Please do yourself a favour and read some docs and FAQ's first.  With
a  low mapping ogf the IMMR like 0x00f00000 you will never be able to

And as mentioned before: the whole memory map is just software. If  it
doesn't fit your needs just change it.

Why don't you have a Linux partition installed so you can be  working
