I spent some more time testing the "U-Boot without LK" changes [1] on DB410c last week and noticed some minor issues that are fixed in this patch series.
Ideally they should be applied on top of [1]. However, actually PATCH 1/3 and PATCH 2/3 are completely unrelated to [1] and could be also applied independently. PATCH 3/3 is likely directly related to [1].
