I can't help you with that, but...

I have written a generic driver for the ARM PrimeCell PL022 (which is
the IP block used for the LPC SSP peripheral), but I moved over to using
the STM32 before polishing it up for release.  If you're interested in
picking it up I can let you have it.  From a licensing point of view,
I've just signed and returned the copyright assignment form so it would
be OK to include it in the main tree.
