acpi: Move MCFG implementation to common lib

2022-02-09T19:30:13Z

MCFG tables are used on multiple arches. Move to common ACPI lib. Cc: Simon Glass Signed-off-by: Moritz Fischer Reviewed-by: Simon Glass Use sizeof(*mcfg) instead of sizeof(*header) Signed-off-by: Simon Glass

x86: Move CSRT table to a writer function

2022-01-25T18:44:36Z

Move this table over to use a writer function, moving the code from the x86 implementation. Signed-off-by: Simon Glass

x86: Move SSDT table to a writer function

2022-01-25T18:44:36Z

Move this table over to use a writer function, moving the code from the x86 implementation. Signed-off-by: Simon Glass

x86: Move DSDT table to a writer function

2022-01-25T18:44:36Z

Move this table over to use a writer function, moving the code from the x86 implementation. Add a pointer to the DSDT in struct acpi_ctx so we can reference it later. Disable this table for sandbox since we don't actually compile real ASL code. Signed-off-by: Simon Glass

x86: Move FACS table to a writer function

2022-01-25T18:44:36Z

Move this table over to use a writer function, moving the code from the x86 implementation. Add a pointer to the DSDT in struct acpi_ctx so we can reference it later. Signed-off-by: Simon Glass

x86: Move base tables to a writer function

2022-01-25T18:44:36Z

Use the new ACPI writer to write the base tables at the start of the area, moving this code from the x86 implementation. Signed-off-by: Simon Glass

x86: acpi: Split out context creation from base tables

2022-01-25T18:44:36Z

At present acpi_setup_base_tables() both sets up the ACPI context and writes out the base tables. We want to use an ACPI writer to write the base tables, so split this function into two, with acpi_setup_ctx() doing the context set, and acpi_setup_base_tables() just doing the base tables. Disable the writer's write_acpi_tables() function for now, to avoid build errors. It is enabled in a following patch. Signed-off-by: Simon Glass

acpi: Use finer-grained control of ACPI-table generation

2022-01-25T18:44:36Z

Rather than keying everything off ACPIGEN, use the main GENERATE_ACPI_TABLE option to determine whether the core ACPI code is included. Make sure these option are not enabled in SPL/TPL since we never generate tables there. Signed-off-by: Simon Glass

acpi: Support writing Device Properties objects via _DSD

2020-07-17T06:32:24Z

More complex device properties can be provided to drivers via a device-specific data (_DSD) object. To create this we need to build it up in a separate data structure and then generate the ACPI code, due to its recursive nature. Add an implementation of this.

acpi: Support generation of ACPI code

2020-07-17T06:32:24Z

Add a new file to handle generating ACPI code programatically. This is used when information must be dynamically added to the tables, e.g. the SSDT. Initial support is just for writing simple values. Also add a 'base' value so that the table can be freed. This likely doesn't happen in normal code, but is nice to do in tests.
