Anyone ever tried to use the Random Number Generator on the MPC8541E?
I can't get it to behave, so if you've used it and there were any
tricks, I'd appreciate some insite.

I'm using in Linux 2.4.xx.

Thanks.

the only problem I ran into was I needed to make sure the accesses to the pool were in 64 bits (two sequential 32bit ioreads), after of course resetting the device properly.  Feel free to reference talitos_rng_init() and talitos_read_random() from here:

yeah..the talitos ocf driver needs some modding to work with 2.4, sorry 'bout that.
