[PATCH 0/4] arch/powerpc support for SBC8560 board

[Paul Gortmaker]

The following four patches add support for the Wind River SBC8560 board
onto the powerpc branch.  The patches are as follows:

1) Add basic support for Wind River SBC8560 as powerpc

This adds in the basic platform support file -- closely matching that which
exists for the MPC8560ADS board.

 b/arch/powerpc/platforms/85xx/Kconfig   |   11 -
 b/arch/powerpc/platforms/85xx/Makefile  |    1 
 b/arch/powerpc/platforms/85xx/sbc8560.c |  303 +++++++++++++++++++++++++++++++-


2) Make support for the CPM2 optional on 8560 based boards

Since the SBC8560 has a 16550 compatible UART on board, there really is
no direct requirement for any of the CPM functionality to be forced on
all the time.  This allows you to turn off the CPM2 support for this board.

 b/arch/powerpc/platforms/85xx/Kconfig |    4 ++--
 b/arch/powerpc/platforms/Kconfig      |    5 ++---


3) Add device tree source for Wind River SBC8560 board

This is probably the most interesting part of the group, given that the
board doesn't use the CPM2 to provide the serial console.  I've made a
duart dts entry that is kind of similar to what is done for the tsi108
on the mpc7448/hpc-ii board, and made sure that the serial had their
parent marked as "soc" (found out the hard way that UARTs were ignored
as possible consoles unless they were soc or tsi108 children...)

 b/arch/powerpc/boot/dts/sbc8560.dts |  203 +++++++++++++++++++++++++++++++++++-


4) Add default .config file for Wind River SBC8560

 b/arch/powerpc/configs/sbc8560_defconfig |  765 ++++++++++++++++++++++++++++++-

This config gives basic serial console and ethernet support for doing an
NFS root setup.  The SBC8560 can be used as a PCI host when put into
a suitable backplane, and the FCC ports can be used for eth2/eth3 if
the board is fitted with a daughtercard with a couple Broadcom PHY, but
at the moment these features aren't enabled/tested as they weren't on
the board I was using.


I'd quickly spun together a u-boot 1.2.0 for testing this -- since that was
the quickest route to getting a powerpc capable version.  I'll see what
can be done for getting a u-boot 1.3.1 patchset out so the local-mac-address
vs address thing in the dtb isn't an issue.

Paul.

[PATCH 1/4] sbc8560: add basic support for Wind River SBC8560 as powerpc

[Paul Gortmaker]

This adds the basic support for the Wind River SBC8560 board, implemented
as powerpc.  It closely follows the implementation of the MPC8560ADS.

[PATCH 2/4] CPM2: Make support for the CPM2 optional on 8560 based boards

[Paul Gortmaker]

Currently there is no way to disable the CPM2 support.  Some boards,
like the SBC8560 have their own external UART and don't have any direct
dependencies on the CPM for a serial console or anything else.

[PATCH 3/4] sbc8560: Add device tree source for Wind River SBC8560 board

[Paul Gortmaker]

This adds the device tree source for the Wind River SBC8560 board.  The
biggest difference between this and the MPC8560ADS reference platform
is the use of an external 16550 compatible UART instead of the CPM2.

[PATCH 4/4] sbc8560: Add default .config file for Wind River SBC8560

[Paul Gortmaker]

This is a suitable .config file for building the WRS SBC8560 kernel
to be used for NFS root via one of the TSEC interfaces and with
serial console via the 16550 compatible UART on the board.

We often say "if (!np)" and leave out the blank line above.

Need an of_node_pit(np) - cpm2_pic_init() does its own of_node_get.

do you really need to exclude the PHB itself?  I've fixed this for FSL  
PHBs so I don't believe you need this anymore.

we need to figure out to fix this so we don't need the parent marked  
as 'soc'.

Out of interest how exactly are the duart's wired on the 8560.  Are  
they off localbus?

Probably should add a boot wrapper to work with old non-device tree

Drop the "32-bit".  It was created in analogy with the "64-bit"
property, but nothing ever actually specified it.

I believe we're trying to call these "soc@address" now rather than
"socXXXX@address".

This should be "clock-frequency" not "bus-frequency" although I don't
know if you can fix this within your code, or if it's a pre-existing
brokenness.

And this one, and change the compatible.  The gianfar driver has

This is neither an interrupt-controller nor an interrupt-nexus, so it
shouldn't have #interrupt-cells.

!?  If console checks this (whatever that means), then console is
doing crap...

This is clearly *not* a SoC, and should have a proper compatible, not
this crap device type.  Come to that, is this really an independent
device or does it belong within the soc or on the localbus or
something?

Ranges and reg should not overlap like this, except in very unusal
cases.  I'm really not sure what this duart node is support to
represent, in any case.

No leading zeroes on the unit address part of the name

Again, it looks very much like the duart and rtc belong off some
external bus controller, not directly on the CPU bus (which is what
the top-level of the device tree represents).

This has no child nodes, so no need for #address-cells and #size-cells.

Drop device_type, we're trying to avoid them.

Here is my interpretation of what is happening here -- we come in via
find_legacy_serial_ports() to pick a console port.  It grabs "chosen"
to get np stdout, and then checks the parent of the 16550 compat ports
against the following, requiring at least one of them to match:

	parent->type == "soc" ? add_legacy_soc_port()

	parent->type == "isa" ? add_legacy_isa_port()

	parent->type == "tsi-bridge" ? add_legacy_soc_port()

	parent->type == "opb" ? add_legacy_soc_port()

No match means no serial console, it seems.  I figured that parent == "soc"
was the lesser lie to choose from, but I'm open to an alternate approach 
that is less apt to make David go "ewww" (an understandable reaction...).

The board has a bunch of stuff hanging off of CS5 -- an RTC, a 7 segment
display, an EEPROM, some BCSR-like registers, and of course the two
UARTs which are supposed to be 16C2550.  According to TFM, an EPM7128
PLD is responsible for mashing/sub-decoding this all onto/off of CS5.
CS3 and CS4 are the LB-SDRAM.

Something to consider, sure -- but I figured working towards a more up
to date u-boot is something people would see more of a future for and
more of an interest in.

Not necessarily.  If the port is picked up by the of_serial driver it
should work.  The drawback is that the console will be initialized
rather late by this method.

Lying in the device tree like this is just bad.  Adding another case
to legacy_serial for your specific case would be ugly but infinitely
preferable to mislabelling the node with type "doc".

Sounds reasonable to me.  I've integrated these into sbc8560.c (still
looking at how to handle the duart/dts based on feedback).  Since I'd
inerited the things you'd requested fixes on from mpc85xx_ads.c, it
probably makes sense to fix them there too I would imagine.  I'll send
that under its own subject in a minute.

We should probably add a parent-is-compatible-with-"simple-bus" check, to
avoid needing to extend this hack even further.

I'd put these devices under a /localbus node.

Yes, there's a timer on the PIC.

This is debatable. :-)
