[U-Boot-Users] RE: More On Memory Bank x (nothingness)?

[Vladimir Gurevich]

Jerry,

I guess the point is EXACTLY to have a CS, which doesn't have anything 
connected to it. The idea is to use a certain address space, which is
cached. Thus, you don't have to have real memory there, it is all 
in the cache anyway. They chose CS4 to make sure that even if something 
goes to the bus, there are no unpleasant side effects, since CS4 is not used.

As I said in the previous email, I also had some problems using this
piece of code and quickly moved on to use OCM, just because I knew that
another bootloader used it anyway.

Happy hacking,
Vladimir
