ARM: OMAP5: Add the WakeupGen IP updates OMAP4 and OMAP5 share same WakeupGen IP with below few udpates on OMAP5. - Additional 32 interrupt support is added w.r.t OMAP4 design. - The AUX CORE boot registers are now made accessible from non-secure SW. - SAR offset are changed and PTMSYNC* registers are removed from SAR. Patch updates the WakeupGen code accordingly. Signed-off-by: R Sricharan <r.sricharan@ti.com> Signed-off-by: Santosh Shilimkar <santosh.shilimkar@ti.com>

ARM: OMAP4: PM: Add WakeupGen and secure GIC low power support Add WakeupGen and secure GIC low power support to save and restore it's registers. WakeupGen Registers are saved to pre-defined SAR RAM layout and the restore is automatically done by hardware(ROM code) while coming out of MPUSS OSWR or Device off state. Secure GIC is saved using secure API and restored by hardware like WakeupGen.
