2022-02-05cpu/x86/lapic: Move LAPIC configuration to MP initKyösti Mälkki
Implementation for setup_lapic() did two things -- call enable_lapic() and virtual_wire_mode_init(). In PARALLEL_MP case enable_lapic() was redundant as it was already executed prior to initialize_cpu() call. For the !PARALLEL_MP case enable_lapic() is added to AP CPUs.

2022-01-23lib/cbmem_console: Add cbmemc_copy_in functionRaul E Rangel
When running in verstage before bootblock, the PSP (ARM co-processor) is running with limited SRAM. It needs to stash the verstage console data internally until DRAM is brought up. Once DRAM is brought up the data is stashed in a "transfer buffer" region. In the current design, we are using the same region for the transfer buffer and the preram_cbmem_console region. This has the following downsides: 1) The pre-x86 buffer needs to be large enough to hold all the verstage, bootblock and romstage console logs. 2) On AMD platforms, the PSP verstage is signed. Changing the size of preram_cbmem_console after the fact will result in a mismatch of the transfer buffer between verstage and bootblock. This CL adds a new method that allows SoC specific code to copy the CBMEM console in the transfer buffer to the active CBMEM console.

2021-11-30cbfs: Add unverified_area APIsJulius Werner
This patch adds a new ..._unverified_area_... group of functions to the cbfs_map/_load/_alloc() APIs. These functions can be used to access custom FMAP sections and are meant to replace the existing cbfs_locate_file_in_region(). The name is intended to highlight that accesses through this API will not be verified when CBFS_VERIFICATION is enabled and should always be treated as if they may return malicious data. (Due to laziness I'm not adding the combination of this API with the ..._type_... variant at this point, since it seems very unlikely that we'll ever have a use case for that. If we ever do, it should be easy to add later.) (Also remove the 'inline' from cbfs_file_hash_mismatch(). I'm not sure why I put it there in the first place, probably a bad copy&paste.)

2021-11-17cbfs: Add helper functions to look up size and type of a fileJulius Werner
This patch adds cbfs_get_size() and cbfs_get_type() helper functions (and _ro_ variations) to look up the size or type of a CBFS file without loading it. Generally, use of these should be discouraged because that tends to mean that the file needs to be looked up more than once, and cbfs_alloc() or cbfs_type_load() are usually the more efficient alternative... but sometimes they're unavoidable, so we might as well offer them. Also remove the <cbfs_private.h> header which had already become sort of unnecessary with previous changes. cbfs_boot_lookup() is now exported in <cbfs.h> for use in inlines, but should not be used directly by other files (and is prefixed with an underscore to highlight that).

2021-11-16lib/prog_loaders, soc/amd/: Make payload_preload use cbfs_preloadRaul E Rangel
Now that CBFS has this functionality built in, we no longer need to manually code it. payload_preload used to use the payload_preload_cache region to store the raw payload contents. This region was placed outside the firmware reserved region, so it was available for use by the OS. This was possible because the payload isn't loaded again on S3 resume. cbfs_preload only uses the cbfs_cache region. This region must be reserved because it gets used on the S3 resume path. Unfortunately this means that cbfs_cache must be increased to hold the payload. Cezanne is the only platform currently using payload_preload, and the size of cbfs_cache has already been adjusted. In the future we could look into adding an option to cbfs_preload that would allow it to use a different memory pool for the cache allocation.

This API will hide all the complexity of preloading a CBFS file. It makes it so the callers simply specify the file to preload and CBFS takes care of the rest. It will start a new thread to read the file into the cbfs_cache. When the file is actually required (i.e., cbfs_load, etc) it will wait for the preload thread to complete (if it hasn't already) and perform verification/decompression using the preloaded buffer.

