I ported the cypress ezusb developement kit to sdcc with some extensions to
sdcc-2.2.1.
It take some ideas from the cypress source but assembler parts a now written for
sdcc assembler.
The C-source code is modified to run with sdcc. A lot of things are changed to
use inline assembler.
Include files are updated versions of Tom Sailer.
So at the moment I am not shure if this can be distributed free.
