Hi,

The commit: a8011eb84dfac5187cebf00ed8bc981bdb5c1fa1
Author: Olliver Schinagl <oliver at schinagl.nl>

    sunxi: board: Print error after power initialization fails

causes a regression in DRAM init/detection on (at least) the
sunxi H3 nanopi board I have. (The exact board isn't actually
upstream yet, but it's compatible with the nanopi-neo or neo-air)

>>> Good behaviour:
U-Boot SPL 2019.01-rc1-00293-g0c5b0ff71a (Dec 13 2018 - 16:46:41
+0000) DRAM: 512 MiB Trying to boot from FEL <snipped normal FEL
boot output>


>>> Bad behaviour:
U-Boot spl 2019.01-rc1-00101-ga8011eb84d (Dec 13 2018 - 16:44:48
+0000) DRAM: 0 MiB
### ERROR ### Please RESET the board ###


Confirmed the bisection by reverting this patch on current
master.

I'm not expert in this area to know enough about the cause. The
description of the commit sounds perfectly reasonable :)

Cheers,
Karl P
