Newer ARM kernels try to probe for whether the CPU has hardware breakpoint support. For this to work QEMU has to implement a minimal set of the cp14 debug registers. The architecture requires v7 cores to implement debug and so there is no defined way to report its absence; however in practice returning a zero DBGDIDR (ie with a reserved value for "debug architecture version") should cause well-written hw debug users to do the right thing. We also implement DBGDRAR and DBGDSAR as RAZ, indicating no memory mapped debug components.
