Subject: [PATCH 1/2] ARM: dts: rockchip: reserve unusable memory region on rk3288
Date: Sat, 01 Aug 2015 14:35:18 +0200 [thread overview]
Message-ID: <15143985.aGzb1oeyb9@diego> (raw)
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-4mtYJXux2i+zQB+pC5nmwQ@public.gmane.org>
