MicroZed PHY timeout

[Richard VanderWal]

Hey Kinsey, 

Thanks for the response. Yes, I am using the 6-freebsd-12 branch of rtems-libbsd. 

This doesn’t make any sense to me, but i get the error when I build everything (rsb, rtems, libbsd) on Redhat Enterprise Linux 8. If I build everything on Ubuntu 22.04, everything works fine.

We have found that the cgem0 interface no longer is initialized and we’re seeing a “phy read timeout: 1” message during boot. This appears to be happening in a call to cgem_miibus_readreg called from cgem_probe.
