OK I will see what kind of information I can gather and which ones I can add to the Documentation/arm/Marvell/README file. My current understanding is that there are at least 3 kind of CPU: PJ4, PJ4B and PJ4B-MP and all of them belongs to the Sheeva family. > > Arnd > -- Gregory Clement, Free Electrons Kernel, drivers, real-time and embedded Linux development, consulting, training and support. http://free-electrons.com
