ARM: dts: rockchip: reserve unusable memory region on rk3288
From: Heiko Stuebner <heiko@...> Date: Sat, 1 Aug 2015 13:00:49 +0200
Commit-Message
The rk3288 has problems accessing the memory region 0xfe000000~0xff000000. So block off the affected region to prevent its use. Tested on 4GB Veyron Minnie and 2GB Veyron Jerry devices. Signed-off-by: Heiko Stuebner <heiko@...>
