Hi,
as discussed in [1], here is step 2 - idle path errata fixes.
this is the next rev incorporating comments from V2 post
of this series.

Tested:
this series:
       SDP3430
       SDP3630
this series + ASM cleanup series[2]
       SDP3430
       SDP3630
Test Script:

This series + ASM cleanup series[2]:
Tested OK on Beagleboard with full RET and OFF modes,
using cpuidle.

Tested-by: Jean Pihet <redacted>

V2: http://marc.info/?l=linux-omap&m=129106200408109&w=2

Major change in V3:
       Erratas are now handled per silicon - it is much cleaner :)
       no more redundant cpu_is_omap34xx check anymore
       errata configure is __init as it should be
