I'd like to adapt u-boot to work with NFC v3. Do you think it's a
difficult task (and the documentation [1] available should be
sufficient) ?

Sorry I forgot to mention, originally I wasn't using u-boot from
mainline (my tests refer to u-boot from freescale -r9.2) but I'm
switching to use u-boot from mainline on the board so I'm asking here
instead of "freescale's channel". Whenever possible, using a free
software solution is the best solution.
