The Picasso VBIOS is not setting the reserved_mask_size correctly. This

Kyösti Mälkki 7522a8fe0f arch/x86: Move prologue to .init section
For arch/x86 the realmode part has to be located within the same 64
KiB as the reset vector. Some older intel platforms also require 4 KiB
alignment for _start16bit.

To enforce the above, and to separate required parts of .text without
matching *(.text.*) rules in linker scripts, tag the pre-C environment
assembly code with section .init directive.

Description of .init section for ELF:

This section holds executable instructions that contribute to the
process initialization code. When a program starts to run, the
system arranges to execute the code in this section before calling the
main program entry point (called main for C programs).

Matt DeVillier 8ead1dc875 src/lib: Add Kconfig option for SPD cache in FMAP
Currently, the option to cache DIMM SPD data in an FMAP region
is closely coupled to a single board (google/hatch) and requires
a custom FMAP to utilize.

Loosen this coupling by introducing a Kconfig option which adds
a correctly sized and aligned RW_SPD_CACHE region to the default FMAP.
Add a Kconfig option for the region name, replacing the existing hard-
coded instance in spd_cache.h. Change the inclusion of spd_cache.c to
use this new Kconfig, rather than the board-specific one currently used.
Lastly, have google/hatch select the new Kconfig when appropriate to
ensure no change in current functionality.

Test: build/boot WYVERN google/hatch variant with default FMAP, verify
FMAP contains RW_SPD_CACHE, verify SPD cache used via cbmem log.

Also tested on an out-of-tree Purism board.

Julius Werner 34cf073220 cbfs: Allow mcache to be found after the first lookup
This patch addresses the same problem as CB:48429, but hopefully this
time correctly. Since the mcache is not guaranteed to be available on
the first CBFS lookup for some special cases, we can no longer treat it
as a one-time fire-and-forget initialization. Instead, we test
cbd->mcache_size to check if the mcache has been initialized yet, and
keep trying on every lookup if we don't find it the first time.

Since the mcache is a hard requirement for TOCTOU safety, also make it
more clear in Kconfig that configurations known to do CBFS accesses
before CBMEM init are incompatbile with that, and make sure we die()
rather than do something unsafe if there's a case that Kconfig didn't
catch.

CBFS code fall back to a lookup from flash if CBMEM hasn't been

Julius Werner fdabf3fcd7 cbfs: Add verification for RO CBFS metadata hash
This patch adds the first stage of the new CONFIG_CBFS_VERIFICATION
feature. It's not useful to end-users in this stage so it cannot be
selected in menuconfig (and should not be used other than for
development) yet. With this patch coreboot can verify the metadata hash
of the RO CBFS when it starts booting, but it does not verify individual
files yet. Likewise, verifying RW CBFSes with vboot is not yet
supported.

Verification is bootstrapped from a "metadata hash anchor" structure
that is embedded in the bootblock code and marked by a unique magic
number.  This anchor contains both the CBFS metadata hash and a separate
hash for the FMAP which is required to find the primary CBFS. Both are
verified on first use in the bootblock (and halt the system on failure).

The CONFIG_TOCTOU_SAFETY option is also added for illustrative purposes
to show some paths that need to be different when full protection
against TOCTOU (time-of-check vs. time-of-use) attacks is desired. For
normal verification it is sufficient to check the FMAP and the CBFS
metadata hash only once in the bootblock -- for TOCTOU verification we
do the same, but we need to be extra careful that we do not re-read the
FMAP or any CBFS metadata in later stages. This is mostly achieved by
depending on the CBFS metadata cache and FMAP cache features, but we
allow for one edge case in case the RW CBFS metadata cache overflows
(which may happen during an RW update and could otherwise no longer be
fixed because mcache size is defined by RO code). This code is added to
demonstrate design intent but won't really matter until RW CBFS
verification can be supported.

Julius Werner 834b3ecd7c cbfs: Simplify load/map API names, remove type arguments
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.

Julius Werner 0d9072b1a1 cbfs: Move more stuff into cbfs_boot_lookup()
cbfs_boot_locate() is supposed to be deprecated eventually, after slowly
migrating all APIs to bypass it. That means common features (like
RO-fallback or measurement) need to be moved to the new
cbfs_boot_lookup().

Also export the function externally. Since it is a low-level API and
most code should use the higher-level loading or mapping functions
instead, put it into a new <cbfs_private.h> to raise the mental barrier
for using this API (this will make more sense once cbfs_boot_locate() is
removed from <cbfs.h>).

This patch flips the default of CONFIG_NO_CBFS_MCACHE so the feature is

still have it explicitly disabled. All others get the new section added

Julius Werner 1e37c9ca46 cbfs: Add metadata cache
This patch adds a new CBFS "mcache" (metadata cache) -- a memory buffer
that stores the headers of all CBFS files. Similar to the existing FMAP
cache, this cache should reduce the amount of SPI accesses we need to do
every boot: rather than having to re-read all CBFS headers from SPI
flash every time we're looking for a file, we can just walk the same
list in this in-memory copy and finally use it to directly access the
flash at the right position for the file data.

This patch adds the code to support the cache but doesn't enable it on
any platform. The next one will turn it on by default.

This patch hooks coreboot up to the new commonlib/bsd CBFS
implementation. This is intended as the "minimum viable patch" that
makes the new implementation useable with the smallest amount of changes
-- that is why some of this may look a bit roundabout (returning the
whole metadata for a file but then just using that to fill out the rdevs
of the existing struct cbfsf). Future changes will migrate the higher
level CBFS APIs one-by-one to use the new implementation directly
(rather than translated into the results of the old one), at which point
this will become more efficient.

Patrick Rudolph bc744f5893 drivers/smmstore: Implement SMMSTORE version 2
SMMSTORE version 2 is a complete redesign of the current driver. It is
not backwards-compatible with version 1, and only one version can be
used at a time.

Key features:
* Uses a fixed communication buffer instead of writing to arbitrary
  memory addresses provided by untrusted ring0 code.
* Gives the caller full control over the used data format.
* Splits the store into smaller chunks to allow fault tolerant updates.
* Doesn't provide feedback about the actual read/written bytes, just
  returns error or success in registers.
* Returns an error if the requested operation would overflow the
  communication buffer.

Separate the SMMSTORE into 64 KiB blocks that can individually be
read/written/erased. To be used by payloads that implement a
FaultTolerant Variable store like TianoCore.

The implementation has been tested against EDK2 master.

An example EDK2 implementation can be found here:
