2024-03-23soc/amd/*/memmap: factor out common read_lower_soc_memmap_resourcesFelix Held
Since the code for reporting the memory map below cbmem_top is basically identical for all non-CAR AMD SoCs, factor this out into a common read_lower_soc_memmap_resources implementation.

2024-02-01soc/amd: factor out memmap from root_complexFelix Held
Now that the SoC-specific memory map is reported on the domain device instead of the northbridge device, factor out the read_soc_memmap_resources function from root_complex.c to new memmap.c file. For now each SoC still has its own memmap.c file, but the plan is to eventually have a common implementation that works for all AMD family 17h+ SoCs. For that I'll still need to look closer into the differences between the FSP and the openSIL integration though.

2020-06-13soc/amd/picasso: Place early stages and data buffers at the bottom of DRAMFurquan Shaikh
This change updates memlayout.ld for Picasso to place all early stages (bootblock, romstage, FSP-M, verstage) and data buffers (vboot workbuf, APOB, preram-cbmem console, timestamp, early BSP stack) at the bottom of DRAM starting at 32MiB. This uses static allocation for most components by defining Kconfig variables for base and size. It relies on the linker to complain if any of the assumptions are broken. This also allows romstage to use linker symbols for _early_reserved_dram and _eearly_reserved_dram to store information in CBMEM about the early DRAM usage by coreboot before ramstage starts execution. This allows ramstage to reserve this memory region in BIOS tables so that S3 resume can reuse the same space without corrupting OS memory.

2020-05-01soc/amd/picasso: Add FSP support for including AGESAMarshall Dawson
AMD has rewritten AGESA (now at v9) for direct inclusion into UEFI build environments. Therefore, unlike the previous Arch2008 (a.k.a. v5), it can't be built without additional source, e.g. by combining with EDK II, and it has no entry points for easily building it into a legacy BIOS. AGESA in coreboot now relies on the FSP 2.0 framework published by Intel and uses the existing fsp2_0 driver. * Add fsp_memory_init() to romstage.c. Although Picasso comes out of reset with DRAM alive, this call is added to maximize compatibility and facilitate internal development. Future work may look at removing it. AGESA reports the memory map to coreboot via HOBs returned from fsp_memory_init(). * AGESA currently sets up MTRRs, as in most older generations. Take ownership back immediately before running ramstage. * Remove cbmem initialization, as the FSP driver handles this. * Add chipset_handle_reset() for compatibility. * Top of memory is determined by the FSP driver checking the HOBs passed from AGESA. Note that relying on the TOM register happens to be misleading when UMA is below 4GB.

They're listed in AUTHORS and often incorrect anyway, for example: - What's a "Copyright $year-present"? - Which incarnation of Google (Inc, LLC, ...) is the current copyright holder? - People sometimes have their editor auto-add themselves to files even though they only deleted stuff - Or they let the editor automatically update the copyright year, because why not? - Who is the copyright holder "The coreboot project Authors"? - Or "Generated Code"? Sidestep all these issues by simply not putting these notices in individual files, let's list all copyright holders in AUTHORS instead and use the git history to deal with the rest.
