This amd64-microcode release was based on the linux-firmware tree.
The linux-firmware tree can be found in kernel.org.

It includes AMD-SEV firmware, AMD-UCODE firmware, and AMD-TEE applications
(which are often firmware for other AMD drivers).  The package version is now
based on the linux-firmware release tag that included the newest of any of the
included firmware.

amdtee/ currently includes firmware for the amd_pmf driver.

    amd_pmf: Add initial PMF TA for Smart PC Solution Builder

    AMD PMF driver loads the PMF TA (Trusted Application) into the AMD
    ASP's (AMD Security Processor) TEE (Trusted Execution Environment).

    PMF Trusted Application is a secured firmware placed under
    /lib/firmware/amdtee gets loaded only when the TEE environment is
    initialized. This Firmware adds the initial support for PMF Smart
    PC Solution Builder.
