2023-05-30acpi/acpigen: rename and clarify bus/IO/MMIO resource producer functionsFelix Held
The acpigen_resource_[bus_number,io,mmio*] functions didn't make it very clear that they are generating resource producer ranges and not resource consumer ranges. To clarify this, change the function names to acpigen_resource_producer_[bus_number,io,mmio*] and explicitly add the ADDR_SPACE_GENERAL_FLAG_PRODUCER flag which evaluates to 0, so this doesn't change the functionality.

2023-01-28acpi/acpigen: factor out acpigen_write_processor_namestringFelix Held
This functionality is used in multiple places, so factor it out into a function. Compared to acpigen_write_processor_cnot, the buffer size is decreased from 40 to 16 bytes, but the format string specified by CONFIG_ACPI_CPU_STRING results in 9 chars and a NULL byte which will fit into the buffer without any issue. I've seen the CPU devices being put into another scope within \_SB, but even in that case that would be 14 chars and a NULL byte whist still fits into the 16 byte buffer. For acpigen_write_processor and acpigen_write_processor_package this doesn't change any edge case behavior. In the unrealistic case of the format string resulting in a longer CPU device string, this would have been a problem before this patch too. Also drop the curly braces of the for loop in acpigen_write_processor_package. This makes the code a bit harder to read and isn't a very good idea, but with the curly braces in place, the linter breaks the build :( Signed-off-by: Felix Held <felix-coreboot@felixheld.de> Change-Id: I5d8291a2aaae2011cb185d72c7f7864b6e2220ec Reviewed-on: https://review.coreboot.org/c/coreboot/+/72452 Reviewed-by: Fred Reitberger <reitbergerfred@gmail.com> Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Matt DeVillier <matt.devillier@amd.corp-partner.google.com> Reviewed-by: Elyes Haouas <ehaouas@noos.fr>
