Hello,
There is an issue with the identification of ATA drives with our
P.A. Semi Nemo boards [1] after the
commit "of/irq: Factor out parsing of interrupt-map parent
phandle+args from of_irq_parse_raw()" [2].

My earlier request for valuable debug information still stands. But
while you're at it, can you please give the following hack a go?

This may not be the final workaround even if it solves your boot
problem, but will at least give us a hint at what is going wrong.
I have the fuzzy feeling that we may be able to lob this broken system
as part of the of_irq_imap_abusers[] array, which would solve things
pretty "neatly".

We tested this patch yesterday and it solves the boot problem.
Thanks
