[PATCH 1/4] powerpc: mv64x60 - Use early_* PCI accessors for hotswap reg

[Mark A. Greer]

From: Mark A. Greer <mgreer@mvista.com>

The mv64x60 Hotswap register is on the first hose of the mv64x60
hostbridge.  To access it, manually find the hose structure and
use the early_* PCI accessor routines because the hostbridge is
normally hidden.

You seem to have virtual-reg properties on a *lot* of nodes, are they
really necessary?  virtual-reg should be used *only* for things which
you need to access very early in the bootwrapper.  Usually that's only
the serial port for the console.  Come to that, the CPU is a 750 which
has a real mode, so it seems dubious that you would need any
virtual-reg values at all.

If you're using the "label" property, it would be normal to name the

Two PCI bridges with identical bus-range values seems potentially

The dts file should not include a "bootargs" value.  The wrapper will

Its used in the bootwrapper if & when you use the mv64x60 code to setup
some of the windows to the I/O ctlrs.  This port does use that code
(because firmware doesn't do it properly) so I need the flag.

Actually, not all of them for this board.  I copied them from prpmc2800
which does need all the ones that are there.  I'l remove the ones that
aren't used.

Well, this came from a discussion about a year ago when we agreed that
this is how it should be done.  Just because MSR[IR,DR] can be cleared
doesn't mean that they are cleared when the firmware jumps to the
bootwraper (for all possible firmwares that are out there).

To be able to eliminate virtual-reg, we'd have to add "mmu_off" code to
the bootwrapper which isn't hard but its already in the kernel (for
32-bit anyway).  So why duplicate?

I'm not that attached to virtual-reg.  In fact, I'd be happy to get rid
of it but only if we can be sure it doesn't cause more mess down the
road.

I'm using the partition names that were used in the equivalent code
under arch/ppc.  I'm trying to keep things looking the same as they used
to as much as possible.  Besides, I don't see any others doing it that
way.

Does it?  Its a separate block of regs but its only used in the mpsc
node--its never looked up on its own by kernel code.  Do all nodes need
"compatible" even when it'll never be used?  (Just want to know.)

mpp == multi-purpose pins
gpp == general purpose pins

They're really 2 separate reg blocks and are used for any number of
things including incoming PCI interrupts.  I'm not accessing them
currently so I can eliminate them in this dts.

Actually, the kernel .config CONFIG_CMDLINE is only used by the kernel
when nothing is passed in from the bootwrapper.  The bootwrapper gets
the cmdline from either bootargs or from the __builtin_cmdline section.

I prefer to not rely on CONFIG_CMDLINE because it doesn't afford the
user a chance to edit or add to the cmdline when booting.  You can always
type in the whole thing at the "Linux/PowerPC load: " prompt but I'd rather
see what is going to be used and then edit it if I want to.  With
CONFIG_CMDLINE, it just gets used if nothing was passed in from the
bootwrapper.

That raises an issue that I've for time time (I've tried to get rid of
__builtin_cmdline before but was unsuccessful).

We currently have 3 possible sources for a default cmdline--seems like
at least one too many.

IMHO we need a way to change the default cmdline in the field so
sysadmins can change it per board and not have to type it in every time
they boot.  /chosen/bootargs and __builtin_cmdline can both do that.
We don't need both, though.  And, since bootargs is specified by OF
and documented in booting-without-of.txt, can we finally get rid of
__builtin_cmdline?  I'd sure like to.

We can probably get rid of CONFIG_CMDLINE too since everyone uses DTs
now and they can have a /chosen/bootargs.  Anyone have a reason to keep
CONFIG_CMDLINE around?

Would you mind elaborating on why you are opposed to /chosen/bootargs?

Hrm.. ok.  I'm just wondering if a new flag is really the right
approach for this, or whether you should be basing the setup off the
compatible property, either for the board or for the main bridge.

My point is that the partition code uses either "label" (if present)
or the node name for the partition name.  If label properties are
present, the node name is redundant information, so it seems more
sensible to leave something generic there.

Hrm.. if it's really just extra mpsc registers, should it be a
seperate device, or just another range in the mpsc's "reg" property?

Hrm.  The device tree should generally describe the hardware, even if
Linux doesn't use it yet.  Are these basically some sort of GPIO
interface?  If so you should look at the new GPIO binding which has
been proposed.

Yes :(.  I've looked at this before, though obviously I never got to

I'd prefer to keep the flag.  Otherwise, the bootwrapper will need a
table to look up the compatible field to see if coherency is supposed
to be on or off.  We'd have to add an entry to that table for any
compatible that need coherency off, etc.  A flag seems cleaner.

Ah, okay.  I'll do:
	partition@0 {
		label = "Monitor";
		reg = <0x00000000 0x00100000>;
	}
	partition@100000 {
		label = "Primary Kernel";
		reg = <0x00100000 0x00180000>;
	}
	...

