Hi
I came to know, with the MMU always being enabled
it is not possible for the processor to access instructions and data
using a physical addressing during excetion processing
1.Now I want to lock some I/o memory.? (loading locked TLB ENTRIES) after MMu_init
How to do it in the kernel?
2. Is it possible to completely disable the MMU for MPC860T IN LINUX 2.4.20
and use it for custom board
thanks
bharathi
