Kyösti Mälkki 4f51b0f7fe arch/x86: Fix payload loading via bounce-buffer
Fix regression (supposedly) after commit:

  23d62dd lib/bootmem: Add more bootmem tags

Without RELOCATABLE_RAMSTAGE, payload is allowed to overwrite
memory regions of the running ramstage. This case is handled
gracefully via a bounce-buffer implementation in arch/x86/boot.c.

Julius Werner 99f4683adf Introduce bootblock self-decompression
Masked ROMs are the silent killers of boot speed on devices without
memory-mapped SPI flash. They often contain awfully slow SPI drivers
(presumably bit-banged) that take hundreds of milliseconds to load our
bootblock, and every extra kilobyte of bootblock size has a hugely
disproportionate impact on boot speed. The coreboot timestamps can never
show that component, but it impacts our users all the same.

This patch tries to alleviate that issue a bit by allowing us to
compress the bootblock with LZ4, which can cut its size down to nearly
half. Of course, masked ROMs usually don't come with decompression
algorithms built in, so we need to introduce a little decompression stub
that can decompress the rest of the bootblock. This is done by creating
a new "decompressor" stage which runs before the bootblock, but includes
the compressed bootblock code in its data section. It needs to be as
small as possible to get a real benefit from this approach, which means
no device drivers, no console output, no exception handling, etc.
Besides the decompression algorithm itself we only include the timer
driver so that we can measure the boot speed impact of decompression. On
ARM and ARM64 systems, we also need to give SoC code a chance to
initialize the MMU, since running decompression without MMU is
prohibitively slow on these architectures.

This feature is implemented for ARM and ARM64 architectures for now,
although most of it is architecture-independent and it should be
relatively simple to port to other platforms where a masked ROM loads
the bootblock into SRAM. It is also supposed to be a clean starting
point from which later optimizations can hopefully cut down the
decompression stub size (currently ~4K on RK3399) a bit more.

NOTE: Bootblock compression is not for everyone. Possible side effects
include trying to run LZ4 on CPUs that come out of reset extremely
underclocked or enabling this too early in SoC bring-up and getting
frustrated trying to find issues in an undebuggable environment. Ask
your SoC vendor if bootblock compression is right for you.

Nico Huber 4a027e6e95 lib/gnat: Drop Restriction `No_Exception_Propagation`
It turns out that even with the `-gnatp` switch to suppress runtime
checks, the compiler is still allowed to generate them (it only doesn't
have to). If we can't control generation of checks, we also can't
make assumptions about propagation of their exceptions.

The compiler warning that led to this change seems spurious, though
(the check might be generated, but is dropped later). So we might
revert this decision if the compiler can be fixed.

Julius Werner ae05d095b3 bootmem: Keep OS memory map separate from the start
The patch series ending in 64049be (lib/bootmem: Add method to walk OS
POV memory tables) expanded the bootmem framework to also keep track of
memory regions that are only relevant while coreboot is still executing,
such as the ramstage code and data. Mixing this into the exsting bootmem
ranges has already caused an issue on CONFIG_RELOCATEABLE_RAMSTAGE
boards, because the ramstage code in CBMEM is marked as BM_RAMSTAGE
which ends up getting translated back to LB_RAM in the OS tables. This
was fixed in 1ecec5f (lib/bootmem: ensure ramstage memory isn't given to
OS) for this specific case, but unfortunately Arm boards can have a
similar problem where their stack space is sometimes located in an SRAM
region that should not be made available as RAM to the OS.

Since both the resources made available to the OS and the regions
reserved for coreboot can be different for each platform, we should find
a generic solution to this rather than trying to deal with each issue
individually. This patch solves the problem by keeping the OS point of
view and the coreboot-specific ranges separate from the start, rather
than cloning it out later. Ranges only relevant to the coreboot view
will never touch the OS-specific layout, to avoid the problem of losing
information about the original memory type of the underlying region that
needs to be restored for the OS view. This both supersedes the
RELOCATABLE_RAMSTAGE fix and resolves the problems on Arm boards.

Introduce new bootmem tags to allow more fine grained control over buffer
allocation on various platforms. The new tags are:

BM_MEM_RAMSTAGE : Memory where any kind of boot firmware resides and that
                  should not be touched by bootmem (by example: stack,
                  TTB, program, ...).
BM_MEM_PAYLOAD  : Memory where any kind of payload resides and that should
                  not be touched by bootmem.

Starting with this commit all bootmem methods will no longer see memory
that is used by coreboot as usable RAM.

