2023-08-03linux_trampoline: Handle 64-bit framebuffer addressesNico Huber
To support full 64-bit addresses, there is a new field `ext_lfb_base` since Linux 4.1. It is unclear, however, how a loader is supposed to know if the kernel is compatible with this. Filling these previously reserved bits doesn't hurt, but an old kernel would probably ignore them and not know that it's handling a clipped, invalid address. So we play safe, and only allow 64-bit addresses for kernels after the 2.15 version bump of the boot protocol.

2023-06-23soc/intel/alderlake/hsphy: Add possibility to cache HSPHY in flashMichał Żygowski
The patch adds a possibility to cache the PCIe 5.0 HSPHY firmware in the SPI flash. New flashmap region is created for that purpose. The goal of caching is to reduce the dependency on CSME and the HECI IP LOAD command which may fail when the CSME is disabled, e.g. soft disabled by HECI command or HAP disabled. This change allows to keep PCIe 5.0 root ports functioning even if CSME/HECI is not functional. TEST=Boot Ubuntu 22.04 on MSI PRO Z690-A and notice PCIe 5.0 port is functional after loading the HSPHY from cache.

This reverts commit 89b4f69746ac215e4a7c5f204d1ea807b4ea08b5. SI_BIOS is mostly used to indicate the BIOS region in Intel IFD. Not all platforms are Intel platforms with an IFD, so revert this change. Also tooling often depends on names not changing so renaming things should not be done lightly. The default region should also be in sync with non-x86 and made systematic across the tree.

This replaces the mechanism with --ext-win-base --ext-win-size with a more generic mechanism where cbfstool can be provided with an arbitrary memory map. This will be useful for AMD platforms with flash sizes larger than 16M where only the lower 16M half gets memory mapped below 4G. Also on Intel system the IFD allows for a memory map where the "top of flash" != "below 4G". This is for instance the case by default on Intel APL. TEST: google/brya build for chromeos which used --ext-win-base remains the same after this change with BUILD_TIMELESS=1.

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.

2022-07-14commonlib: Substitude macro "__unused" in compiler.hBill XIE
Since there are many identifiers whose name contain "__unused" in headers of musl libc, introducing a macro which expands "__unused" to the source of a util may have disastrous effect during its compiling under a musl-based platform. However, it is hard to detect musl at build time as musl is notorious for having explicitly been refusing to add a macro like "__MUSL__" to announce its own presence. Using __always_unused and __maybe_unused for everything may be a good idea. This is how it works in the Linux kernel, so that would at least make us match some other standard rather than doing our own thing (especially since the other compiler.h shorthand macros are also inspired by Linux).

2022-06-16util/cbfstool: Decouple elogtool from vboot_ref flashrom codeEdward O'Callaghan
Currently elogtool sub-proccesses flashrom as calling libflashrom requires a missing function from the previous flashrom release. Pending a new release of flashrom we must continue to use subprocess. However the current subprocess wrapper implementation lives in vboot_reference which is a git sub-module of coreboot. This causes all sorts of grief keeping a subprocess ABI stable from vboot_reference when the rest of vboot_reference builds of HEAD of the flashrom tree (i.e., using unreleased libflashrom functions). In order to not keep finding ourseleves in a bind between the two separately moving trees with different build environments, decouple elogtool with its own mini copy of flashrom subprocess wrapping logic.

2022-06-01cbfs: Add CBFS_TYPE_INTEL_FIT and exclude it from CBFS verificationJulius Werner
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.)

2021-12-13cbfstool: Do host space address conversion earlier when adding filesJulius Werner
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.

2021-12-07cbfstool: Fix offset calculation for aligned filesJulius Werner
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 building cbfstool standalone, these executables are placed in `util/cbfstool/`, and Git should never track them.

2021-10-20util/cbfstool/rmodule: Omit undefined extern symbols from reloc tableRaul E Rangel
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. BUG=b:179699789 TEST=Print out REGION_SIZE(cbfs_cache) in ramstage and verify it is set to 0.

2021-06-15treewide: Disable R_AMD64_32S relocation supportPatrick Rudolph
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.

