I tried to bisect this, and got:

commit 04a2ea248f58b3b6216d0cd0a6b8698df8b14355
Author: Jean-Jacques Hiblot <jjhiblot at ti.com>
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 +0000)

  Model: Firefly-RK3288
  DRAM:  2 GiB
  MMC:   dwmmc at ff0c0000: 1, dwmmc at ff0f0000: 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 Rini                2017-08-28 07:16:32 -0400 36) CONFIG_ENV_IS_IN_MMC=y



live well,
