2024-07-13libpayload: Unconditionally handle "CBMEM_ID_CSE_*" entriesSubrata Banik
This change removes the unnecessary conditional compilation around CBMEM_ID_CSE_BP_INFO and CBMEM_ID_CSE_INFO handling in cb_parse_cbmem_entry. These CBMEM IDs are only relevant on platforms with SOC_INTEL_CSE_LITE_SYNC_BY_PAYLOAD enabled, and platforms without this config option won't encounter these IDs when calling cb_parse_cbmem_entry().

2024-07-11soc/intel/cmn/cse: Refactor CBMEM ID handling for flexibilitySubrata Banik
This patch refactors the handling of CSE CBMEM IDs to enable platforms to choose whether to perform CSE sync operations within coreboot or defer it to the payload. This separation improves code organization, ensuring `cse_lite.c` focuses on coreboot-specific CSE Lite tasks. Now, platforms can select: * `SOC_INTEL_CSE_LITE_SKU` for CSE sync within coreboot * `SOC_INTEL_CSE_LITE_SYNC_BY_PAYLOAD` for deferred payload sync This change ensures mutually exclusive options, avoiding unnecessary SPI flash size increases.

2024-03-19libpayload: gdb: Make die_if() format string a literalJulius Werner
CB:77969 made minor changes to the die_if() macro. One of the consequences is that the format string passed to it can no longer be a real `char *` variable, it needs to actually be a string literal. In the vast majority of call sites that is already the case, but there was one instance in the GDB code where we're reusing the same format string many times and for that reason put it into a const variable. Fix that by turning it into a #define macro instead. (Even though this technically duplicates the format string, the linker is able to merge identical string literals together again, so it doesn't really end up taking more space.)

This patch moves commonlib/stdlib.h -> commonlib/bsd/stdlib.h, since all code is BSD licensed anyway. It also moves some code from libpayloads stdlib.h to commonlib/bsd/stdlib.h so that it can be shared with coreboot. This is useful for a subsequent commit that adds devicetree.c into commonlib. Also we don't support DMA on arm platforms in coreboot (only libpayload) therefore `dma_malloc()` has been removed and `dma_coherent()` has been moved to architecture specific functions. Any architecture that tries to use `dma_coherent()` now will get a compile time error. In order to not break current platforms like mb/google/herobrine which make use of the commonlib/storage/sdhci.c controller which in turn uses `dma_coherent` a stub has been added to arch/arm64/dma.c.

2024-03-13cbfs: Remove broken remnants of PAYLOAD_INFO featureJulius Werner
PAYLOAD_INFO is a very old feature that can add a key/value information section to a payload file. It seems to have only ever been generated by coreinfo and never really read by anything. Since CB:1721 in 2012, the feature has been inadvertently broken in practice since the `.note.pinfo` sections that contain the information get discarded from the payload before cbfstool gets to see them. Since CB:28647 in 2018, support for the section in the SELF loader was (inadvertently?) dropped, so if someone actually fed cbfstool a payload ELF that did have a `.note.pinfo` section, modern coreboot would refuse to boot the payload entirely (which is probably not a good state to leave things in). This patch removes the code to generate PAYLOAD_INFO entries entirely, but leaves the support to parse and extract those sections from old payloads in place in cbfstool.

It seems that we have some applications where we need to calculate a GCD in 64 bits. Now, we could instantiate the algorithm multiple times for different bit width combinations to be able to use the most efficient one for each problem... but considering that the function usually only gets called once per callsite per stage, and that software emulation of 64-bit division on 32-bit systems doesn't take *that* long either, we would probably usually be paying more time loading the second instance of the function than we save with faster divisions. So let's just make things easy and always do it in 64-bit and then nobody has to spend time thinking on which version to call.

2023-06-12libpayload/uhci: Re-write UHCI RH driver w/ generic_hub APINico Huber
This is a complete rewrite of the UHCI root-hub driver, based on the xHCI one. We are doing things by the book as far as possible. One special case is uhci_rh_reset_port() which does the reset se- quencing that usually the hardware would do. This abandons some quirks of the old driver: * Ports are not disabled/re-enabled for every attachment anymore. * We solely rely on the Connect Status Change bit to track changes. * Further status changes are now deferred to the next polling round. The latter fixes endless loops in combination with commit 7faff543da (libpayload: usb: Detach unused USB devices).

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.

Usually submodules are initialized by the top level Makefile.inc, but since this file is never read when building libpayload based payloads outside the main coreboot build, the header cannot be found unless the vboot submodule had previously been initialized.

2022-06-15libpayload/Makefile.payload: Revise config strategyNico Huber
Payloads often just use one of the defconfigs for libpayload. When the `Makefile.payload` was introduced, it also added dependencies to pass a `make oldconfig` or `make defconfig` for the payload on to libpayload. Turned out, this creates some dependency madness when, for instance, `make oldconfig` gets called without a libpay- load `.config` available, or when we try to include the `.config` in the `Makefile`. To make things worse, Kconfig's `Makefile` that is imported from Linux contains some rarely used paths that are generally incompa- tible to our environment. So let's get rid of the hard-to-control automatism. Payloads that don't want to use a libpayload defconfig need to clear the `$(LIBPAYLOAD_DEFCONFIG)` variable and manually run the respective config target to generate a `.config`. To fully support this, the rule to create a `.config` via `defconfig` is guarded by `$(LIBPAYLOAD_DEFCONFIG)`. Otherwise we'd have a spurious, broken recipe when the variable is unset. We keep the option to call libpayload targets with an `lp-` prefix for convenience. The existing, explicit targets `lp-defconfig` and `lp-oldconfig` are replaced with a pattern match, so all config and other targets should work.

2022-05-19coreboot_tables: Add PCIe info to coreboot tableJianjun Wang
Add 'lb_fill_pcie' function to pass PCIe information from coreboot to libpayload, and add CB_ERR_NOT_IMPLEMENTED to the cb_err enum for the __weak function. ARM platform usually does not have common address for PCIe to access the configuration space of devices. Therefore, new API is added to pass the base address of PCIe controller for payloads to access PCIe devices.
