I am currently writing a bootloader for the EBSA-285 board,
containing a StrongARM processor. All is looking good,
except that I need to map the 1st 4 megs of memory from
0x00000000 to 0xf0000000, with the rest of memory and the
CSR's mapped 1:1 physical to virtual. I don't have any idea
how to do this - I know I have to write the 1st and 2nd
level tranlastion tables somehow, but I don't know where
these reside in memory, and what to write to them. Any help
would be greatly appreciated....
