On SoCs like DRA7, OMAP5 one cannot enable hypervisor mode directly from the
u-boot because the ROM code puts the chip to supervisor mode after it jumps to boot loader.Patch 1: Introduces a weak function which can be overridden specific to SoCs to switch to hypervisor mode.
Patch 2: overrides weak function in patch 1 switch cpu to hypervisor mode using the available ROM code hook early in the boot phase before the boot loader checks for hypervisor mode on OMAP5 based SoCs.
