You need a later binutils for these instructions - 2.22 works just fine,
even with gcc 4.5.x.


Since we are at it:

Any solution for this one ? omap2plus passes for me.

I have updated my toolchain Assembler (used binutils 2.22 ) with
latest one and issue has fixed.


Not for this build. As I said, the omap2plus build passes for me.
My binutils version is "2.23.1.20121113".

Did you try to build the file after "make allmodconfig" ?
