This patch is word wrapped. Seems your mailer decided to eat tabs as

Actually, the patch just adds a backend to my little framework for
dealing with 4xx PCIe, which basically is a boring piece of code
filling registers with values mostly from the spec... nothing really
fancy there.

* [PATCH v2 1/5] [POWERPC] Add AMCC 460EX/460GT support to cputable.c & cpu_setup_44x.S
From: Stefan Roese @ 2008-02-23 21:07 UTC (permalink / raw)
To: linuxppc-dev
This patch adds basic support for the AMCC 460EX/460GT PPC's to arch/powerpc.
Currently those PPC's are still based on a 440 core and *not* a 460 core.
Here some basic features of those SoC's:
460EX:
- Up to 1.2GHz, 32kB L1 I-cache and D-cache, 256kB L2-cache, FPU
- 1 * PCI (max 66MHz), 2 * PCIe (one 4-lane, one 1-lane)
- 2 * GBit Ethernet with TCP/IP acceleration
- USB 2.0 Host/Device OTG and Host interface
- SATA controller
- Optional security feature
460GT (only changes to 460EX):
- 4 * GBit Ethernet with TCP/IP acceleration
- RapidIO
- No SATA
- No USB

* [PATCH v2 2/5] [POWERPC] Add AMCC Canyonlands 460EX eval board support to platforms/44x
From: Stefan Roese @ 2008-02-23 21:07 UTC (permalink / raw)
To: linuxppc-dev
Canyonlands is the AMCC 460EX eval board, featuring nearly all of the 460EX
interfaces:
- 1 * PCI (max 66MHz), 2 * PCIe (one 4-lane, one 1-lane)
- 2 * GBit Ethernet with TCP/IP acceleration
- USB 2.0 Host/Device OTG and Host interface
- SATA port

* [PATCH v2 5/5] [POWERPC] Add 460EX PCIe support to 4xx pci driver
From: Stefan Roese @ 2008-02-23 21:08 UTC (permalink / raw)
To: linuxppc-dev
All this code is needed to properly initialize the 460EX PCIe host
bridge(s). We re-initialize all ports again, even though this has been done
in the bootloader (U-Boot) before. This way we make sure, that we always
run the latest init code in Linux and don't depend on code versions from
U-Boot.
Unfortunately all IBM/AMCC chips currently supported in this PCIe driver need
a different reset-/init-sequence.
Tested on AMCC Canyonlands eval board.

Sounds like Jean isn't very excited about this idea..

I have to say no on this one. The device tree is not supposed to know
about how linux uses devices, there are firmwares out there that don't
use DTS for thier device trees, etc.
> 3. use a glue layer with a translation map.
In my opinion this is an OK solution since the same information has to
be added somewhere already anyway -- eiither to the drivers or to this
translation table. It should of course be an abstacted shared table,
preferrably contained under the i2c source directories since several
platforms and architectures might share them.

* [PATCH 1/2][OF] Add of_device_is_disabled function
From: Josh Boyer @ 2008-02-23 21:58 UTC (permalink / raw)
To: sfr, davem; +Cc: linuxppc-dev
IEEE 1275 defined a standard "status" property to indicate the operational
status of a device. The property has four possible values: okay, disabled,
fail, fail-xxx. The absence of this property means the operational status
of the device is unknown or okay.
This adds a function called of_device_is_disabled that checks to see if a
node has the status property set to "disabled". This can be quite useful
for devices that may be present but disabled due to pin sharing, etc.

In-Reply-To: <20080223155823.2c85d829@zod.rchland.ibm.com>
Some SoC chips have multiple serial ports on board. The usability of these
ports can rely on various factors, ranging from pin sharing to unpopulated
connectors. This uses the new of_device_is_disabled function to check for
and ignore disabled UARTs.

* [PATCH 0/3] [POWERPC] 4xx: Add support for AMCC 440EP Yosemite board
From: Josh Boyer @ 2008-02-23 22:08 UTC (permalink / raw)
To: linuxppc-dev
This small series of patches adds support for the AMCC 440EP Yosemite
evaluation board. This is the newer evaluation board for PowerPC 440EP
chips, replacing the older Bamboo board.
This is just the initial round of patches, but they are functional.
Also of note is that while all for on-board UARTs are enumerated in the
DTS file, only two of them are usable on the board. The other two have
their "status" property set to disabled. If used in conjunction with
the of_device_is_disabled patches I just sent out, then devices for
those won't be created. This is not required.

