Extract the code from the tail end of arm_v7m_do_interrupt() which enters the exception handler into a pair of utility functions v7m_exception_taken() and v7m_push_stack(), which correspond roughly to the pseudocode PushStack() and ExceptionTaken(). This also requires us to move the arm_v7m_load_vector() utility routine up so we can call it. Handling illegal exception returns has some cases where we want to take a UsageFault either on an existing stack frame or with a new stack frame but with a specific LR value, so we want to be able to call these without having to go via arm_v7m_cpu_do_interrupt().

The M profile condition for when we can take a pending exception or interrupt is not the same as that for A/R profile. The code originally copied from the A/R profile version of the cpu_exec_interrupt function only worked by chance for the very simple case of exceptions being masked by PRIMASK. Replace it with a call to a function in the NVIC code that correctly compares the priority of the pending exception against the current execution priority of the CPU.

Despite some superficial similarities of register layout, the M-profile NVIC is really very different from the A-profile GIC. Our current attempt to reuse the GIC code means that we have significant bugs in our NVIC. Implement the NVIC as an entirely separate device, to give us somewhere we can get the behaviour correct. This initial commit does not attempt to implement exception priority escalation, since the GIC-based code didn't either. It does fix a few bugs in passing: * ICSR.RETTOBASE polarity was wrong and didn't account for internal exceptions * ICSR.VECTPENDING was 16 too high if the pending exception was for an external interrupt * UsageFault, BusFault and MemFault were not disabled on reset as they are supposed to be Signed-off-by: NMichael Davidsaver <mdavidsaver@gmail.com> [PMM: reworked, various bugs and stylistic cleanups] Signed-off-by: NPeter Maydell <peter.maydell@linaro.org> Reviewed-by: NAlex Bennée <alex.bennee@linaro.org>

The i.MX timer device can be reset by writing to the SWR bit of the CR register. This has to behave differently from hard (power-on) reset because it does not reset all of the bits in the CR register. We were incorrectly implementing soft reset and hard reset the same way, and in addition had a logic error which meant that we were clearing the bits that soft-reset is supposed to preserve and not touching the bits that soft-reset clears. This was not correct behaviour for either kind of reset. Separate out the soft reset and hard reset code paths, and correct the handling of reset of the CR register so that it is correct in both cases.

In get_page_addr_code(), if the guest PC doesn't correspond to RAM then we currently run the CPU's do_unassigned_access() hook if it has one, and otherwise we give up and exit QEMU with a more-or-less useful message. This code assumes that the do_unassigned_access hook will never return, because if it does then we'll plough on attempting to use a non-RAM TLB entry to get a RAM address and will abort() in qemu_ram_addr_from_host_nofail(). Unfortunately some CPU implementations of this hook do return: Microblaze, SPARC and the ARM v7M. Change the code to call report_bad_exec() if the hook returns, as well as if it didn't have one. This means we can tidy it up to use the cpu_unassigned_access() function which wraps the "get the CPU class and call the hook if it has one" work, since we aren't trying to distinguish "no hook" from "hook existed and returned" any more. This brings the handling of this hook into line with the handling used for data accesses, where "hook returned" is treated the same as "no hook existed" and gets you the default behaviour.

Switch to using qcrypto_random_bytes() rather than rand() as our source of randomness for the BCM2835 RNG. If qcrypto_random_bytes() fails, we don't want to return the guest a non-random value in case they're really using it for cryptographic purposes, so the best we can do is a fatal error. This shouldn't happen unless something's broken, though. In theory we could implement this device's full FIFO and interrupt semantics and then just stop filling the FIFO. That's a lot of work, though, and doesn't really give a very nice diagnostic to the user since the guest will just seem to hang.
