From: Andrew Jeffery <andrew@aj.id.au>

[ Upstream commit ded3e2864c735f33ba5abbbe2d7b1c6605242f9b ]

The values were determined via scope measurements.

With the patch we can write and read data without issue where as booting
the system without the patch failed at the point of mounting the rootfs.
