[U-Boot] 2016.07 regression on Orange Pi PC

[Peter Robinson]

It seems we've regressed with the Orange Pi PC for 2016.07 but I'm
wondering with the PCSI bits whether the process has changed and I've
missed the details of what's needed to flash u-boot.

With rc3 I see the follwing:

U-Boot SPL 2016.07-rc3 (Jul 07 2016 - 10:36:40)
DRAM: u MiB
Could not determine boot source

resetting ...

But with 2016.05 GA I get:

U-Boot SPL 2016.05 (May 30 2016 - 20:15:17)
DRAM: 1024 MiB
Trying to boot from MMC1
