We have talked about out of tree driver anyway
because it targets arm-arm remoteproc AMP which is not in mainline yet.
I have changed my drivers and using resource tables.
Interesting thing was that long interrupt list
is translated to resource table entry per cell and res->end is not
used to cover bigger ranges.

interrupts = < 0 29 0 0 30 0 0 31 0 0 32 0 0 33 0 0 34 0 0 35 0 0 36 0 0 52 0 0 53 0 0 54 0 0 55 0 0 56 0 0 57 0 0 58 0 0 59 0 0 37 0 0 38 0 0 39 0>;


BTW: can you please look at my microblaze email around interrupt
handlers?

Thanks,
Michal
