There are at least two other ways that you might be able to reset a
board:
1) Internally through the ICAP device.
2) Through a GPIO connected externally to the reset logic.

If the problem is in the device trees that are being generated, we
should fix the issue there.
We've been trying to avoid putting the fully specified IP versions in
the kernel like this, since
the IP changes so often.

I think the mainline driver might (still) assume the presence of a PLB->DCR
bridge?
So there are really 4 cases:
Core has DCR access, accessed directly using DCR.
Core has DCR access, accessed indirectly using DCR.
Core has DCR access, accessed through plb->dcr bridge.
Core has PLB access.

It seems to me like what's confused in the defconfigs is two concepts:

The first could allow you to drop 99% of the options (I think t

Mainly, this involves two changes:
1) xilinx->xlnx (recognized standard is to use the stock ticker)
2) In order to have the device tree focus on describing what the
hardware is as exactly as possible, the compatible strings contain the

These patches synchronize all the in-kernel drivers to use the
compatible names generated by the UBoot BSP generator.
(at git://git.xilinx.com/gen-mhs-devtree.git)
The patches to make this work are coming shortly:
patches 1-2 are provided for context only... They're not ready for
mainline. They

This target produces a flat binary rather than an ELF file,
fixes the entry point at the beginning of the image, and takes
a complete device tree with no fixups needed.
The device tree must have labels on /#address-cells, the timebase
frequency, and the memo
o needs to
get pulled to powerpc.

Includes both flavors of plb, opb, dcr, and a pseudo 'compound' bus
for representing compound peripherals containing more than one logical
device.

Mainly, this involves two changes:
1) xilinx->xlnx (recognized standard is to use the stock ticker)
2) In order to have the device tree focus on describing what the hardware is as
exactly as possible, the compatible strings contain the full IP name and IP
version.

This now better describes what the UBoot device tree generator actually does.
In particular:
1) Nodes have a label derived from the device name, and a node name
derived from the device type.
2) Usage of compound nodes (representing more than one device in the same IP)
which actually works. Thi

Thanks, I've updated the generator to reflect this.
