[Message part 6 (text/plain, inline)]

Hi guix!

I'm afraid since commit 3a851d45576e046d696fcf35b34d57b2cd28ea49 [0]
I've not been able to boot from eMMC on the rockpro64 board, it freezes
before loading the kernel. Re-introducing the work-around fixed the
issue for me (see patch attached).

Did we mean to remove the work-around? I'm wondering if there's
something I'm missing, or if I should instead boot from a USB device.

I've also updated u-boot to 2021.07 but I'm seeing the same boot issue
so it doesn't appear to be fixed upstream :-/

Anybody know of any other work around? If not, are you happy with the
patch attached?

Thanks,
Pierre
