Julius Werner af20fd748b cbfs: Add CBFS_TYPE_INTEL_FIT and exclude it from CBFS verification
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.)

Julius Werner 0057262b38 cbfs: Rename TYPE_FIT to TYPE_FIT_PAYLOAD
There are too many "FIT" in firmware land. In order to reduce possible
confusion of CBFS_TYPE_FIT with the Intel Firmware Interface Table, this
patch renames it to CBFS_TYPE_FIT_PAYLOAD (including the cbfstool
argument, so calling scripts will now need to replace `-t fit` with `-t
fit_payload`).

Arthur Heymans efdcb4634a cbfstool/linux_trampoline: Fill the ACPI RSDP entry
With LinuxBoot Linux relied on the legacy method of fetching the RSDP
pointer to get ACPI. This uses a more modern approach available since
2018 on the Linux kernel, which involves filling in the zero page.

This method takes precedence over any other method of fetching the
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

controversial. We should not be arbitrarily using two different

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.

Julius Werner 772714d3b3 cbfstool: Use converted buffer size for do_cbfs_locate()
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.

Julius Werner 20ad36547e cbfstool: Do host space address conversion earlier when adding files
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.

Julius Werner 6ddacd6f5b cbfstool: Fix offset calculation for aligned files
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.

When using `DECLARE_OPTIONAL_REGION`, it is assumed that
REGION_SIZE(name) == 0 if the region was not defined in the memlayout.
When using non-rmodule stages (i.e., bootblock, romstage, etc), this
assumption holds true, but breaks down in rmodule (i.e., ramstage)
stages.

The rmodule tool is not currently omitting undefined externals from the
relocation table. e.g.,

    extern u8 _##name##_size[];

This means that when the rmodule loader runs, it will rewrite the symbol
from 0 (which is the default the linker assumed) to 0 + offset. This is
wrong since the symbol doesn't actually exist. Instead we need to omit
the relocation so it continues to keep the default value of 0.

in UefiPayloadEntry.fdf in EDKII. There is an ext header between header
of Fv and header of PayloadEntry in Fv with FvNameGuid. The ext header

Ricardo Quesada c2cf3946c9 util/elogtool: add tool to print elog events
Add a new tool that that prints elog events.
The tool, as input, accepts either a file with the RW_ELOG contents, or
if the file is not provided it reads the contents of RW_ELOG by calling
the "flashrom" tool.

The tool is based on "mosys eventlog list"[1]. For the moment it only
supports "list", but future commits will add additional functionality.

This commit also adds missing ELOG defines needed for the tool. These
defines are added with the rest of the ELOG defines, in
include/commonlib/bsd/elog.h

The tool is placed inside util/cbfstool. The rationale behind the
decision, is that this tool shares a lot in common with the other tools
located in cbfstool: vboot dependency, shared files like common.o and
valstr.o, and in spirit is similar to some of the tools located in
cbfstool/.

As an example, you call the tool like the following:

$ elogtool list -f rw_elog_dump.bin

Nico Huber f22f408956 cbfstool: Make use of spurious null-termination
The null-termination of `filetypes` was added after the code was
written, obviously resulting in NULL dereferences. As some more
code has grown around the termination, it's hard to revert the
regression, so let's update the code that still used the array
length.

This fixes commit 7f5f9331d1 (util/cbfstool: fix buffer over-read)
which actually did fix something, but only one path while it broke
two others. We should be careful with fixes, they can always break
something else. Especially when a dumb tool triggered the patching
it seems likely that fewer people looked into related code.

Patrick Rudolph d023909b01 treewide: Disable R_AMD64_32S relocation support
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

Fixes a crash in TSEG and when in long mode seen on Intel Sandybridge.
