* include/device/device.h: Remove CHIP_NAME() macroNicholas Sudsgaard2024-01-311-1/+1
| | | | | | | | | | | | | | | | | | | | | | | Macros can be confusing on their own; hiding commas make things worse. This can sometimes be downright misleading. A "good" example would be the code in soc/intel/xeon_sp/spr/chip.c: CHIP_NAME("Intel SapphireRapids-SP").enable_dev = chip_enable_dev, This appears as CHIP_NAME() being some struct when in fact these are defining 2 separate members of the same struct. It was decided to remove this macro altogether, as it does not do anything special and incurs a maintenance burden.

| | | | | | | | | | | | | | | | The .inc suffix is confusing to various tools as it's not specific to Makefiles. This means that editors don't recognize the files, and don't open them with highlighting and any other specific editor functionality. This issue is also seen in the release notes generation script where Makefiles get renamed before running cloc.

This can cause timing problems because it's not clear which system should be controlling the GPIO. There's no reason to require explicit disablement however, so drop the superfluous 'disable' flag, and change the _CRS generation to check if the GPIOs will be exported via the 'has_power_resource' flag instead. This mirrors the change made for drivers/i2c/generic. TEST=untested, as no boards selected this option.

* commonlib: Substitude macro "__unused" in compiler.hBill XIE2022-07-141-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | Since there are many identifiers whose name contain "__unused" in headers of musl libc, introducing a macro which expands "__unused" to the source of a util may have disastrous effect during its compiling under a musl-based platform. However, it is hard to detect musl at build time as musl is notorious for having explicitly been refusing to add a macro like "__MUSL__" to announce its own presence. Using __always_unused and __maybe_unused for everything may be a good idea. This is how it works in the Linux kernel, so that would at least make us match some other standard rather than doing our own thing (especially since the other compiler.h shorthand macros are also inspired by Linux).

* drivers/tpm/cr50: Add TPM IRQ timeout Kconfig optionYu-Ping Wu2022-06-081-20/+8
| | | | | | | | | | | | | | | | | | | | | | | The current 10ms timeout for SPI TPM IRQ is not enough for platforms using ti50 (such as corsola). Therefore, introduce a new Kconfig option 'GOOGLE_TPM_IRQ_TIMEOUT_MS'. For platforms using cr50, we need to support legacy pre-ready-IRQ cr50 factory images during the initial boot, so the timeout remains 100ms for I2C TPM and 10ms for SPI TPM. For all the other platforms using ti50, the default timeout is increased to 750ms, as suggested by the ti50 team (apronin@google.com).

This file uses the new tis_vendor_read/write() functions in order to access the cr50 regardless of the bus which is physically used. In order to leave SPI devices intact, the tis_vendor_* functions are added to the SPI driver.
