I have mpc85xx hardware, mostly access points adapted from the
P1020WLAN board, but I am frankly a hobbyist. I do my work under
OpenWrt, and I have no relationship with the manufacturers of these
devices.

I only catch regressions on my boards when changes are backported to
the LTS kernel OpenWrt uses (so, presently, 5.15).
