Subject: of: Fix address decoding on Bimini and js2x machines
From: Benjamin Herrenschmidt <[email protected]>
commit 6dd18e4684f3d188277bbbc27545248487472108 upstream.
Commit:
e38c0a1fbc5803cbacdaac0557c70ac8ca5152e7
of/address: Handle #address-cells > 2 specially
broke real time clock access on Bimini, js2x, and similar powerpc
machines using the "maple" platform. That code was indirectly relying
on the old (broken) behaviour of the translation for the hypertransport
to ISA bridge.
This fixes it by treating hypertransport as a PCI bus
