From: Aidan <[email protected]> Enable SPI, TPM, and wolfTPM support in the Raspberry Pi 4 default configuration for out-of-the-box TPM 2.0 support with Infineon SLB9670/9672 TPM HATs.
SPI support: CONFIG_SPI, CONFIG_DM_SPI, CONFIG_BCM2835_SPI, CONFIG_CMD_SPI Enables the BCM2835 hardware SPI driver. Soft SPI is disabled since the hardware driver is used. TPM and wolfTPM: CONFIG_TPM, CONFIG_TPM_V2, CONFIG_CMD_TPM: core TPM support CONFIG_TPM_WOLF: wolfTPM library integration CONFIG_CMD_WOLFTPM: wolfTPM command backend for tpm2 CONFIG_WOLFTPM_SLB9672: Infineon SLB9672 chip support WOLFTPM_LINUX_DEV disabled: uses native wolfTPM TIS layer with direct SPI communication rather than U-Boot's TPM driver model Logging: CONFIG_LOG with level 7 (DEBUG) to enable log_debug() output from wolfTPM commands. Testing: CONFIG_UNIT_TEST, CONFIG_CONSOLE_RECORD, CONFIG_HEXDUMP for running the wolfTPM C unit test suite.
