[U-Boot] [PATCH v1 2/9] arm: mvebu: Add Serdes PHY config code
Stefan Roese
sr at denx.de
Tue Oct 28 10:36:01 CET 2014
This code is ported from the Marvell bin_hdr code into mainline
SPL U-Boot. It needs to be executed very early so that the devices
connected to the serdes PHY are configured correctly.
