For some reason the wakeup enable bit is not getting set on OMAP2430, OMAP2420. This is inspite of the fact that SYSC_HAS_ENAWAKEUP flag is present in the hwmod database.
I am not sure if there is already a patch to fix this problem. Until the reason is found we need this patch to boot on the above platforms.
