[evb] 45424: - Define memory map structure for Versatile board/QEMU and send to OS Loader. - Many hack removed. - Better efficency use of memory layout. - Region at 0x800000 now available for FreeLDR use to load kernel files. - Implement simple ArmDiskNormalizeSystemPath so boot is allowed to happen. - Use better stack address as defined in memory map. - Now FreeLDR loads all files correctly from disk and is ready to jump to kernel. ARMv5 paging code must be rewritten before that can happen.

Log:
- Define memory map structure for Versatile board/QEMU and send to OS Loader.
- Many hack removed.
- Better efficency use of memory layout.
- Region at 0x800000 now available for FreeLDR use to load kernel files.
- Implement simple ArmDiskNormalizeSystemPath so boot is allowed to happen.
- Use better stack address as defined in memory map.
- Now FreeLDR loads all files correctly from disk and is ready to jump to kernel. ARMv5
paging code must be rewritten before that can happen.
