Just for clarification - is your ARMv6 MP processor an ARM11MPCore or
your own MP variant?

In case of Cortex-A9 (ARMv7), the TRM states clearly that it can do
speculative loads into the L1 D-cache and this can be disabled via a bit
in the auxiliary control register. Do you have a similar bit on your
ARMv6 MP processor?

Thanks.
