This is amazing!
I can help with the waf integration. I'm working on making the waf
system in rtems-lwip better, so that it doesn't take much effort to
integrate a new set of drivers like this.

Great!
It would be great to get it tested on a hardware after it's ported on
rtems-lwip.

I'm following the OMK repository for TMS570. After the waf support is
added with the STM32 and LPC, It should be possible to merge the
driver updates from omk.
