Hi,

I tested this on Debian unstable with a slightly patched 7.0.3 kernel [1].
The test branch contains your verisilicon series, Michal's JH7110
display series [2],
and a JH7110 ccache change [3], which was also required to communicate
with the BXE-4-32 firmware [4].

This change here is only used to remove the ugly framebuffer stripes
on the console and in the desktop environment.
