--- Comment #1 from Scott wood <scottwood at freescale dot com> ---
Decorated storage (lbdx and such) requires cache-inhibited memory, and the
operations are defined by each SoC rather than by the e6500 core -- this makes
it unusable by GCC. The non-decorated l[bh]arx/st[bh]cx. could be used,
though.
