This commit enables the work done in commit ef52605e for the A20-OLinuXino_MICRO{,-eMMC} boards. It was previously used only for the A20-OLinuXino-Lime2{,-eMMC} boards but is also needed for the MICRO boards. Without this, the board consistently hangs upon reboot. Note that a cold boot works fine though.
I don't have -eMMC board variant to double check but the quirk is most likely present as well so I patched configs/A20-OLinuXino_MICRO-eMMC_defconfig too.
The issue occurs with revision G of the board and most likely previous revisions as well since the faulty capacitance on LDO3's output hasn't been modified since the initial release of the board.
Many thanks to Marex in #u-boot @ irc.freenode.net for helping me debugging this. --- configs/A20-OLinuXino_MICRO-eMMC_defconfig | 1 + configs/A20-OLinuXino_MICRO_defconfig | 1 + 2 files changed, 2 insertions(+)
