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
