I've built this tree and have had a play with it, combined with the ATF
from the Github issue and the CONFIG_DRAM_ZQ value mentioned there. Here
are the results so far:
PMIC setup: Success on cold and warm boot, DRAM voltage matches on cold and
warm boot (1.36V).
USB: Controllers show up in dmesg and /sys/bus/usb, but plugging an USB
flash drive into USB1 gives no results. I've not tried USB0.

Ethernet: Interface shows up, with MAC address of all zeroes. Setting to
02:02:02:02:02:02 with 'ip link set dev eth0 address' succeeds. After
setting link up, the interface then appears to receive both broadcast and
unicast packets, confirmed by tcpdump and IPv6 SLAAC assigning an address.
However, transmitted packets appear to be silently dropped on the floor and
do not show up at the other end (checked with tcpdump, direct connection to
my laptop, no difference when connected via a switch).
