2020-05-02acpi: Move ACPI table support out of arch/x86 (3/5)Furquan Shaikh
This change moves all ACPI table support in coreboot currently living under arch/x86 into common code to make it architecture independent. ACPI table generation is not really tied to any architecture and hence it makes sense to move this to its own directory. In order to make it easier to review, this change is being split into multiple CLs. This is change 3/5 which basically is generated by running the following command: $ git grep -iIl "arch/acpi" | xargs sed -i 's/arch\/acpi/acpi\/acpi/g' BUG=b:155428745 Change-Id: I16b1c45d954d6440fb9db1d3710063a47b582eae Signed-off-by: Furquan Shaikh <furquan@google.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/40938 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: HAOUAS Elyes <ehaouas@noos.fr>

2020-03-18soc: Remove copyright noticesPatrick Georgi
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.

2019-05-16soc/amd/common: Create AcpiMmio functionality from stoneyridgeMarshall Dawson
Move the stoneyridge AcpiMmio code into soc/amd/common. The SB800 southbridge introduced the MMIO hardware blocks at 0xfed80000 commonly known as AcpiMmio. Implementations beginning with Mullins enable decode in PMx04. Older designs use PMx24 and allow for configuring the base address. Future work may support the older version. Comparing the documentation for AMD's RRGs and BKDGs, it is evident that the block locations have not been reassigned across products. In some cases, address locations are deprecated and new ones consumed, e.g. the early GPIO blocks were simpler at offset 0x100 and the newer GPIO banks are now at 0x1500, 0x1600, and 0x1700. Note: Do not infer the definitions within the hardware blocks are consistent across family/model products.