Bootmem changes:
* Introduce a weak function to add platform specific memranges.
* Mark memory allocated by bootmem as BM_TAG_PAYLOAD.
* Assert on failures.
* Add _stack and _program as BM_MEM_RAMSTAGE.

ARMv7 and ARMv8 specific changes:
* Add _ttb and _postram_cbfs_cache as BM_MEM_RAMSTAGE.

ARMv7 specific changes:
* Add _ttb_subtables as BM_MEM_RAMSTAGE.

Julius Werner 96ed92d49d boardid: Add helpers to read sku_id strapping into coreboot tables
On many recent Chrome OS boards, the desire to unite more configurations
under the same image has led to the need of a "SKU ID" that identifies
different configurations of the same board (e.g. with certain optional
components stuffed or not stuffed, or replaced with a comparable
component). This is markedly different from the existing "board ID",
because that is reserved to count "revisions" -- changes made to the
same configuration over time during the development process. This patch
adds support to have a mainboard define this SKU ID and pass it through
the coreboot table like we already have for board IDs.

This patch switches the board_id and ram_code helper framework to use
weak functions rather than Kconfigs to determine whether the board
supplies these IDs. This cuts down on the amount of boilerplate Kconfigs
many boards have to set and also gives them more flexibility, such as
being able to determine at runtime whether a given ID is present.

mainboard implementation needs its own print. (In turn, remove one such
print from fsp1_1 code because it's in the way of my next patch.)

further refactoring of other options easier.

Also shove some stuff back into the Urara mainboard that should've never

Vadim Bendebury 08f93599a9 cr50: process uninitialized values gracefully
The vboot code tries reading rollback protection indices from the TPM,
and if the attempt to read returns TPM_E_BADINDEX, it decides that the
TPM has not yet been initialized for the Chromebook use, and needs to
be taken through the factory initialization sequence.

TPM_E_BADINDEX is an internal representation of the TPM error 0x28b,
generated on attempts to read a non existing NVMEM space.

If the space exists, but has never been written the TPM returns error
0x14a. This condition (the space exists but not written) could happen
if the previous factory initialization attempt was interrupted right
after the space was created.

Let's map this error to the same internal representation
(TPM_E_BADINDEX) so that the Chrome OS device could recover when this
condition occurs.

BRANCH=reef, gru

Julius Werner 01f9aa5e54 Consolidate reset API, add generic reset_prepare mechanism
There are many good reasons why we may want to run some sort of generic
callback before we're executing a reset. Unfortunateley, that is really
hard right now: code that wants to reset simply calls the hard_reset()
function (or one of its ill-differentiated cousins) which is directly
implemented by a myriad of different mainboards, northbridges, SoCs,
etc. More recent x86 SoCs have tried to solve the problem in their own
little corner of soc/intel/common, but it's really something that would
benefit all of coreboot.

This patch expands the concept onto all boards: hard_reset() and friends
get implemented in a generic location where they can run hooks before
calling the platform-specific implementation that is now called
do_hard_reset(). The existing Intel reset_prepare() gets generalized as
soc_reset_prepare() (and other hooks for arch, mainboard, etc. can now
easily be added later if necessary). We will also use this central point
to ensure all platforms flush their cache before reset, which is
generally useful for all cases where we're trying to persist information
in RAM across reboots (like the new persistent CBMEM console does).

Also remove cpu_reset() completely since it's not used anywhere and
doesn't seem very useful compared to the others.

Julius Werner d906bb68c3 cbmem_console: Improve 'cbmem -1' behavior for truncated pre-CBMEM logs
The 'cbmem -1' flag that cuts off console output before the last boot
will ignore content from earlier stages if it was truncated due to lack
of pre-CBMEM console space. This patch makes the "log truncated" message
more specific and adds it as an additional cut-off marker to 'cbmem -1'
to counteract that problem.

Also raise the log level of the coreboot banner one step to BIOS_NOTICE
to make it more likely to be included in the output for 'cbmem -1' to
find. (I believe NOTICE is reasonable but I wouldn't want to go as far
as WARN which should be reserved for actual problems. Of course this is
not ideal, but then again, our whole log-level system really isn't... it
would be better if we could make it always print a banner to the CBMEM
console without affecting the UART at the same time, but that would
require a larger amount of work.)

