Our ARMv6 do speculative rd for both I and D cache...I'll check with the hardware guys here in ARM and get back to you.
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. -- Catalin
