7a8b64d17e35810dc3176fe61208b45c15d25402 is the first bad commit
commit 7a8b64d17e35810dc3176fe61208b45c15d25402
Author: Rob Herring <r...@kernel.org>

of/address: use range parser for of_dma_get_range
on what appears to have been a DT system with a built in DT from
the firmware, using upstream's defconfig. I dimly recall seeing
some discussion of issues here in the past, though I don't have
one of these boxes myself so wasn't paying huge attention. I'd
guess there's some bug in the DT which given that this is in the
firmware the kernel ought to fix up during early init, if someone
with better access to one of these systems could supply a DT for
inspection that might help people figure things out.
I suspect the machines might work fine when booted with ACPI
firmware.