Okay, putting into the reg property makes sense.  Its values will be
put into both mpsc@xxx 'reg' properties since its share.  That doesn't
matter, correct? 

Also, would you mind letting it go thru as it is now and I'll make a
separate patch to change this dts, the prpmc2800.dts, and related code
afterwards?

I should take the time to read up on that but neither of these are used
by the katana so I'll get rid of them for now.  I can always put them
back.

Yeah, but changing CONFIG_CMDLINE requires a kernel rebuild so
that's not great either.  Modifying __builtin_cmdline is probably the
easiest way to change things in the field (assuming you have a zImage)
but its also the least standard way of the three. :(

Hrm.  Except that you already have such a table in the cuboot file,
adding another flag to that wouldn't be hard.

What piece of hardware is it that actually determines whether
coherency works or not?  The CPU?  The bridge?

Ah, sorry, I forgot there were multiple mpscs.  Their reg properties
certainly shouldn't overlap, so you will need a separate node.
However, you could combine your several nodes with MPSC common
registers into a single "mpsc-common" (or something) block.  That
would also reduce the number of phandles you need in the mpsc nodes,
too.

Or possibly this should be arranged as for the multiethernet.

Well, that's not really up to me.

But since the device tree is built into the zImage, changing it there
will also require a rebuild.  No difference from that PoV.  I'd really
suggest leaving this with CONFIG_CMDLINE just for similarity to other
platforms until we figure out how to clean up the commandline
confusion more generally.

The bridge + the platform.  There's a hw erratum that some boards have
worked around and other haven't.

Spoze I can just code it in the cuboot file as you say.
I'll have to remove the sanity check in the kernel that ensures
that coherency-off & CONFIG_NOT_COHERENT_CACHE match.

True, that will help.

Do you mean putting sdma/brg/... as subnodes of the mpsc node?
I remember debating this way back when.  IIRC, leaving them out seemed
like the right thing to do (tm).  If you think that's better, I can do
that.

Yeah, but paulus is looing to you to monitor bootwrapper stuff so... :)

Nope, you can run the wrapper script to change it without rebuilding the
kernel.  You just need the dts file and a working dtc (and the wrapper
script).  Goes back to paulus' original intent with the wrapper script.

[PATCH 3/4 v2] powerpc: Katana750i - Add DTS file

[Mark A. Greer]

From: Mark A. Greer <mgreer@mvista.com>

Add DTS file for the Emerson Katana 750i & 752i platforms.

Signed-off-by: Mark A. Greer <mgreer@mvista.com>
---
This patch should address most of David's comments.

Some notes:
- Even though there are still several virtual-reg's remaining, all
  are used by the bootwrapper.
- I'll make a separate patch to get rid fo the cunit & mpscrouting nodes.
- I left /chosen/bootargs since its nice to have the default cmdline
  printed by the bootwrapper and then have the opportunity to edit it.

Maybe there should be a stub of mv64x60_pci_init for the non PCI case -
that would save the ifdefs in C code.

What if np == NULL?

[PATCH 4/4 v2] powerpc: Katana750i - Add platform support

[Mark A. Greer]

From: Mark A. Greer <mgreer@mvista.com>

Add support for the Emerson Katana 750i & 752i platforms.

Signed-off-by: Mark A. Greer <mgreer@mvista.com>

This patch should address all of Stephen's comments.
I also did some cleanup that I missed the first time through.

You need an of_node_put(np) for the !reg case above.  Maybe you should
just put it after the else clause instead of in it.

This enum appears to be pointless.  You never use it as a type, and
there's no reason to explicitly give array indices for the
board_info[] array.

I would think that this is way to big to inline ...

Yeah, I suppose.  I'm not sure why I made it an inline, TBH.  I'll make
it a "real" routine.

[PATCH 1/4 v2] powerpc: mv64x60 - Use early_* PCI accessors for hotswap reg

[Mark A. Greer]

From: Mark A. Greer <mgreer@mvista.com>

The mv64x60 Hotswap register is on the first hose of the mv64x60
hostbridge.  To access it, manually find the hose structure and
use the early_* PCI accessor routines because the hostbridge is
normally hidden.

Can't we unhide the NB instead ?

Hi Ben.

Possibly but it may cause issues since many hostbridge have BARs
that don't comply with the PCI spec which may get hosed when scanning
the PCI bus.  Maybe fixups/quirks/whatever will help but I'm not sure
that's any cleaner.  TBH, I'm not familiar enough with the PCI subsystem
to answer this intelligently.

True. But it's nice to be able to see their config space.

I tend to use a header quirk to blank the BARs of the host bridge in
those cases. But that does mean that the sizing operation is done on
them (writing ff's etc...) which might be an issue in your case (or
not).

Ben.