2021-03-17cbfs: Move stage header into a CBFS attributeJulius Werner
The CBFS stage header is part of the file data (not the header) from CBFS's point of view, which is problematic for verification: in pre-RAM environments, there's usually not enough scratch space in CBFS_CACHE to load the full stage into memory, so it must be directly loaded into its final destination. However, that destination is decided from reading the stage header. There's no way we can verify the stage header without loading the whole file and we can't load the file without trusting the information in the stage header. To solve this problem, this patch changes the CBFS stage format to move the stage header out of the file contents and into a separate CBFS attribute. Attributes are part of the metadata, so they have already been verified before the file is loaded. Since CBFS stages are generally only meant to be used by coreboot itself and the coreboot build system builds cbfstool and all stages together in one go, maintaining backwards-compatibility should not be necessary. An older version of coreboot will build the old version of cbfstool and a newer version of coreboot will build the new version of cbfstool before using it to add stages to the final image, thus cbfstool and coreboot's stage loader should stay in sync. This only causes problems when someone stashes away a copy of cbfstool somewhere and later uses it to try to extract stages from a coreboot image built from a different revision... a debugging use-case that is hopefully rare enough that affected users can manually deal with finding a matching version of cbfstool. The SELF (payload) format, on the other hand, is designed to be used for binaries outside of coreboot that may use independent build systems and are more likely to be added with a potentially stale copy of cbfstool, so it would be more problematic to make a similar change for SELFs. It is not necessary for verification either, since they're usually only used in post-RAM environments and selfload() already maps SELFs to CBFS_CACHE before loading them to their final destination anyway (so they can be hashed at that time).

2021-03-16cbfstool: Move alignment/baseaddress handling into cbfs_add_component()Julius Werner
The --alignment flag is currently only handled by cbfstool add, but there seems little reason to not handle it for all file-adding commands (the help text actually mentions it for add-stage as well but it doesn't currently work there). This patch moves the related code (and the related baseaddress handling) into cbfs_add_component(). As a nice side effect this allows us to rearrange cbfs_add_component() such that we can conclusively determine whether we need a hash attribute before trying to align the file, allowing that code to correctly infer the final header size even when a hash attribute was implicitly added (for an image built with CBFS verification enabled).

2021-03-13cbfstool: Add support for platform "fixups" when modifying bootblockJulius Werner
To support the new CONFIG_CBFS_VERIFICATION feature, cbfstool needs to update the metadata hash embedded in the bootblock code every time it adds or removes a CBFS file. This can lead to problems on certain platforms where the bootblock needs to be specially wrapped in some platform-specific data structure so that the platform's masked ROM can recognize it. If that data structure contains any form of hash or signature of the bootblock code that is checked on every boot, it will no longer match if cbfstool modifies it after the fact. In general, we should always try to disable these kinds of features where possible (they're not super useful anyway). But for platforms where the hardware simply doesn't allow that, this patch introduces the concept of "platform fixups" to cbfstool. Whenever cbfstool finds a metadata hash anchor in a CBFS image, it will run all built-in "fixup probe" functions on that bootblock to check if it can recognize it as the wrapper format for a platform known to have such an issue. If so, it will register a corresponding fixup function that will run whenever it tries to write back modified data to that bootblock. The function can then modify any platform-specific headers as necessary. As first supported platform, this patch adds a fixup for Qualcomm platforms (specifically the header format used by sc7180), which recalculates the bootblock body hash originally added by util/qualcomm/createxbl.py. (Note that this feature is not intended to support platform-specific signature schemes like BootGuard directly in cbfstool. For anything that requires an actual secret key, it should be okay if the user needs to run a platform-specific signing tool on the final CBFS image before flashing. This feature is intended for the normal unsigned case (which on some platforms may be implemented as signing with a well-known key) so that on a board that is not "locked down" in any way the normal use case of manipulating an image with cbfstool and then directly flashing the output file stays working with CONFIG_CBFS_VERIFICATION.)

2021-03-13cbfstool: Support CONFIG_CBFS_VERIFICATION and metadata hash anchorJulius Werner
This patch adds support for the new CONFIG_CBFS_VERIFICATION feature to cbfstool. When CBFS verification is enabled, cbfstool must automatically add a hash attribute to every CBFS file it adds (with a handful of exceptions like bootblock and "header" pseudofiles that are never read by coreboot code itself). It must also automatically update the metadata hash that is embedded in the bootblock code. It will automatically find the metadata hash by scanning the bootblock for its magic number and use its presence to auto-detect whether CBFS verification is enabled for an image (and which hash algorithm to use).

2021-02-18cbfstool: Replace FILENAME_ALIGN 16 with ATTRIBUTE_ALIGN 4Julius Werner
cbfstool has always had a CBFS_FILENAME_ALIGN that forces the filename field to be aligned upwards to the next 16-byte boundary. This was presumably done to align the file contents (which used to come immediately after the filename field). However, this hasn't really worked right ever since we introduced CBFS attributes. Attributes come between the filename and the contents, so what this code currently does is fill up the filename field with extra NUL-bytes to the boundary, and then just put the attributes behind it with whatever size they may be. The file contents don't end up with any alignment guarantee and the filename field is just wasting space. This patch removes the old FILENAME_ALIGN, and instead adds a new alignment of 4 for the attributes. 4 seems like a reasonable alignment to enforce since all existing attributes (with the exception of weird edge cases with the padding attribute) already use sizes divisible by 4 anyway, and the common attribute header fields have a natural alignment of 4. This means file contents will also have a minimum alignment guarantee of 4 -- files requiring a larger guarantee can still be added with the --alignment flag as usual.
