It seems reasonable if you had a FPGA off of the localbus to have a
two level representation. One for the localbus controller on the FSL
part and the child to describe the FPGA.
What are you expecting beyond what we have today? I guess I'm asking
what's missing from the localbus nodes we have?

* [PATCH] ehea: fix sysfs link compile problem
From: Jan-Bernd Themann @ 2008-02-01 14:37 UTC (permalink / raw)
To: Jeff Garzik
Cc: Thomas Klein, Jan-Bernd Themann, netdev, linux-kernel, linux-ppc,
Christoph Raisch, Marcus Eder, Stefan Roscher
Due to changes in the struct device_driver there is no direct
access to its kobj any longer. The kobj was used to create
sysfs links between eHEA ethernet devices and the driver.
This patch removes the affected sysfs links to resolve
the build problems.

Hey Grant!
Here's how dumb I am: You were thinking "Something's wrong here..."
and kept saying "Needs a model name!", and I kept saying "That _is_
the model name!" And finally Dave comes along and with the ever-obvious
"Needs a vendor prefix!"
I'm like, "D'oh!"

Ah, good point. I'll get around to an update patch!

* PCI configuration with multiple PCI controllers
From: Laurent Lagrange @ 2008-02-01 14:33 UTC (permalink / raw)
To: linuxppc-dev
Hello,
I have a MPC8641 based board. I try to use the two PCIe controllers. My
firmware configures (physically) the PCI buses as follow:
------------------+
MPC8641 PCIe 1 | bus 1 +--------------+
| --------------> | PCI device 0 |
BUS 0 | +--------------+
- - - - - - - - - +
MPC8641 PCIe 2 | bus 3 +--------------+
| --------------> | PCI device 1 |
BUS 2 | +--------------+
------------------+
I launch the Linux image (2.6.23.9). During the Kernel PCI configuration,
buses behind the 2nd MPC8641 PCIe are skipped because its primary bus don't
start at bus number 0. The kernel reconfigure the primary bus number of the
MPC8641 PCIe 2 controller from 2 to 0.
I can patch the kernel to work with my firmware but I don't know if my PCI
configuration is the good one.
What is the common way to configure the PCI for Linux when a new controller
is found: start the bus number to 0 or to the last bus number + 1?
Regards
Laurent

The file as to be all one format or the other, it can not be mixed.
Kumar applied my patches to convert all the 86xx FSL boards to /dts-v1/
and they have gone into Paul's and Linus' mainline already.
If another old style node goes by, we should all gang up on it! :-)

* [PATCH v4] [POWERPC] MPC8360E-RDK: device tree, board file and defconfig
From: Anton Vorontsov @ 2008-02-01 13:56 UTC (permalink / raw)
To: Kumar Gala; +Cc: linuxppc-dev
This is new board made by Freescale Semiconductor Inc. and
Logic Product Development.
Currently supported:
1. UEC{1,2,7,4};
2. I2C;
3. SPI;
4. NS16550 serial;
5. PCI and miniPCI;
6. Intel NOR StrataFlash X16 64Mbit PC28F640P30T85;
7. Graphics controller, Fujitsu MB86277.
Not supported so far:
1. StMICRO NAND512W3A2BN6E, 512 Mbit (supported with FSL UPM patches);
2. QE Serial UCCs (tested to not work with ucc_uart driver, reason
unknown, yet);
3. ADC AD7843 (tested to work, but support via device tree depends on
major SPI rework, GPIO API, etc);
4. FHCI USB (will send RFC patches soon).

Hello Kumar,
It would be great if we can get this into the 2.6.25.
Changes since v3:
- rebased against recent tree;
- compatible = "fsl,mpc8360-immr", "fsl,immr", "simple-bus";
- now "qe" node is the child of the "soc" node;
- proper #{address,size}-cells for the muram node;
- unused par_io node removed (in favour of upcoming GPIO support).
Thanks,

* [PATCH for 2.6.25 1/2] [NET] ucc_geth: fix module removal
From: Anton Vorontsov @ 2008-02-01 13:22 UTC (permalink / raw)
To: Li Yang, Jeff Garzik; +Cc: netdev, linuxppc-dev
- uccf should be set to NULL to not double-free memory on
subsequent calls;
- ind_hash_q and group_hash_q lists should be initialized in the
probe() function, instead of struct_init() (called by open()),
otherwise there will be an oops if ucc_geth_driver removed
prior 'ifconfig ethX up';
- add unregister_netdev();
- reorder geth_remove() steps.

