[Linux-ATM-General] Memory mapping the PHY on CR826

[Alex Zeffertt]

Hi Koen,

Well spotted!  Unfortunately this is not the problem.  I got the base
address and mask the wrong way round in my email but they are the right
way round in my code.  Oops.

I tried your OR8 settings but they didn't work either.  I think there
may be a problem with the addressing on the CR826 board as the PM5350
address line 0 doesn't seem to go anywhere on the schematics!
