[PATCH 0/4] hw/arm: Enable 'nested' SMMU in virt, sbsa-ref

[Peter Maydell]

This patchset enables support for nested (two stage) translations
in the SMMU in the virt and sbsa-ref boards.

Patch 1 is Cornelia's compat-machine machinery patch, which we
need to make this change only happen for virt-9.2 and later;
patch 2 is a trivial "missing comment update" change; patches
3 and 4 are the board changes.

Enabling nested support should be transparent to guests, which
will only enable stage 2 if they actually want it.

thanks
