[U-Boot] [PATCH 8/8] km_arm: enable POST for these boards

[Valentin Longchamp]

The current km_arm boards have a Power-On test jumper. When this
jumper is set, this triggers some Power-On tests on the board.

This patch enables the support of this jumper for starting the
memory_regions test when the jumper is set.
