* [PATCH 4/10] sbc8560: Add default .config file for Wind River SBC8560
From: Paul Gortmaker @ 2008-01-24 23:41 UTC (permalink / raw)
  To: linuxppc-dev; +Cc: Paul Gortmaker
In-Reply-To: <e3ccba7097a77e66f07663fe9d1f174c06183528.1201217172.git.paul.gortmaker@windriver.com>

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.

* [PATCH 5/10] sbc8548: Add basic support for Wind River SBC8548 as powerpc
From: Paul Gortmaker @ 2008-01-24 23:41 UTC (permalink / raw)
  To: linuxppc-dev; +Cc: Paul Gortmaker
In-Reply-To: <e3ccba7097a77e66f07663fe9d1f174c06183528.1201217172.git.paul.gortmaker@windriver.com>

This adds the basic support for the Wind River SBC8548 board, implemented
as powerpc.  It closely follows the implementation of the MPC8548CDS.

* [PATCH 3/10] CPM2: Make support for the CPM2 optional on 8560 based boards
From: Paul Gortmaker @ 2008-01-24 23:41 UTC (permalink / raw)
  To: linuxppc-dev; +Cc: Paul Gortmaker
In-Reply-To: <e3ccba7097a77e66f07663fe9d1f174c06183528.1201217172.git.paul.gortmaker@windriver.com>

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 2/10] sbc8560: Add v1 device tree source for Wind River SBC8560 board
From: Paul Gortmaker @ 2008-01-24 23:41 UTC (permalink / raw)
  To: linuxppc-dev; +Cc: Paul Gortmaker
In-Reply-To: <e3ccba7097a77e66f07663fe9d1f174c06183528.1201217172.git.paul.gortmaker@windriver.com>

This adds a v1 device tree source for the Wind River SBC8560 board.  The
biggest difference between this and the MPC8560ADS reference platform
dts is the use of an external 16550 compatible UART instead of the CPM2.

* [PATCH 1/10] sbc8560: add support for Wind River SBC8560 in arch/powerpc
From: Paul Gortmaker @ 2008-01-24 23:41 UTC (permalink / raw)
  To: linuxppc-dev; +Cc: Paul Gortmaker
In-Reply-To: <12012180922447-git-send-email-paul.gortmaker@windriver.com>

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

* [PATCH 0/10] Support for SBC834x/8548/8560 Wind River Boards
From: Paul Gortmaker @ 2008-01-24 23:41 UTC (permalink / raw)
  To: linuxppc-dev


This series contains the patches for the Wind River SBC834x, SBC8548 and
SBC8560, grouped together for merge convenience.

Changes since previous:

sbc834x:
	- machine_device_initcall as per Kumar's recent commit 6392f184
	- remove four device_type from dts that DavidG wanted gone.
	- add of_node_put() and __initdata as per StephenR's suggestions.

sbc8548:
	- fold the dts, and conversion to dts-v1, into a single commit

sbc8560:
	- dts has localbus with 2 address cells (chipsel) and epld as child
	- UART detection legacy_serial patch separated out from 8560 patches
	- fold the dts, and conversion to dts-v1, into a single commit

I've boot tested these all on "for-2.6.25" to make sure things are sane.
Thanks again to those who have suggested improvements and changes.

Paul.

Are you adding padding to your dtb?

Try adding "-p 1024" to your dtc command line

The driver being patched is used in both the powerpc and ppc builds.

* [PATCH] [POWERPC] Add a cuboot wrapper for 85xx w/CPM2
From: Kumar Gala @ 2008-01-24 22:44 UTC (permalink / raw)
  To: linuxppc-dev

The bd info struct changes if we have CPM2 enabled in u-boot.

Oops, that should have been __initdata to be 100% correct...

Subject: [PATCH] powerpc: reduce code duplication in legacy_serial, add UART parent types

The legacy_serial was treating each UART parent in a separate code block.
Rather than continue this trend for the new parent IDs, this condenses
all (soc, tsi, opb, plus two more new types) into one of_device_id array.
The new types are wrs,epld-localbus for the Wind River sbc8560, and a
more generic "simple-bus" as requested by Scott Wood.

 == 0 should work on powerpc since NO_IRQ is defined to be 0 there no ?

Anyway, using the symbolic constant is always nicer I suppose.

