According to this link: http://lists.denx.de/pipermail/u-boot/2014-August/186086.html these SoCs, in particular BCM58622 would belong to the StrataGX network processors: http://www.broadcom.com/products/Processors/Home-and-Small-Business/BCM5862X-Series. > > Do you have some description of the hardware features of this SoC?

It would be really good if all the work you and Rafal did was usable for the Cygnus SoCs. -- Florian
