Dear Benjamin,

This is based on CFG_REMAP_OR_AM. What I need to know is, how do I figure out the right values for CFG_REMAP_OR_AM and PRELIM_OR_AM? I read
We cannot tell you. It is you who defines the memory map of your board.
the README and unfortunately it says nothing (that I understood...). I'm okay with deriving the information, perhaps from the CPU Manual or the Flash Manual or the board's spec, but really, I'm not sure exactly what these values mean. Can someone give me a short explanation?
These are the address masks used in the MPC8xx memory controller.
You will want to read the section about the memory controller in the MPC8xx User's manual.
So you know what kind of hardware I'm dealing with, the basics are an MPC852T CPU with a 16MB Flash: AM29LV320 and SDRAM MT48LC4M32B2.
Sorry, this doesn't help anything. We would need _all_ the nasty little details (probably including the schematics), and then it will become real effort, which you cannot get for free, not even here.
Best regards,
Wolfgang Denk
