Yes. There is no "porting" with new SBSA/SBBR systems — only fixing bugs and/or adding quirks :)

On FreeBSD for the eMAG, we've had to:

- ignore a wrong value for UART access width https://svnweb.freebsd.org/base?view=revision&revision=34622... (IIRC Ampere did fix the value in the newer FW revisions)

- restore another register after calling EFI runtime services https://svnweb.freebsd.org/base?view=revision&revision=34699...

- fix some PCIe things we were doing wrong https://svnweb.freebsd.org/base?view=revision&revision=34792... https://svnweb.freebsd.org/base?view=revision&revision=34793...

- fix some memory map things https://svnweb.freebsd.org/base?view=revision&revision=34958...
