2024-05-20Restore patch series "arm: dts: am62-beagleplay: Fix Beagleplay Ethernet"Tom Rini
As part of bringing the master branch back in to next, we need to allow for all of these changes to exist here. Reported-by: Jonas Karlman <jonas@kwiboo.se> Signed-off-by: Tom Rini <trini@konsulko.com>
2024-05-19Revert "Merge patch series "arm: dts: am62-beagleplay: Fix Beagleplay Ethernet""Tom Rini
When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay Ethernet"' I failed to notice that b4 noticed it was based on next and so took that as the base commit and merged that part of next to master. This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35.

2024-03-27acpi: rename aslc_id, aslc_revisionHeinrich Schuchardt
The fields Creator ID and Creator Revision contain information about the tool that created an ACPI table. This may be the ASL compiler for some tables but it is not for others. Naming these fields aslc_id and aslc_revision is misleading. It is usual to see diverse values of Creator ID. On a laptop I saw these: 'AMD ', 'INTL, 'MSFT', 'PTEC'. Obviously not all relate to the Intel ASL compiler. Signed-off-by: Heinrich Schuchardt <heinrich.schuchardt@canonical.com>
2024-01-07acpi: use 64-bit addresses in FADT tableHeinrich Schuchardt
Fields X_FIRMWAE_CTRL and X_DSDT must be 64bit wide. Convert pointers to to uintptr_t to fill these. If field X_FIRMWARE_CTRL is filled, field FIRMWARE must be ignored. If field X_DSDT is filled, field DSDT must be ignored. We should not fill unused fields.

2022-01-25x86: acpi: Split out context creation from base tablesSimon Glass
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 <sjg@chromium.org>

2020-11-06x86: Allow putting some tables in the bloblistSimon Glass
At present all tables are placed starting at address f0000 in memory, and can be up to 64KB in size. If the tables are very large, this may not provide enough space. Also if the tables point to other tables (such as console log or a ramoops area) then we must allocate other memory anyway. The bloblist is a nice place to put these tables since it is contiguous, which makes it easy to reserve this memory for linux using the 820 tables. Add an option to put some of the tables in the bloblist. For SMBIOS and ACPI, create suitable pointers from the f0000 region to the new location of the tables.

For many device types it is possible to figure out the name just by looking at its uclass or parent. Add a function to handle this, since it allows us to cover the vast majority of cases automatically. However it is sometimes impossible to figure out an ACPI name for a device just by looking at its uclass. For example a touch device may have a vendor-specific name. Add a new "acpi,name" property to allow a custom name to be created. With this new feature we can drop the get_name() methods in the sandbox I2C and SPI drivers.
