[U-Boot] [PATCH v1 09/12] arm: mvebu: Add Armada 38x SERDES / PHY init code from Marvell bin_hdr
Stefan Roese
sr at denx.de
Wed Jun 3 11:18:28 CEST 2015
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.
