With some debugging in mmc enabled (#define DEBUG at the top of dw_mmc.c
mmc-uclass.c mmc.c rockchip_dw_mmc.c) and CONFIG_MMC_TRACE=y, it gives a
little more information:

Adding Philipp Tomsich to CC.

The not very detailed log of the Debian bug report is at:

  https://bugs.debian.org/898520

v2018.01 works, v2018.03 doesn't, the closest I got to bisecting the
issue:

Any further suggestions would be appreciated.

I tried to bisect this, and got:

commit 04a2ea248f58b3b6216d0cd0a6b8698df8b14355
Author: Jean-Jacques Hiblot 
Date:   Thu Sep 21 16:30:08 2017 +0200

mmc: disable UHS modes if Vcc cannot be switched on and off


But it fails in a slightly different way:

  U-Boot 2018.01-00026-g04a2ea248f (May 21 2018 - 21:46:18 +)

  Model: Firefly-RK3288
  DRAM:  2 GiB
  MMC:   dwmmc@ff0c: 1, dwmmc@ff0f: 0

And just hangs without the "Loading Environment from MMC..."
part...


It is not a trivial revert on top of 2018.05, so I haven't been able to
do that simple test.


CONFIG_ENV_IS_IN_MMC has been enabled since at least:

  5dc4dfd2a94 (Tom Rini2017-08-28 07:16:32 -0400 36)

Same issue with 2018.03+dfsg1-2.

Bug#898520: u-boot-rockchip: firefly-rk3288 hangs on: Loading Environment from MMC

[Vagrant Cascadian]

Package: u-boot-rockchip
Severity: serious
Version: 2018.05+dfsg-1

Booting firefly-rk3288 seems to hang looking for environment:

  U-Boot 2018.05+dfsg-1 (May 10 2018 - 20:24:57 +)
  
  Model: Firefly-RK3288
  DRAM:  2 GiB
  MMC:   dwmmc@ff0c: 1, dwmmc@ff0f: 0
  Loading Environment from MMC...

And just hangs there.

Since this can render a system unbootable, marking as serious.
