2023-08-06cpu: Add SPDX license headers to MakefilesMartin Roth
To help identify the licenses of the various files contained in the coreboot source, we've added SPDX headers to the top of all of the .c and .h files. This extends that practice to Makefiles. Any file in the coreboot project without a specific license is bound to the license of the overall coreboot project, GPL Version 2. This patch adds the GPL V2 license identifier to the top of all makefiles in the cpu directory that don't already have an SPDX license line at the top.

2023-07-08cpu: Enable per-CPUID microcode loading in CBFSSubrata Banik
The current design of the `ucode-<variant>.bin` file combines all possible microcode per cpuid into a unified blob. This model increases the microcode loading time from RW CBFS due to higher CBFS verification time (the bigger the CBFS binary the longer the verification takes). This patch creates a provision to pack individual microcodes (per CPUID) into the CBFS (RO and RWs). Implementation logic introduces CPU_INTEL_MICROCODE_CBFS_SPLIT_BINS config which relies on converting Intel CPU microcode INC file into the binary file as per format specified as in `cpu_microcode_$(CPUID).bin`. For example: Intel CPU microcode `m506e3.inc` to convert into `cpu_microcode_506e3.bin` binary file for coreboot to integrate if CPU_INTEL_MICROCODE_CBFS_SPLIT_BINS config is enabled. Another config named CPU_INTEL_UCODE_SPLIT_BINARIES is used to specify the directory name (including path) that holds the split microcode binary files per CPUID for each coreboot variants. For example: if google/kunimitsu had built with Intel SkyLake processor with CPUID `506e3` and `506e4` then CPU_INTEL_UCODE_SPLIT_BINARIES refers to the directory path that holds the split microcode binary files aka cpu_microcode_506e3.bin and cpu_microcode_506e4.bin. Refer to the file representation below: |---3rdparty | |--- blobs | | |--- mainboard | | | |--- google | | | | |--- kunimitsu | | | | | |--- microcode_inputs | | | | | | |--- kunimitsu | | | | | | | |--- cpu_microcode_506e3.bin | | | | | | | |--- cpu_microcode_506e4.bin Users of this config option requires to manually place the microcode binary files per CPUIDs as per the given format (`cpu_microcode_$(CPUID).bin`) in a directory. Finally specify the microcode binary directory path using CPU_UCODE_SPLIT_BINARIES config. Additionally, modified the `find_cbfs_microcode()` logic to search microcode from CBFS by CPUID. This change will improve the microcode verification time from the CBFS, and will make it easier to update individual microcodes.

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.)

2022-04-01cpu/intel/fit: Clear the FIT table when setting pointerArthur Heymans
When rebuilding coreboot the empty fit table added to added to CBFS stays the same so the build process sees no reason to update the file. In the meantime ifittool did update that file for instance to add microcode update entries. So each time coreboot is rebuilt the entries are appended to the FIT table which runs out of space at some point. One way to deal with this is to clear the fit table when setting the pointer inside the bootblock. TESTED: Now running 'make' again on prodrive/hermes does not report an error with a filled FIT table.

2021-03-19cpu/intel/fit: Add the FIT table as a separate CBFS fileArthur Heymans
With CBnT a digest needs to be made of the IBB, Initial BootBlock, in this case the bootblock. After that a pointer to the BPM, Boot Policy Manifest, containing the IBB digest needs to be added to the FIT table. If the fit table is inside the IBB, updating it with a pointer to the BPM, would make the digest invalid. The proper solution is to move the FIT table out of the bootblock. The FIT table itself does not need to be covered by the digest as it just contains pointers to structures that can by verified by the hardware itself, such as microcode and ACMs (Authenticated Code Modules).

2015-10-07x86/bootblock: Use LDFLAGS_bootblock to enable garbage collectionAlexandru Gagniuc
The x86 bootblock linking is a mess. The bootblock is treated in a very special manner, and never received the update to link-time garbage collection. On newer x86 platforms, the boot media is no longer memory-mapped. That means we need to do a lot more setup in the bootblock. ROMCC is unsuitable for this task, and walkcbfs only works on memory-mapped CBFS. We need to revise the x86 bootflow for this new case. The approach this patch series takes is to perform CAR setup in the bootblock, and load the following stage (either romstage or verstage) from the boot media. This approach is not new, but has been done on our ARM ports for years. Since we will be adding .c files to the bootblock, it is prudent to use link-time garbage collection. This is also consistent to how we do things on other architectures. Unification FTW!
