Allow other architectures to use acpi_create_mcfg_mmconfig as well
by moving the function prototype to common code.

acpi: x86: Move MADT to common code

2024-10-27T23:12:44+00:00

Write MADT in common code and let the SoC fill out the body by
calling acpi_fill_madt() which must be implemented at SoC level.

acpi: x86: Write FADT in common code

2024-10-27T23:12:44+00:00

Write the FADT in common code since it's used on all architectures.
Since the FADT is mandatory all SoCs or mainboards must implement the
introduced function acpi_fill_fadt() and properly update the FADT.

acpi: x86: Move SPCR and DBG2 into common code

2024-10-27T23:12:44+00:00

This moves the SPCR and DBG2 table generation into common code, so that
they can be used by architectures other than x86.

acpi: move acpi_get_rsdp_addr() to acpi/acpi_table.h

2023-12-13T23:39:05+00:00

Function acpi_get_rsdp_addr() is needed on all architectures which
write ACPI tables. Move the definition from the x86 include to an
architecture independent one.

Reland "x86: Move FACP table into separate functions""

2023-09-21T22:03:46+00:00

Each board has its own way of creating this table. Rather than calling the
acpi_create_fadt() function for each one from a common acpi_write_fadt()
function, just move the writer into the board-specific code.

As a result Linux kernel can't find mandatory tables and fails
to boot.

Hence, revert it for good.

x86: acpi: Update acpi_fill_csrt() to use acpi_ctx

2022-01-25T18:44:36+00:00

Update this function to the newer style, so we can avoid passing and
returning an address through this function.

Also move this function out of the x86 code so it can be used by other
archs.