Julius Werner d67c6876b5 Turn CBMEM console into a ring buffer that can persist across reboots
This patch allows the CBMEM console to persist across reboots, which
should greatly help post factum debugging of issues involving multiple
reboots. In order to prevent the console from filling up, it will
instead operate as a ring buffer that continues to evict the oldest
lines once full. (This means that if even a single boot doesn't fit into
the buffer, we will now drop the oldest lines whereas previous code
would've dropped the newest lines instead.)

The console control structure is modified in a sorta
backwards-compatible way, so that new readers can continue to work with
old console buffers and vice versa. When an old reader reads a new
buffer that has already once overflowed (i.e. is operating in true ring
buffer mode) it will print lines out of order, but it will at least
still print out the whole console content and not do any illegal memory
accesses (assuming it correctly implemented cursor overflow as it was
already possible before this patch).

Youness Alaoui d24dbf9902 src/lib/jpeg: Fix missing closing brace
There's a missing closing brace in fillbits function of jpeg.c which
caused an avalanche of compilation errors.

This was introduced in commit
491c5b60 (src/lib: Move assignment out of if condition)
which was reviewed in gerrit at https://review.coreboot.org/18761 and it
prevents coreboot from building when CONFIG_BOOTSPLASH is set.

Julius Werner e91d170d21 Remove libverstage as separate library and source file class
In builds without CONFIG_VBOOT_SEPARATE_VERSTAGE, verstage files are
linked directly into the bootblock or the romstage. However, they're
still compiled with a separate "libverstage" source file class, linked
into an intermediate library and then linked into the final destination
stage.

There is no obvious benefit to doing it this way and it's unclear why it
was chosen in the first place... there are, however, obvious
disadvantages: it can result in code that is used by both libverstage
and the host stage to occur twice in the output binary. It also means
that libverstage files have their separate compiler flags that are not
necessarily aligned with the host stage, which can lead to weird effects
like <rules.h> macros not being set the way you would expect. In fact,
VBOOT_STARTS_IN_ROMSTAGE configurations are currently broken on x86
because their libverstage code that gets compiled into the romstage sets
ENV_VERSTAGE, but CAR migration code expects all ENV_VERSTAGE code to
run pre-migration.

This patch resolves these problems by removing the separate library.
There is no more difference between the 'verstage' and 'libverstage'
classes, and the source files added to them are just treated the same
way a bootblock or romstage source files in configurations where the
verstage is linked into either of these respective stages (allowing for
the normal object code deduplication and causing those files to be
compiled with the same flags as the host stage's files).

Tested this whole series by booting a Kevin, an Elm (both with and
without SEPARATE_VERSTAGE) and a Falco in normal and recovery mode.

Julius Werner 58c3938705 vboot: Move remaining features out of vendorcode/google/chromeos
This patch attempts to finish the separation between CONFIG_VBOOT and
CONFIG_CHROMEOS by moving the remaining options and code (including
image generation code for things like FWID and GBB flags, which are
intrinsic to vboot itself) from src/vendorcode/google/chromeos to
src/vboot. Also taking this opportunity to namespace all VBOOT Kconfig
options, and clean up menuconfig visibility for them (i.e. some options
were visible even though they were tied to the hardware while others
were invisible even though it might make sense to change them).

Julius Werner 84b2978ed6 chromeos: Remove old MOCK_TPM references
The correct way to mock out vboot TPM accesses these days is the
CONFIG_VBOOT_MOCK_SECDATA Kconfig option. There are some remnants of
older TPM-mocking infrastructure in our codebase that are as far as I
can tell inert. Remove them.

Vadim Bendebury 021ec2819b cr50: add unmarshaling of vendor commands and process 'enable_update'
The upcoming Cr50 firmware changes will require the AP to enable the
previously downloaded Cr50 firmware update(s).

A new vendor command (TPM2_CR50_SUB_CMD_TURN_UPDATE_ON) is used for
that. The command accepts one parameter - a timeout value in range of
0 to 1000 ms.

When processing the command the Cr50 checks if the alternative RO or
RW image(s) need to be enabled, and if so - enables them and returns
to the host the number of enabled headers.

If the vendor command requested a non-zero timeout, the Cr50 starts
a timer to trigger system reboot after the requested timeout expires.

The host acts on the number of enabled headers - if the number is
nonzero, the host prepares the device to be reset and waits for the
Cr50 to reboot the device after timeout expires.

This patch also adds more formal vendor command
marshaling/unmarshaling to make future additions easier.

BRANCH=gru,reef
BUG=b:35580805
TEST=with the actual user of this code in the next patch verified that
     the cr50 update is enabled as expected.
