Hi All,
The following patches add the initial AMCC Bamboo eval board support.
The support for peripheral devices at the moment is rather limited as
the board is quite complicated in it's muxing of I/O lines. Until the
bootwrapper can figure out how to setup the EBC peripherals based on the
dip switch settings, the DTS will lack any EBC devices.
As always, comments welcome.

These three properties aren't needed (map-mask defaults
to all bits, #size is never used, #address defaults to 0
for interrupt mapping and isn't used in any other context).

You can avoid having two ranges by using #size-cells = 2
in the root node. Having two ranges is a problem if any
mapping straddles the boundary between the two.

Erm ignore this, size in a "ranges" property is encode
with the "#size-cells" of the child bus, not the parent
bus. #size-cells = 2 does fix similar problems, just
not this one :-)
> Having two ranges is a problem if any

You can get around this problem by making one range's
top or bottom boundary identical to that same boundary
of a bus range or reg range of a direct child of this
bus. Since you don't have any kids for this node yet
it doesn't matter for now, but keep it in mind.

Wasn't by accident. I was following the lead of what was done for
Ebony/440GP (which is actually broken at the moment but has a patch
pending to comment it out as above).
There is no ethernet period without the new EMAC rewrite and I'd like to
leave the select there but commented out to serve as a placeholder if
nothing else. Of course, if there are lots of objections it can be
pulled.

Ick. Can you describe roughly the setup here? It might be that the
simplest approach is to include all options in the DTS, and delete
ones that aren't selected from the bootwrapper.
I have a patch which might help here, which fills in the ebc's
'ranges' property based on the contents of the EBC bridge registers.
I'm using it as part of the code necessary to get the right address
for the Ebony flash depending on DIP switch settings.

Since a number of 4xx board firmware suffer from this EMAC/MAL reset
problem it would be nice to factor this out into a common file.

I don't think we should need this. As you suggested I added such a
clear to my UIC driver in the kernel proper.

There's 3 switches that directly control the EBC memory map, and a
handful of other pin strap registers add to that. To further complicate
things, there are two passes of the Bamboo board and the settings mean
different things to the individual board revisions.
By comparison, there's about 350 lines of code in U-Boot to do the setup
of the EBC. It's not horrible, but I'm not sure it wants to be
duplicated in the wrapper either.

Ooh... that's actually what I was thinking of doing. Though I was
planning on poking individual nodes' regs properties instead.

You may need to do both. At least if you use the same format for the
ebc binding as I have on Ebony: in the reg properties of the
individual nodes I directly encode the ebc chip select value and
offset within the peripheral bank. The ebc node's 'ranges' gives the
mappings into the OPB space. So, in practice, the low 20 bits of
address are determined by the individual peripheral's reg properties,
and the upper 12 bits are determined by the ranges property at the EBC
node.

Thanks Stephen. I can see how it would be misleading without some sort

In addition we might want a helper to fix the node unit address after
poking reg ...
