Revision ec8510f6fe57f59e42484809679af31ca7896dcf authored by Lennert Buytenhek on 02 June 2006, 18:51:51 UTC, committed by Russell King on 02 June 2006, 18:51:51 UTC 
[ARM] 3540/1: ixp23xx: deal with gap in interrupt bitmasks
 
Patch from Lennert Buytenhek

On the ixp23xx, the microengine thread interrupt sources are numbered
56..119, but their mask/status bits are located in bit positions 64..127
in the various registers in the interrupt controller (bit positions
56..63 are unused.)

We don't deal with this, so currently, when asked to enable IRQ 64, we
will enable IRQ 56 instead.

The only interrupts >= 64 are the thread interrupt sources, and there
are no in-tree users of those yet, so this is fortunately not a big
problem, but this needs fixing anyway.
