--- Comment #17 from Richard Earnshaw <rearnsha at gcc dot gnu.org> ---
OK, I've found the erratum number, it's 720247; but it's specific to the
11MPcore and is fixed in r2p1 silicon.

The erratum workaround description states that there is *no* robust software
fix when the MMU is disabled.  Some hardware fixes on your platform might be
possible, but are off-topic here.  Also, using r2p1 silicon fixes the problem.

Either way, there's nothing we can do in GCC to address this, given the nature
of the problem.