2021-11-04SMBIOS/SCONFIG: Allow devtree-defined Type 41 entriesAngel Pons
Introduce the `smbios_dev_info` devicetree keyword to specify the instance ID and RefDes (Reference Designation) of onboard devices. Example syntax: device pci 1c.0 on # PCIe Port #1 device pci 00.0 on smbios_dev_info 6 end end device pci 1c.1 on # PCIe Port #2 device pci 00.0 on smbios_dev_info 42 "PCIe-PCI Time Machine" end end The `SMBIOS_TYPE41_PROVIDED_BY_DEVTREE` Kconfig option enables using this syntax to control the generated Type 41 entries. When this option is enabled, Type 41 entries are only autogenerated for devices with a defined instance ID. This avoids having to keep track of which instance IDs have been used for every device class. Using `smbios_dev_info` when `SMBIOS_TYPE41_PROVIDED_BY_DEVTREE` is not enabled will result in a build-time error, as the syntax is meaningless in this case. This is done with preprocessor guards around the Type 41 members in `struct device` and the code which uses the guarded members. Although the preprocessor usage isn't particularly elegant, adjusting the devicetree syntax and/or grammar depending on a Kconfig option is probably even worse.

This function was only called during multi-processor initialization in ramstage via the init function pointer in the CPU's device operations struct and was run on all cores, so the message on the console was printed once per CPU core. This patch replaces all x86_enable_cache calls by calls to enable_cache and removes the wrapper function and the Kconfig symbol CPU_X86_CACHE_HELPER which was used to only add this when the corresponding CPUs used the x86_enable_cache wrapper function.

2021-10-05arch/x86,cpu/x86: Introduce new method for accessing cpu_infoRaul E Rangel
There is currently a fundamental flaw in the current cpu_info() implementation. It assumes that current stack is CONFIG_STACK_SIZE aligned. This assumption breaks down when performing SMM relocation. The first step in performing SMM relocation is changing the SMBASE. This is accomplished by installing the smmstub at 0x00038000, which is the default SMM entry point. The stub is configured to set up a new stack with the size of 1 KiB (CONFIG_SMM_STUB_STACK_SIZE), and an entry point of smm_do_relocation located in RAMSTAGE RAM. This means that when smm_do_relocation is executed, it is running in SMM with a different sized stack. When cpu_info() gets called it will be using CONFIG_STACK_SIZE to calculate the location of the cpu_info struct. This results in reading random memory. Since cpu_info() has to run in multiple environments, we can't use a compile time constant to locate the cpu_info struct. This CL introduces a new way of locating cpu_info. It uses a per-cpu segment descriptor that points to a per-cpu segment that is allocated on the stack. By using a segment descriptor to point to the per-cpu data, we no longer need to calculate the location of the cpu_info struct. This has the following advantages: * Stacks no longer need to be CONFIG_STACK_SIZE aligned. * Accessing an unconfigured segment will result in an exception. This ensures no one can call cpu_info() from an unsupported environment. * Segment selectors are cleared when entering SMM and restored when leaving SMM. * There is a 1:1 mapping between cpu and cpu_info. When using COOP_MULTITASKING, a new cpu_info is currently allocated at the top of each thread's stack. This no longer needs to happen. This CL guards most of the code with CONFIG(CPU_INFO_V2). I did this so reviewers can feel more comfortable knowing most of the CL is a no-op. I would eventually like to remove most of the guards though. This CL does not touch the LEGACY_SMP_INIT code path. I don't have any way of testing it. The %gs segment was chosen over the %fs segment because it's what the linux kernel uses for per-cpu data in x86_64 mode. BUG=b:194391185, b:179699789 TEST=Boot guybrush with CPU_INFO_V2 and verify BSP and APs have correct %gs segment. Verify cpu_info looks sane. Verify booting to the OS works correctly with COOP_MULTITASKING enabled.

2021-10-01drivers/gic: Remove unnecessary codeJulius Werner
On AArch64 platforms, GIC initialization is generally the job of Trusted Firmware and shouldn't be necessary in coreboot. Only the ancient T210 platform (which was started before we had decided on using Trusted Firmware) calls this code, and even there they have a comment wondering "do we still need this?". I'm just gonna assume (without testing because that board is ancient and I'm lazy) that they don't, and that the TF GIC initialization[1] is sufficient here. Remove this obsolete driver.
