EBC access

Hi,

I am working on the PPC 405EX processor with a peripheral attached to the EBC. I've requested for I/O memory & mapped it using ioremap. The following are my doubts:

1) How do I ensure that the memory range that I requested is non-cacheable. I've to work with non-cacheable memory. I've requested for memory using request_mem_region( ).
2) Between any consecutive writes or any consecutive reads, if I introduce a delay of 500msec, the read/write is completing. Does this have to do anything with caching? What could be the reason for this?

Any help will be appreciated.

Regards,
Silwer Star
