Subject: board: Arcturus: DM: Disable drivers without DM support.
X-Git-Tag: v2019.07~21^2~10
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=f51d7fc8ce455ef201f86e1fab4d380444b96789;p=oweals%2Fu-boot.git

board: Arcturus: DM: Disable drivers without DM support.

Extra "not DM" controllers support is disabled.
u-boot BSP still good enough to upgrade and run images.
