The problem about MMU in MPC860

[LiuTao]

Hi:

This is really a boring problem, however, give me some
help please.
I am debugging the linux on my customized 860 board.
The linux can't bootup, the message in log_buf is:

Couldn't find 4096 bytes at 4096 alignment

When the program did map_page() in __ioremap(),
the problem happened.

Something wrong?
How to resolve it?
Any suggestion is welcome.

Thanks!

LiuTao
