From: Andrew Jeffery <andrew@xxxxxxxx> commit 2d6608b57c50c54c3e46649110e8ea5a40959c30 upstream. The degree values were reversed out from the magic tap values of 7 (in) and 15 + inversion (out) initially suggested by Aspeed. With the patch tacoma survives several gigabytes of reads and writes using dd while without it locks up randomly during the boot process.