I do not know why it is creating two chosen node. In my dts file I have
placed one empty chosen node:=20
chosen{
	};
If I do not do this,  I get the following error during boot process:

libfdt: FDT_ERR_TRUNCATED
Failed creating the /chosen node (0x00C00000), aborting.

Any reason??

Ben, do you approve of this? How should error be checked for, is
<NO_IRQ right? The current code in the kernel looks to be broken
because of these checks, the ppc build is wrong and powerpc polled
mode doesn't work.

you can't have two chosen nodes. Linux renames the second one to chosen#1 and thus can't find the kernel arguments.

Hi All,
Our custom board is leveraged from MPC8541cds from freescale.
We have been running Linux 2.6.11 on it recently I have tried to boot
the system with the latest Linux 2.6.22-rc4 from PowerPC git tree.
 
I did ported the libfdt to our older version of the uboot and were able
to
resolve the device tree. After downloading the uImage, dtb file and
ramdisk
I use the bootm command to boot the linux, but it failes..
........................................................................
...................
driver initialized: 16 RAM disks of 4096K size 1024 blocksize
VFS: Cannot open root device "<NULL>" or unknown-block(0,0) Please
append a correct "root=" boot option; here are the available partitions:
Kernel panic - not syncing: VFS: Unable to mount root fs on
unknown-block(0,0) Rebooting in 180 seconds..
........................................................................
...............
 
During boot I observeed that the "kernel Command Line:" is empty, is
this parameter should be supplied by fdt also?
 
I have copied the boot log and dump of the device tree below, Any help
greatly appreicate it.
 
Thanks,

Sorry, I don't know what I was thinking - of course you don't need it.

When the board designer decides to hook eth0 up to UCC5.

If the board designer decides to hook multiple devices up to UCC5, we first
smack the board designer, and then set it up to whichever configuration has
been jumpered.

Also add "simple-bus" to the CPM node.

No.  I'd have to closely examine the DTS, but I don't think that UCC devices 
share pins at all.  But that isn't my point.

Yes, but deciding what the UCC does might not be static.  At what point do we 
declare, "UCC5 is for eth0 and eth0 only"?

The advantage of putting the pin configurations in the device tree is that they 
now become configurable.  I can envision a scenario where UCC5 could be either 
an Ethernet or a UART, depending on the setting of some jumpers on the board. 
That's what the QE was designed for: any UCC can do any task, and you can even 
have a UCC change its purpose while the system is running.  So I don't want the 
pin configurations hard-coded into the kernel.  Having them in the device tree 
gives me some flexibility.

For instance, I have a plan (that I keep postponing) to introduce a new feature 
in U-Boot where U-Boot can determine the settings of some board jumpers and 
modify the device tree accordingly.  The instructions on how to modify the 
device tree would be embedded in the tree itself.  I can't support this feature 
if the kernel calls par_io_config_pin() regardless of what's in the device tree.

If hardware configuration is selected at the bootup time, by jumpers
or switches, it's even easier to do it right. Without pio-map.

Why you need to modify the device tree for that? Let the U-Boot simply
setup pins for the kernel. Regarding kernel overwriting pins
configuration...

What I've understood from the previous debates, is that ideally kernel
should not touch pins' configuration. Today we're using pio-map solely
to fix up some old firmware misconfiguration. And we can do this in the
board file still. To determine if we need to fixup the firmware or not,
we can use some device tree property instead (firmware version?).

p.s.
I'm neither for pio-map nor against. I just want some consequence
regarding this. Last thread ended with consequence that pio-map is a
bad thing to use...

Are you saying that TDM is sharing same pins with the other QE device,
and we can choose to use/not use some device depending on which driver
is loaded? I think this particular board and patch isn't that case.

Even if someday there will be the case when drivers are mutually
exclusive, i.e. presence of some driver should trigger pins
reconfiguration, then anyway this should be handled differently.

That is, we should not _register_ two mutually exclusive devices
in the first place, so drivers will not probe them. That's board
setup code authority, and pins configuration still should happen
there.

[ Irrelevant to UCCs and this particular case: lately I've
  encountered one interesting case of Par IO usage. FHCI USB needs
  switching between pin's dedicated functions and GPIO functions.
  So, firstly it is using pins as dedicated, and later (at the bus
  reset) driver turns them to act as GPIOs. This is still handled
  without pio-map though, via gpios = <> property for that driver. ]

In that particular case UCC configuration is static, for every UCC.
So, we can set up all pins in the firmware/board file.

Please correct me if I'm wrong.
