For reference as far as U-Boot goes:

U-Boot 2021.04 (Apr 09 2021 - 17:05:14 +0000)

Model: Pine64 Rock64
DRAM:  4 GiB
PMIC:  RK8050 (on=0x40, off=0x00)
MMC:   mmc@ff500000: 1, mmc@ff520000: 0

It is from a sysutils/u-boot-rock64 build with no
local patches. Previously 2020.10 was in use,
also without problems. (But one of my non-debug
builds of main was in use.)
