2022-09-02cbfs/vboot: Adapt to new vb2_digest APIJulius Werner
CL:3825558 changes all vb2_digest and vb2_hash functions to take a new hwcrypto_allowed argument, to potentially let them try to call the vb2ex_hwcrypto API for hash calculation. This change will open hardware crypto acceleration up to all hash calculations in coreboot (most notably CBFS verification). As part of this change, the vb2_digest_buffer() function has been removed, so replace existing instances in coreboot with the newer vb2_hash_calculate() API. Due to the circular dependency of these changes with vboot, this patch also needs to update the vboot submodule: Updating from commit id 18cb85b5: 2load_kernel.c: Expose load kernel as vb2_api to commit id b827ddb9: tests: Ensure auxfw sync runs after EC sync This brings in 15 new commits.

2022-09-01x86/cache.c: Implement dcache_*Hsin-Te Yuan
A new ChromeOS automated test will be introduced to check the cbmem log of diagnostic boot mode. Because the diagnostic boot does not allow booting into kernel, the test must perform AP reset and then check the cbmem log afterwards. However, the memory content might not be written back to memory (from CPU cache) during AP reset because of the cache snooping mechanism on x86. Hence, some API to flush cache is needed. Implement dcache_* to allow flushing cache proactively in x86. To avoid unnecessary flush, check dma_coherent before calling dcache_* functions, which will be always true in x86. Therefore, this change won't affect the original functionality.

2022-01-14libpayload: Fix legacy CBFS code after recent refactoringJulius Werner
The goal when adding the new CBFS API in CB:59497 was that the old CBFS code would be left completely untouched and just moved to the side a bit, so that it could continue to work for the payloads that use it until they all have time to transition to the new CBFS API. Unfortunately, between the different iterations of the patch something went wrong with that and the final committed version of cbfs_legacy.c does differ in some parts from the original code, including a changed macro definition that breaks decompression support.

2020-12-08coreboot tables: Add SPI flash memory map windows to coreboot tablesFurquan Shaikh
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.

2020-10-22drivers/smmstore: Implement SMMSTORE version 2Patrick Rudolph
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: https://github.com/9elements/edk2-1/commit/eb1127744a3a5d5c8ac4e8eb76f07e79c736dbe2 Change-Id: I25e49d184135710f3e6dd1ad3bed95de950fe057 Signed-off-by: Patrick Rudolph <patrick.rudolph@9elements.com> Signed-off-by: Christian Walter <christian.walter@9elements.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/40520 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Michał Żygowski <michal.zygowski@3mdeb.com> Reviewed-by: Matt DeVillier <matt.devillier@gmail.com>

The latter would be unaffected by a relocation of the payload. Instead of the pointer, we'll always keep a copy of the whole struct, which can be altered on demand without affecting the coreboot table.

Add a function draw_line() to draw either a horizontal or vertical line segment. Theoretically a horizontal line can also be drawn by calling draw_rounded_box() with dim_rel.x being the line length and dim_rel.y being the line width. However, due to the truncation in integer division when converting relative coordinates to absolute ones, this will potentially produce inconsistent line widths, depending on the value of pos_rel.y. It is guaranteed that draw_line() will produce consistent line widths, regardless of the position of the line. Also, when the thickness argument is zero, this function is able to draw a line with 1-pixel width, which is not achievable by draw_rounded_box().

struct fraction is slooooooooooow. This patch adds a simple 64-bit (32-bits integral, 32-bits fractional) fixed-point math API that is *much* faster (observed roughly 5x speed-up) when doing intensive graphics operations. It is optimized for speed over accuracy so some operations may lose a bit more precision than expected, but overall it's still plenty of bits for most use cases. Also includes support for basic trigonometric functions with a small lookup table.

2019-08-22Add buffer_to/from_fifo32(_prefix) helpersJulius Werner
Many peripheral drivers across different SoCs regularly face the same task of piping a transfer buffer into (or reading it out of) a 32-bit FIFO register. Sometimes it's just one register, sometimes a whole array of registers. Sometimes you actually transfer 4 bytes per register read/write, sometimes only 2 (or even 1). Sometimes writes need to be prefixed with one or two command bytes which makes the actual payload buffer "misaligned" in relation to the FIFO and requires a bunch of tricky bit packing logic to get right. Most of the times transfer lengths are not guaranteed to be divisible by 4, which also requires a bunch of logic to treat the potential unaligned end of the transfer correctly. We have a dozen different implementations of this same pattern across coreboot. This patch introduces a new family of helper functions that aims to solve all these use cases once and for all (*fingers crossed*).
