ARM: 6768/1: hw_breakpoint: ensure debug logic is powered up on v7 cores ARMv7 allows the debug core logic to be powered down and provides the DBGPRSR register so that software can power-up and check the status of the logic. This patch ensures that the debug logic is powered up on ARMv7 cores before we attempt to access the extended debug registers.
