Subject: [PATCH] ARM: dts: rockchip: Reserve unusable memory region on rk3066
Date: Sat, 1 Oct 2016 16:09:39 +0200 [thread overview]
Message-ID: <20161001140939.GA31220@vaio-ubuntu> (raw)
For some reason accessing memory region above 0xfe000000 freezes
system on rk3066. There is similiar bug on later rockchip soc (rk3288)
solved same way.
