The hook + can be provided by, for example, mainboard code. + +Background: We are currently working on mainboard code for qemu-sbsa and +Neoverse N2. Both require a valid PPTT table. Patch was tested against +the qemu-sbsa board. + + +### acpi: Add support for WDAT table + +This commit lays the groundwork for implementing the ACPI WDAT (Watchdog +Action Table) table specification. The WDAT is a special ACPI table +introduced by Microsoft that describes the watchdog for the OS. + +Platforms that need to implement the WDAT table must describe the +hardware watchdog management operations as described in the +specification.

Wrangling includes parsing, decoding and encoding. + +It compiles its library, written in its own language, to a C/C++ source +file that can then be used independently without needing support for the +language. That library is now imported to src/vendorcode/wuffs/. + +This change modifies our linters to ignore that directory because it's +supposed to contain the wuffs compiler's result verbatim. + +Nigel Tao provided an initial wrapper around wuffs' jpeg decoder that +implements our JPEG API. I further changed it a bit regarding data +placement, dropped stuff from our API that wasn't ever used, or isn't +used anymore, and generally made it fit coreboot a bit better. Features +are Nigel's, bugs are mine. + +This commit also adapts our jpeg fuzz test to work with the modified +API. After limiting it to deal only with approximately screen sized +inputs, it fuzzed for 25 hours CPU time without a single hang or crash. +This is a notable improvement over running the test with our old decoder +which crashes within a minute. + +Finally, I tried the new parser with a pretty-much-random JPEG file I +got from the internet, and it just showed it (once the resolution +matched), which is also a notable improvement over the old decoder which +is very particular about the subset of JPEG it supports. + +In terms of code size, a QEmu build's ramstage increases +from 128060 bytes decompressed (64121 bytes after LZMA) + to 172304 bytes decompressed (82734 bytes after LZMA). + +[0] https://github.com/google/wuffs Additional coreboot changes --------------------------- -The following are changes across a number of patches, or changes worth -noting, but not needing a full description. +* Rename Makefiles from .inc to .mk to better identify them +* SPI: Add GD25LQ255E and IS25WP256D chip support +* device: Add support for multiple PCI segment groups +* device: Drop unused multiple downstream link support +* device: Rename bus and link_list to upstream and downstream +* Updated devicetree files for modern Intel platforms to use chipset.cb +* Updated xeon-sp to use the coreboot allocator -* Changes that only need a line or two of description go here.
