[Qemu-devel] [PATCH 0/6] target-arm: Implement various EL3 traps

[Peter Maydell <peter.maydell@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).
