In CB:41119, I sort of made up a mechanism on the fly for how to make
the machine-parseable cbfstool print output extensible without breaking
backwards compatibility for older scripts. But I only explained it in
the commit message which is not very visible. This patch adds a comment
to the function that generates that output so that people who want to
change it can understand the intent.

This reverts commit 89b4f69746.
SI_BIOS is mostly used to indicate the BIOS region in Intel IFD. Not all
platforms are Intel platforms with an IFD, so revert this change. Also
tooling often depends on names not changing so renaming things should
not be done lightly. The default region should also be in sync with
non-x86 and made systematic across the tree.

Currently ifdtool --validate will not correctly validate the FMAP
against the IFD regions, since it will compare the IFD bios region with
an FMAP region called SI_BIOS.
It's probably a good idea to define default name for the BIOS FMAP
region like we have for 'COREBOOT' or 'FMAP' FMAP region.

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

Currently elogtool sub-proccesses flashrom as calling libflashrom
requires a missing function from the previous flashrom release.
Pending a new release of flashrom we must continue to use subprocess.
However the current subprocess wrapper implementation lives in
vboot_reference which is a git sub-module of coreboot. This causes
all sorts of grief keeping a subprocess ABI stable from vboot_reference
when the rest of vboot_reference builds of HEAD of the flashrom tree
(i.e., using unreleased libflashrom functions). In order to not keep
finding ourseleves in a bind between the two separately moving trees
with different build environments, decouple elogtool with its own

The Intel Firmware Interface Table (FIT) is a bit of an annoying outlier
among CBFS files because it gets manipulated by a separate utility
(ifittool) after cbfstool has already added it to the image. This will
break file hashes created for CBFS verification.
This is not actually a problem when booting, since coreboot never
actually loads the FIT from CBFS -- instead, it's only in the image for
use by platform-specific mechanisms that run before coreboot's
bootblock. But having an invalid file hash in the CBFS image is
confusing when you want to verify that the image is correctly built for
verification.
This patch adds a new CBFS file type "intel_fit" which is only used for
the intel_fit (and intel_fit_ts, if applicable) file containing the FIT.
cbfstool will avoid generating and verifying file hashes for this type,
like it already does for the "bootblock" and "cbfs header" types. (Note
that this means that any attempt to use the CBFS API to actually access
this file from coreboot will result in a verification error when CBFS
verification is enabled.)

RSDP in Linux (UEFI, Kexec, Legacy/BIOS). Some UEFI zealots are
threatening that legacy code will be removed from Linux so it's best
to already adapt to that possibility.
Tested on Qemu:
- With qemu the RSDP is always in the EBDA, so checking if Linux uses
the provided pointer is better done with a forced bad entry
- With a fake bad pointer Linux correctly does not find RDSP

cb_err_t was meant to be used in place of `enum cb_err` in all
situations, but the choice to use a typedef here seems to be
controversial. We should not be arbitrarily using two different
identifiers for the same thing across the codebase, so since there are
no use cases for serializing enum cb_err at the moment (which would be
the primary reason to typedef a fixed-width integer instead), remove
cb_err_t again for now.

This reverts commit d74b8d9c99.
This change breaks the 'make all' build of the cbfstool tools
from the util/cbfstool directory unless libflashrom-dev is
installed, complaining that flashrom is not installed.
Even with libflashrom-dev installed, it breaks building
elogtool with the public version of libflashrom-dev.

The whole point of moving do_cbfs_locate() later (CB:59877) was that it
could use the file size that is actually going to be inserted into CBFS,
rather than the on-disk file size. Unfortunately, after all that work I
forgot to actually make it do that. This patch fixes that.
Since there is no more use case for do_cbfs_locate() having to figure
out the file size on its own, and that generally seems to be a bad idea
(as the original issue shows), also remove that part of it completely
and make the data_size parameter mandatory.

In cbfs_add_component(), the |offset| variable confusingly jumps back
and forth between host address space and flash address space in some
cases. This patch tries to clean that logic up a bit by converting it
to flash address space very early in the function, and then keeping it
that way afterwards. convert() implementations that need the host
address space value should store it in a different variable to reduce
the risk of confusion. This should also fix a tiny issue where
--gen-attribute might have previously encoded the base address as given
in CBFS -- it probably makes more sense to always have it store a
consistent format (i.e. always flash address).
Also revert the unnecessary check for --base-address in
add_topswap_bootblock() that was added in CB:59877. On closer
inspection, the function actually doesn't use the passed in *offset at
all and uses it purely as an out-parameter. So while our current
Makefile does pass --base-address when adding the bootblock, it actually
has no effect and is redundant for the topswap case.

The placement calculation logic in cbfs_add_component() has become quite
a mess, and this patch can only fix that to a limited degree. The
interaction between all the different pathways of how the `offset`
variable can be set and at what point exactly the final placement offset
is decided can get quite convoluted. In particular, one existing problem
is that the offset for a file added with the --align flag is decided
before the convert() function is called, which may change the form (and
thereby the size) of the file again after its location was found --
resulting in a location that ends up being too small, or being unable to
find a location for a file that should fit. This used to be okay under
the assumption that forced alignment should really only be necessary for
use cases like XIP where the file is directly "used" straight from its
location on flash in some way, and those cases can never be compressed
-- however, recent AMD platforms have started using the --align flag to
meet the requirements of their SPI DMA controller and broken this
assumption.
This patch fixes that particular problem and hopefully eliminates a bit
of the convolution by moving the offset decision point in the --align
case after the convert() step. This is safe when the steps in-between
(add_topswap_bootblock() and convert() itself) do not rely on the
location having already been decided by --align before that point. For
the topswap case this is easy, because in practice we always call it
with --base-address (and as far as I can tell that's the only way it was
ever meant to work?) -- so codify that assumption in the function. For
convert() this mostly means that the implementations that do touch the
offset variable (mkstage and FSP) need to ensure they take care of the
alignment themselves. The FSP case is particularly complex so I tried to
rewrite the code in a slightly more straight-forward way and clearly
document the supported cases, which should hopefully make it easier to
see that the offset variable is handled correctly in all of them. For
mkstage the best solution seems to be to only have it touch the offset
variable in the XIP case (where we know compression must be disabled, so
we can rely on it not changing the file size later), and have the extra
space for the stage header directly taken care of by do_cbfs_locate() so
that can happen after convert().
NOTE: This is changing the behavior of `cbfstool add -t fsp` when
neither --base-address nor --xip are passed (e.g. FSP-S). Previously,
cbfstool would implicitly force an alignment of 4K. As far as I can tell
from the comments, this is unnecessary because this binary is loaded
into RAM and CBFS placement does not matter, so I assume this is an
oversight caused by accidentally reusing code that was only meant for
the XIP case.
