so the the mcf5474 utilizes SEC h/w version 1.1 (or a variant thereof),
with which the talitos driver is currently incompatible. Even if
you've managed to fake the device tree node properties, the driver has
the master reset bit in a different position than the one on the
mcf547x, so it doesn't even know how to reset the device properly.
you might try entering a ticket with the freescale coldfire support
web - who knows, they might be willing to assist you in porting the
driver to handle sec h/w versions < 2.0. AFAIK, various registers,
various bits within registers, and the descriptor submission method
differ in the h/w, and the driver needs to double as a platform
driver for coldfire arch.
