Can you retry with current trunk (revision 17434 or later) and let me know
if this works now for gcc-4.2, latest binutils and latest kernel-headers?

Thanks,

sorry, no can do.  This was part of a project using the Cirrus EP9315.  Due
to the total lack of support from Cirrus Logic, we switched to another
processor entirely.
