix the master header pointer mechanism
on Intel/APL as only the bootblock inside IFWI gets memory mapped.
TESTED on thinkpad X201: SeaBIOS correctly finds the cbfs master
header.

The printed address ranges in the tree (resource allocator and even
some MTRR code) usually shows the range inclusive (meaning from start
address to the real end address of the range). Though there is still
some code in the MTRR context which prints the ranges with an exclusive
end. This patch aligns the printing of ranges in the MTRR code to be
consistent among the tree so that the shown end addresses are now
inclusive.

This patch aims to make timestamps more consistent in naming,
to follow one pattern. Until now there were many naming patterns:
- TS_START_*/TS_END_*
- TS_BEFORE_*/TS_AFTER_*
- TS_*_START/TS_*_END
This change also aims to indicate, that these timestamps can be used
to create time-ranges, e.g. from TS_BOOTBLOCK_START to TS_BOOTBLOCK_END.
