tpm: fix the conditional for the arm64 build

2025-11-15T02:22:15Z

The intention was clearly that these ACPI bits would be included for arm64, but MACHINE_ARCH there is aarch64 -- correct the minor typo to build everything that should be there. Fixes: c2e9c5bbf0229 ("tpm: Refactor TIS and add a SPI attachment")

Remove residual blank line at start of Makefile

This is a residual of the $FreeBSD$ removal. MFC After: 3 days (though I'll just run the command on the branches) Sponsored by: Netflix

tpm: Fix standalone build

2024-06-25T05:34:59Z

We're building ACPI, so we need -DDEV_ACPI on CFLAGS. Nomally, the kernel config brings this in, but there's no kernel directory for the standalone build. Sponsored by: Netflix

tpm: Refactor TIS and add a SPI attachment

2024-05-03T20:26:11Z

Summary: Though mostly used in x86 devices, TPM can be used on others, with a direct SPI attachment. Refactor the TPM 2.0 driver set to use an attachment interface, and implement a SPI bus interface. Test Plan: Tested on a Raspberry Pi 4, with a GeeekPi TPM2.0 module (SLB9670 TPM) using security/tpm2-tools tpm2_getcaps for very light testing against the spibus attachment.
