OK, great.  That patch is basically a revert of 
a819c4f16d5a2708c11e708fd59a96565c5384a8 ("ARM: OMAP3: PM: Only access IVA 
if one exists").  Sounds like we need to discriminate between the case 
where the IVA2 is present but has been efused off in some way (as in the 
AM3703) vs. the case where the IVA2 is not present at all (as in the 
AM35xx).

Mark, do you have the time to take a look at this?  Maybe omap3_has_iva() 
needs to be split into omap3_has_iva() and omap3_has_usable_iva().  Or 
maybe you can come up with a better idea...
