In the DTB tree created by firmware on some Maple 64bit targets,
such as ATCA6101,
these two properties, address&size, should be 2.
And they are.
But the actual corresponding values
of host bridge node are set 1 incorrectly by the firmware, we have
to provide one
fixup function to fix that.
It is the "reg" property that is incorrectly encoded as-if
#address-cells and #size-cells were 1.
Please fix the commit message (and subject line).
+ name = "/hostbri...@f8000000";
+ hb = call_prom("finddevice", 1, 1, ADDR(name));
It's interesting that the firmware can find your node this way,
it won't match the "reg"! Looks like there is more than one
bug in there.
Code looks good,