* [PATCH 2/3][POWERPC] 4xx: Add platform support for the AMCC Yosemite board
From: Josh Boyer @ 2008-02-23 22:09 UTC (permalink / raw)
Cc: linuxppc-dev
In-Reply-To: <20080223160813.2f8d282b@zod.rchland.ibm.com>
The AMCC 440EP Yosemite board is very similar to the original AMCC Bamboo
board. This adds a YOSEMITE option to Kconfig, and reuses the existing
bamboo board support in the kernel.

Olof asked on IRC why even bother enumerating the extra UARTs. I have
two reasons for this.
1) I want a user of the of_device_is_disabled patches, if only to show
it works and provide an example (it does work btw).
2) When I get to doing the EBC stuff for bamboo and yosemite, there are
devices that can come and go depending on dip switch settings (due to
pin sharing). My nefarious plan is to enumerate all of the devices in
the device tree, and poke a status = "disabled" property into the ones
that are no longer usable because of the dip switch settings. E.g.
EMAC1 becomes disabled if the NAND flash is enabled on Bamboo, etc.

Talking with Ben H a bit, he suggested to reverse this API. Basically,
create an of_device_is_available that returns 1 if the status property
is completely missing, or if it's set to "okay" or "ok". The latter is
to cope with some broken firmwares.
I can do either really. Eventually you could embed the is_available
check in the of_platform code so that devices don't even get presented
to drivers if they aren't available.
Dave, I'm not sure how applicable this all is to sparc. But for some
of the "newer" embedded ports that are coming into powerpc I can see it
being very useful.
Thoughts?

And since I seem to be talking to myself and have nothing better to do
on a Saturday evening, here's the code.
josh
IEEE 1275 defined a standard "status" property to indicate the operational
status of a device. The property has four possible values: okay, disabled,
fail, fail-xxx. The absence of this property means the operational status
of the device is unknown or okay.
This adds a function called of_device_is_available that checks the state
of the status property of a device. If the property is absent or set to
either "okay" or "ok", it returns 1. Otherwise it returns 0.

* [PATCH] [POWERPC] mpc5200: fix build error on mpc52xx_psc_spi device driver
From: Grant Likely @ 2008-02-24 5:49 UTC (permalink / raw)
To: dbrownell, dragos.carp, linux-kernel, linuxppc-dev,
spi-devel-general
From: Grant Likely <grant.likely@secretlab.ca>
Commit id 94f389485e27641348c1951ab8d65157122a8939 (Separate MPC52xx PSC
FIOF regsiters from the rest of PSC) split the PSC fifo registers away
from the core PSC regs. Doing so broke the mpc52xx_psc_spi driver.
This patch teaches the mpc52xx_psc_spi driver about the new PSC fifo
register definitions.

This is a build error bug fix which needs to go into .25

This is the only function that is still in camel case; it should
probably be changed also... In fact, this functions doesn't seem to be
used at all. Can it just be removed? Are there any other unused
functions in this driver?

This looks like it should be 'char __user *buf' instead of '__user char *buf'.

Why not mutex_lock_interruptible()? (goes for all cases of mutex_lock())

Stephen, when you address these comments, please double check the lkml
address. It was misspelled when you sent this patch.
Cheers,

I'm OK with the syntax, but whatever-ish.
Would these be better?:
prop = /call/(incbin, "path/to/data", 17, 23);
prop = /call[incbin]/("path/to/data");
prop = /call incbin/("path/to/data", 12, 12+10);
What is the aspect of the syntax that you don't like?
I think we essentially need to stick in the /.../ realm
to be consistent with the other non-standard names being
used, like /include/.
I can see a generalized form that allows other pre-defined
or user-defined "functions" to be introduced and called
or used in a similar way:
prop = <(22 + /fibonacci/(7)) 1000>;
prop = /directoryof/("/path/to/some/file.doc");
interrupt-map = /pci_int_map/(8000, 2, 14);
or whatever. We can paint this bikeshed for a long time
if we need to. Or, we can get down to some serious issue
if there are any. Are there?
