From: Helge Deller <del...@gmx.de>The physical hardware allows DIMMs of 4 MB size and above, allowing up to 3840 MB of memory, but is restricted by setup code to 3 GB. Increase the limit to allow up to the maximum amount of memory. Btw. the memory area from 0xf000.0000 to 0xffff.ffff is reserved by the architecture for firmware and I/O memory and can not be used for standard memory. An upcoming 64-bit SeaBIOS-hppa firmware will allow more than 3.75GB on 64-bit HPPA64. In this case the ram_max for the pa20 case will change.
