2024-08-06drivers/{crb,pc80/tpm}: Drop conflicting tpm_config_t typedefMichał Żygowski
When both CRB and pc80 TPM drivers are compiled in, building fails because the tpm_config_t typedef has two incompatible definitions. Given that typedefs are discouraged by the project's coding style, simply get rid of the tpm_config_t typedef. TEST=Compile MSI PRO Z690-A target with CRB and PC80 TPM chips enabled in devicetree.

2024-04-26drivers/pc80/tpm: Disable device if TPM not presentMichał Żygowski
If the TPM is not detected in the system it may mean it is inactive due to enabled ME with active PTT. In such case, the chipset will route the TPM traffic to PTT CRB TPM on Intel systems. If TPM is not probed, disable the PC80 TPM device driver, so that coreboot will not generate improper SSDT ACPI table.

This prepares the code for enabling both CONFIG_TPM1 and CONFIG_TPM2 during compilation, in which case actual TPM family in use can be determined at runtime. In some places both compile-time and runtime checks are necessary. Yet in places like probe functions runtime state checks don't make sense as runtime state is defined by results of probing.

2024-01-31include/device/device.h: Remove CHIP_NAME() macroNicholas Sudsgaard
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.

2021-10-25drivers/pc80/tpm: Use stopwatch for timeout-loopsWerner Zeh
There are manual timeout-loops which use a fixed value and udelay(). In all cases there is a debug printk() inside this loop which, when enabled, takes way longer than the counted microsecond delay. This leads to the result that e.g. a 1 second delay takes nearly an eternity if the debug messages are enabled due to the longer function execution time. This patch uses the stopwatch scheme for the timeout-loops which still makes sure that the timeout period is maintained while it takes longer function calls like printk() into account. In order to keep the minimum delay between two register accesses on the TPM keep the udelay(1)-call. TEST=Enable TPM debug messages on a board where the TPM hits a timeout by failure and make sure that the debug messages occur in the log just in the timeout period. It still works as expected if the debug messages are disabled.

2020-04-02Trim `.acpi_fill_ssdt_generator` and `.acpi_inject_dsdt_generator`Nico Huber
These two identifiers were always very confusing. We're not filling and injecting generators. We are filling SSDTs and injecting into the DSDT. So drop the `_generator` suffix. Hopefully, this also makes ACPI look a little less scary.

2020-01-09acpi: Be more ACPI compliant when generating _UIDPatrick Rudolph
* Add function to generate unique _UID using CRC32 * Add function to write the _UID based on a device's ACPI path ACPI devices that have the same _HID must use different _UID. Linux doesn't care about _UID if it's not used. Windows 10 verifies the ACPI code on boot and BSODs if two devices with the same _HID share the same _UID. Fixes BSOD seen on Windows 10.

Certain TPMs (observed on Infineon SLB9635 installed on revolve 810 g1) seem to need some delay between tis_wait_valid() and tis_has_valid_data(), or tis_has_valid_data() may invalidly return 0, ending the loop immaturely with some bytes left unread, and fail to pass the check below, causing the current command not finalized by tis_command_ready(), and blocking any later tis_wait_ready(). This time the added delay is controlled by a Kconfig option TPM_RDRESP_NEED_DELAY.
