OMAP3630: PM: Erratum i608: disable RTA
Erratum id: i608 RTA (Retention Till Access) feature is not supported and leads to device stability issues when enabled. This impacts modules with embedded memories on OMAP3630 Workaround is to disable RTA on boot and coming out of core off. For disabling RTA coming out of off mode, we do this by overriding the restore pointer for 3630 as the first point of entry before caches are touched and is common for GP and HS devices. To disable earlier than this could be possible by modifying the PPA for HS devices, but not for GP devices.
