That would be Christian Hohnstaedt <chohnstaedt at innominate.com>'s driver
which is (afaik) in mainstream by now, and  
Krzysztof Halasa <khc at pm.waw.pl>'s driver, which is newer. There's a discussion
about these drivers on linux-arm-kernel. 

Getting either of those drivers fixed up and pushed to u-boot would be great. Of
course, one will still need to put the microcode somewhere else due to licencing,
but that's a minor matter.
