ARMv7: Enable the SWP instruction The SWP instruction has been deprecated starting with the ARMv6 architecture. On ARMv7 processors with the multiprocessor extensions (like Cortex-A9), this instruction is disabled by default but it can be enabled by setting bit 10 in the System Control register. Note that setting this bit is safe even if the ARMv7 processor has the SWP instruction enabled by default. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
