Re: FW: eCos for MPC55xx

[Ilija Koco <ilijak at siva dot com dot mk>]

Hi Jochen

Nice thing
I recently ported eCos to MAC7100 that has same serial port that i
placed in directory dev/serial/freescale. i tried to meke it platform
independent so maybe you coul'd consolidate it with your's.

I haven't checked CAN but it they are same you coul'd place it under
some general dir so it coul'd seamlessly fit with mac7100 (and possibly
other freescale chips).

regards
Ilija
