They are used for Oct= eon chips, for U-Boot to tell the kernel about physical memory at startup. = I need to synthesize one, and there is effectively no documentation at all = on the format. Looking at the U-Boot code is extremely difficult to make an= y sense of. I'm hoping someone has a simple description of the layout I can= work with. Failing that, if someone is using Octeon evaluation boards and U-Boot with = -CURRENT, perhaps they would run some test code for me? ...................................
