The (now removed) ID_SECTION_OFFSET=0x80 was actually the
secondary address flashrom and FILO are looking for. The
primary was 0x10, just below .reset.
If .id does not collide with .fit_pointer, use the higher
of the two locations.

For arch/arm[64], the offsets to board identification strings and
CONFIG_ROM_SIZE inside .id were never really used; it was only a
convenience to have the strings appear near the start of image.
Add the same strings in an uncompressed file in CBFS.

The strings in .id are expected to match the build for
the purpose of identifying the binary image. There is
no identified use for the offsets.
The files id.ld and prologue.inc were unused.

We have identical gdtptr16 and gdtptr. The reference in
gdtptr_offset calculation is not accounted for when
considering --gc-sections, so to support linking
gdt_init.S separately add dummy use of gdtptr symbol.
Realmode execution already accessed gdt that was located
outside [_start16bit,_estart16bit] region. Remove latter
symbol as the former was not really a start of region,
but entry point symbol.
With the romcc bootblock solution, entry32.inc may have
been linked into romstage before, but the !ENV_BOOTBLOCK
case seems obsolete now.

This change adds details about the memory map windows to translate
addresses between SPI flash space and host address space to coreboot
tables. This is useful for payloads to setup the translation using the
decode windows already known to coreboot. Until now, there was a
single decode window at the top of 4G used by all x86
platforms. However, going forward, platforms might support more decode
windows and hence in order to avoid duplication in payloads this
information is filled in coreboot tables.
`lb_spi_flash()` is updated to fill in the details about these windows
by making a call to `spi_flash_get_mmap_windows()` which is
implemented by the driver providing the boot media mapping device.

The initial bootblock assembly code on x86 is just put into the .text
section, which just happens to come before all the individual .text.*
function sections in the program.ld script. So it tends to be at the
start of the image, but if you inserted another linker script section
with contents before .text, it would cause a problem. (I'm not sure if
it's an architectural requirement for _start16bit to come at the start
of the image, but at least its 4K alignment requirement would waste a
lot of space if it didn't.)
This patch moves the section to .text._start which is the name other
architectures use for the code they want in the very front of the image
and which is listed first in program.ld.

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.

having a normal DECLARE_REGION() in <symbols.h> and then an extra
DECLARE_OPTIONAL_REGION() in the C file using it, you just say
DECLARE_OPTIONAL_REGION() directly in <symbols.h> (in place and instead
of the usual DECLARE_REGION()). This basically looks the same way in the

The GDT loading did work fine on x86_64 a few months ago, but today it
only works in QEMU, but not on real hardware or KVM-enabled QEMU. This
might be related to toolchain changes.
Use 64bit GDT loading on x86_64 and force the assembler to generate a
64bit address load on the GDT. This will make sure no 32bit (signed)
displacement op is being generated, which points to the wrong address
in longmode.
Verified using readelf and made sure no R_X86_64_32S relocation symbol
is emitted. Disassembled the romstage ELF and made sure the GDT address
is 64bit in size.
Tested on QEMU and KVM-enabled QEMU: Doesn't crash any more on KVM.

Compiler's instrumentation cannot insert asan memory checks in
case of memory functions like memset, memcpy and memmove as they
are written in assembly.
So, we need to manually check the memory state before performing
each of these operations to ensure that ASan is triggered in case
of bad access.

The `GetPhysicallyInstalledSystemMemory` API call, at least on Windows
10, returns an error if SMBIOS tables are invalid. Various tools use
this API call and don't operate correctly if this fails. For example,
the "Intel Processor Diagnostic Tool" program is affected.
Windows then guesses the physical memory size by accumulating entries
from the firmware-provided memory map, which results in a total memory
size that is slightly lower than the actual installed memory capacity.
To fix this issue, add the handle to a type 16 entry to all type 17
entries.
Add new fields to struct memory_info and fill them in Intel common code.
Use the introduced variables to fill type 16 in smbios.c and provide
a handle to type 17 entries.
Besides keeping the current behaviour on intel/soc/common platforms, the
type 16 table is also emitted on platforms that don't explicitly fill
it, by using the existing fields of struct memory_info.
Tested on Windows 10:
The GetPhysicallyInstalledSystemMemory API call doesn't return an error
anymore and the installed memory is now being reported as 8192 MiB.

The tlbimvaa operation (invalidate unified TLB by MVA, all address
space identifiers) is only available on armv7 processors that support
Multiprocessing Extensions. When used on processors that do not support
the extensions it causes an "undefined instruction" exception.
This patch changes the MMU table entry filling code to use the tlbimva
(invalidate unified TLB entry by MVA and address space identifier)
operation for invalidating TLB entries, which is supported on all armv7
processors.
As address space identifiers are not used in TLB entries in coreboot
(all entries are set as global), these two operations can safely be
used interchangeably. The ASID value supplied to the operation is not
checked for global TLB entries.
More information as well as the data formats for the tlbimvaa and
tlbimva operations are detailed in the "ARM Architecture Reference
Manual ARMv7-A" edition, issue "C.c" page B4-1747.

Kconfig 4.17 started using the $(..) syntax for environment variable
expansion while we want to keep expansion to the build system.
Older Kconfig versions (like ours) simply drop the escapes, not
changing the behavior.
While we could let Kconfig expand some of the variables, that only
splits the handling in two places, making debugging harder and
potentially messing with reproducible builds (e.g. when paths end up
in configs), so escape them all.

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.
As a generalization, remove all-y for CONFIG_ARCH_xx guarded
makefiles.

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.

Builds where RESET_X86_VECTOR is adjusted would create unintentionally
large bootblock files since id section can move far away from .reset
and .text. Some builds segfault or may try to create close to 4 GB
large intermediate build objects.
For cases where build is successful, id section would not reside within
REGION(program) or REGION(bootblock).
A proper fix to always place the ID data at the end of the coreboot.rom
file is left as follow-up work. For now, just place id section below
.reset.
