After a lot research about the device tree and fiddling around with dts files I also managed to get the four sata ports and dual gigabit ports to work. There is a second sata controller on the PCI bus, and the ethernet interfaces had to be configured based on a very old kernel patch I found online that never made it into the kernel (http://lists.infradead.org/pipermail/linux-arm-kernel/2009-November/003906.html)
