I see no difference between Starlight and Visionfive boards, both fail
the same way.

I also see that sometimes the firmware greeting from brcmfmac occurs
_after_ the timeout error from hci0:

# journalctl -b -2 | grep -e brcmf_c_preinit_dcmds -e hci0:
May 16 12:01:54 beaglev kernel: Bluetooth: hci0: command 0x1001 tx timeout
May 16 12:01:54 beaglev kernel: Bluetooth: hci0: BCM: Reading local version info failed (-110)
May 16 12:01:54 beaglev kernel: brcmfmac: brcmf_c_preinit_dcmds: Firmware: BCM43430/1 wl0: Mar 30 2021 01:12:21 version 7.45.98.118 (7d96287 CY) FWID 01-32059766

Is this perhaps a race with the firmware loading?
