[Qemu-devel] [PATCH] vexpress, realview: Add (dummy) L2 cache controller

[Qemu-devel] [PATCH] vexpress, realview: Add (dummy) L2 cache controller

[Peter Maydell]

Instantiate the L2 cache controller on the ARM devboards which have one,
since we have a dummy model of it now. Note that the only non-MP board
with an L2x0 is the PB1176, which we don't model.

Signed-off-by: Peter Maydell <peter.maydell@linaro.org>

This is intended to be applied after the l2x0 implementation patch,
obviously.
