[fedora-arm] PCIe slot on Raspberry Pi CM4

I am trying to connect an i210-T1 to the PCIe slot on a Raspberry Pi CM4 with the official IO board. The problem is it won't boot. I tried this in Fedora 38 initially. Now I've installed a recent nightly (Fedora-Server-39-20230828.n.0.aarch64.raw.xz) and I've connected a USB TTL adapter. It appears to be a U-Boot problem. I get the following over and over again
