Iglesias" , qemu-arm@nongnu.org, patches@linaro.org This patchset fixes or implements a lot of traps to EL3 as listed in the ARM ARM section D1.15.4 "EL3 configurable controls". Most of the rest we already had implemented. NB: where the trap I was implementing for EL3 had an obvious equivalent in EL2 I included the EL2 check in this series, but I haven't attempted to implement traps which are only EL2 and not EL3. The remaining traps I haven't done yet are: * MDCR_EL3.TPM -- easy (similar to TDOSA/TDRA/TDA) but will conflict with the perf monitor fixes currently on list, so I haven't done it yet * SRS using R13_mon * changing to monitor via CPS/MSR/exc return -- both of these require us to tighten up our handling of bogus mode specifications in various places in 32-bit code translation. I'll do this next, but it isn't really very similar to these patches which are mostly sysreg access traps, so different patchset. The patchset assumes you've already applied the ones I have on list at the moment (notably including the patch that adds the isread parameter to system register access functions).
