Something being ported to Cortex-M architecture is a big step but it 
does not mean that it is ported to some hardware, being it  Kinetis, 
STM32, LPC, etc. There's still some work (although not too much) such as 
basic hw initialization, clocking, some serial driver, etc.

This looks promising although information is incomplete, they don't 
mention on what hardware to run uClinux for Kinetis and I guess 
TWR-K60N512 has too little memory. Of course TWR-K70 has more than enough.

I haven't stated that. I merely asked for information on such port. 
Thanks again for information.
