armv7m: MRS/MSR: handle unprivileged access
The MRS and MSR instruction handling has a number of flaws: * unprivileged accesses should only be able to read CONTROL and the xPSR subfields, and only write APSR (others RAZ/WI) * privileged access should not be able to write xPSR subfields other than APSR * accesses to unimplemented registers should log as guest errors, not abort QEMU Signed-off-by: Michael Davidsaver <mdavidsaver@gmail.com> Reviewed-by: Peter Maydell <peter.maydell@linaro.org> Message-id: 1484937883-1068-2-git-send-email-peter.maydell@linaro.org [PMM: rewrote commit message] Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
