[ECOS] FIQ on ARM processor

[Arnaud Mouiche <arnaud dot mouiche at inventel dot fr>]

Hi.

when reading vector.s, it looks like ecos deal with FIQ like it deals with 
IRQ. Does it means there is no advantage to use FIQ than IRQ.

Has I prepare a special port, I would like to enable FIQ on this port.
There is 26 interruption sources on this processor. I choose to handle 
interruptions 0 to 25 as IRQ and to add virtual interruption from number 26 
to 51 that I will handled like FIQ.
Is it a good idea ?
If not, is there an other way to do ?

thanks
