Hi Kurt,

Sorry for the late reply. I've just managed to apply you patch on top
of ed9a3aa645 and it didn't work for me on 2GB v2.0 rock64 board.

U-Boot TPL 2020.07-rc2-00133-ged9a3aa645-dirty (May 19 2020 - 12:44:16)
LPDDR3, 800MHz
BW=32 Col=10 Bk=8 CS0 Row=15 CS1 Row=15 CS=2 Die BW=16 Size=2048MB
Trying to boot from BOOTROM
Returning to boot ROM...

U-Boot SPL 2020.07-rc2-00133-ged9a3aa645-dirty (May 19 2020 - 12:44:16 +0300)
Trying to boot from MMC1
[and nothing else happens here]

What do you think may be the reason?
