Details

AMD ucode now like Intel ucode needs to be loaded from a separate early initrd to avoid a late load.
Related warning message "CPU features have changed after loading microcode, but might not take effect." [1]
[2] contains upstream's example of how to generate an appropriate initrd. Such a script could also be added to linux-firmware.

I can do these steps in build.sh, but maybe is better to have a package for amd_ucode.bin.

Please test. Thanks.

Yes it may be better to have a ucode package that either generates or provides a combined ucode initrd or just the amd one.

oops, I just tested and fixed it.

Builds and compiled transferred to usb as per wiki instructions:
Intel EFI systemd-boot no issues system still applies microcode update
Intel BIOS syslinux firmware will not boot media this is an issue with my system.
I currently do not have access to an AMD system to test.

Thanks. I will push the patch and release a new archiso next weekeed for next iso snapshot.
