Hi Detlev,
Just a probably dumb side question, but will ATAGS be deprecated once we have the flat device tree also on ARM? As I understand, fdt is certainly the way to go forward, so maybe we can already start with that? In that case, the fdt blob will be another binary blob to be passed to the kernel and as such should be independant of U-Boot. So ideally in U-Boot we have a pointer to the fdt but the fdt itself can be updated independantly.
I also thought about that. But I actually thought that FDT support for ARM isn't ready yet - although I saw much code for it while I worked on ATAGS. How is the FDT-state for ARM? If it is already usable I would be happy to adapt it. But if not I would prefer to stay with ATAGS (as I have a tight schedule for my BA thesis).
Thx for your comment!
Regards Simon
