Processor microcode updates provide bug fixes, which can be critical to
the security and stability of your system. This port uses the cpuctl(4)
microcode update facility to keep your AMD processor's firmware
up-to-date.
sysutils/cpu-microcode-amd: Update to 2025-12-02 snapshot
Update AMD CPU microcode for processor families 19h and 1ah.
From upstream's README:
NOTE: In order to not fully abandon machines affected by AMD-SB-7033 [1]
that have not received the BIOS update, the family 19h microcode
container now includes a second patch for these machines that brings the
microcode to the highest possible level without the microcode signing
fix. While a BIOS update is highly recommended to receive the latest
security updates issued after the microcode signing vulnerability, this
will allow non-updated systems to at least receive some microcode
updates beyond the version provided by BIOS.

sysutils/cpu-microcode*: support early loading of AMD ucode
Install the AMD ucode in /boot/firmware for early loading just like
is done for intel. Update the instructions for early loading to
reflect that AMD is now supported too.

sysutils/cpu-microcode-*: Reorganize CPU microcode ports
Prior to this update, sysutils/devcpu-data, which only contained an RC
script, had run dependencies on the AMD and Intel microcode ports. This
made it cumbersome to have just the AMD or just the Intel microcode
ports installed. With this change, the microcode ports now depend on
the RC script.
Other changes:
- Use more intuitive port names: cpu-microcode, cpu-microcode-amd,
cpu-microcode-intel, and cpu-microcode-rc.
- Add the metaport, cpu-microcode, which pulls in all related ports.
