2025-04-03acpi: Support checking checksumsSimon Glass
When the ACPI tables come from an earlier bootloader it is helpful to see whether the checksums are correct or not. Add a -c flag to the 'acpi list' command to support that. Signed-off-by: Simon Glass <sjg@chromium.org>

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: Write pointers to tables instead of addressesSimon Glass
Sandbox uses an API to map between addresses and pointers. This allows it to have (emulated) memory at zero and avoid arch-specific addressing details. It also allows memory-mapped peripherals to work. As an example, on many machines sandbox maps address 100 to pointer value 10000000. However this is not correct for ACPI, if sandbox starts another program (e.g EFI app) and passes it the tables. That app has no knowledge of sandbox's address mapping. So to make this work we want to store 10000000 as the value in the table. Add two new 'nomap' functions which clearly make this exeption to how sandbox works. This should allow EFI apps to access ACPI tables with sandbox, e.g. for testing purposes. Signed-off-by: Simon Glass <sjg@chromium.org> Suggested-by: Heinrich Schuchardt <xypron.glpk@gmx.de>

2023-12-13cmd: acpi: fix acpi list commandHeinrich Schuchardt
ACPI tables may comprise either RSDT, XSDT, or both. The current code fails to check the presence of the RSDT table before accessing it. This leads to an exception if the RSDT table is not provided. The XSDT table takes precedence over the RSDT table. The return values of list_rsdt() and list_rsdp() are always zero and not checked. Remove the return values. Addresses in the XSDT table are 64-bit. Adjust the output accordingly. As the RSDT table has to be ignored if the XSDT command is present there is no need to compare the tables in a display command. Anyway the specification does not require that the sequence of addresses in the RSDT and XSDT table are the same. The FACS table header does not provide revision information. Correct the description of dump_hdr(). Adjust the ACPI test to match the changed output format of the 'acpi list' command.
