The version of mb-gcc on which the microblaze-uclinux-* toolchain was
built, predates the extended FSL operations.  mb-gcc (standalone
version) from most recent EDK of course has these opcodes in it.

So, for now, your best approach is to define macros that emit the raw
opcodes.  Not pretty, but it will get you moving forward.

We are doing a lot of toolchain work in conjunction with the upstream
kernel work (based on gcc-4.1.2 which doe support extended FSL ops).
When it is ready we will also see about releasing a version that is
suitable for the 2.6.20 kernel in petalinux.

Regards,

John
