[arty] 14400: PowerPC architecture files. Few Mach function are implemented.

by arty＠svn.reactos.com

PowerPC architecture files. Few Mach function are implemented. The biggest things to note here: 1) We have to probe the pci bridge to find out the amount of available memory on older macs. We use the base model boot-time assumption that linux uses and leave it till later to find our max memory. 2) Open firmware proxy functionality is divided in two parts. FreeLDR is responsible for providing data to and getting it from Open firmware in big-endian format in memory. The ofproxy function itself is responsible for shifting the arguments and calling the target big endian function. The good thing here is that we share open firmware functions between the xcoff part and FreeLDR.
