acpi: Write pointers to tables instead of addresses 2024-01-07T20:45:07+00:00 Simon Glass sjg@chromium.org 2023-12-31T15:25:54+00:00 a8efebe71978b3b21e04c7f104987ada879e0800 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.
