[PATCH v2] ARM: OMAP5: Switch to THUMB mode if needed on secondary CPU

> On my DRA7 system, when the kernel is built in Thumb-2 mode, the secondary CPU
> (Cortex A15) fails to come up causing SMP boot on second CPU to timeout. This
> seems to be because the CPU is in ARM mode once the ROM hands over control to
> the kernel.  Switch to Thumb-2 mode if required once the kernel is control of
> secondary CPU. On OMAP4 on the other hand, it appears to be in Thumb-2 mode on
> entry so this is not required and SMP boot works as is.

> Also corrected a spurious '+' and updated copyright information.
