Hi Ali --
The first four are, as you found, at:
0x00000000
0x01000000
0x04000000
0x05000000
The second set is at:
0xe0000000
0xe1000000
0xe4000000
0xe5000000
There is some discussion of this in the thread starting at:
http://www.freelists.org/archives/linux-cirrus/12-2006/msg00028.html
if you need any additional info.
Good luck, and let us know how your port works out!
Regards, ....... Charlie
