I am newer to linux.
My board is MPC750+MPC106, and I use MAPB for MPC106.

Due to 106 datasheet,
0x8000,0000 -- 0xFC00,0000 for PCI memory space.

As you know, user space is 0~0xbfff,ffff (3G).
0xc000,0000 ~ 0xffff,ffff(1G) is for kernel.

And my question is:
1) where should I map this address space to ?
2) user application can access this address space directly?
