CAN support for lpc2xxx targets had been written by Uwe Kindler. To add
CAN suppport for the target, you have to implement the eCos interfaces
CYGINT_DEVS_CAN_LPC2XXX_CAN{0,1} for the target. Olpce2294 has not it.
You can look at lpc24xx/ea2468 target for a reference. Certainly, what
Uwe's target has CAN support. It seems for me, you have to tweak the
hal_arm_lpc2xxx_olpce2294.cdl, plf_io.h, olpce2294_misc.c (perhaps and
hal_platform_setup.h), to get CAN support on the target. I'd  not added
same tweaks for olpce2294 platform.
