Subject: km_arm: enable POST for these boards
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=a2da616311151ecfab8b8fcc510686fc3c0c9a21;p=project%2Fbcm63xx%2Fu-boot.git

km_arm: enable POST for these boards

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.