Hi Li,
You kinda promised that these two patches would hit 2.6.25... ;-)
I've rebased the patches so they apply cleanly on the current tree.

* pthread / TQM5200 problem
From: Sebastian Theiss @ 2008-02-01 12:47 UTC (permalink / raw)
To: linuxppc-dev
Hi all.
I've been having some headache using the pthread library with a TB5200 =
box
(based on a TQM5200 board with a Freescale MPC5200 PowerPC-CPU). I =
created a
small program to pin down the problem and it runs fine on all my Unix- =
and
Linux-machines but fails on the embedded box: The program contains a =
class
CSignal that provides thread-synchronisation based on the
pthread_cond_signal and pthread_cond_wait calls and takes care of the
"spurious wakeup" and "lost signal" problems. The program runs 159
additional threads (that seems to be some internal limit), each of them
continuously increments a field variable and afterwards sleeps until the
main thread wakes it up again. The main thread monitors the whole field =
of
variables that are incremented by the 159 other threads and continuously
wakes them up. When running in the desired way, the program should show =
a
table with 160 entries and each entry (except for the last) should
continuously increase. However, on the box the threads 31 to 64 never =
wake
up, once they call pthread_cond_wait. The code below lacks some error
checking to keep it short, but besides that I don't see what's going =
wrong.
And, the code runs fine on my "real" Linux machines.
Any ideas of what the problem might be and how to fix it? Your I help =
would
be greatly appreciated as I'm rather despaired right now.
Regards,
Sebastian

When committing the patch "Implement arch disable/enable irq hooks" in
commit 7ac5dde99eb9fefdb526973c600075b7c5703a86 you changed the code to
always call the generic decrementer/interrupt enabling/disabling but
forgot to update the comment, this fixes that.

* 83xx immap_qe.h -> SIR type def error?
From: Russell McGuire @ 2008-02-01 11:47 UTC (permalink / raw)
To: linuxppc-embedded
In-Reply-To: <mailman.3.1201827605.31777.linuxppc-embedded@ozlabs.org>
All Freescale,
Not sure if this is the place to post this, but I have run across what I
consider to be a possible type error in the immap_qe.h file, for the
asm/powerpc branch.
In the file immap_qe.h
/* SI Routing Tables */
struct sir {
u8 tx[0x400];
u8 rx[0x400];
u8 res0[0x800];
}
Shouldn't these types be defined as __be16 ?
According to the Freescale manual this is a 16 bit field, not an 8-bit
field.
Spent an hour trying to figure out why I couldn't fill this field out with
upper 8 bits last night.
Thoughts?

* arch/powerpc 440GX external IRQ
From: Neil Wilson @ 2008-02-01 10:19 UTC (permalink / raw)
To: linuxppc-embedded
Hi,
Does anyone have these working and/or is able to talk me through the DTS
structure for them please ?
I have a 440GX board that works fine under arch/ppc with external
IRQ4,5,6 however I cannot get it correct in the DTS, I think I am not
correctly specifying the cascade of the UIC ? I started off using the
Taishan DTS as a template as that seems to be the only 440GX in
powerpc/platforms and can get the board to boot, mount NFS etc.
Thanks.
Neil

* External Interrupt
From: Marco Stornelli @ 2008-02-01 8:11 UTC (permalink / raw)
To: Linuxppc Embedded Mailing List
Hi,
I used the linux kernel 2.6.10 with a processor MPC8548E. I wrote a
driver for a device connected with the local bus. This device has an
external interrupt. In the local bus driver I have used the macro
MPC85xx_IRQ_EXT<X> to get the interrupt number and pass it to the
driver and after that register the ISR. Now with a kernel 2.6.21 this
macro isn't available because in the header file irq.h there is the
option CONFIG_PPC_MERGE that disable those options. I think this
problem is related to the migration of ppc code towards powerpc. I
know that now there is the new device tree source file where I can add
a device and its interrupt number but I think in this file I should
describe only the platform device, and this device is not a platform
device. Then, how can I get now this value? Is there some function to
call? How can I perform this operation?
Thanks in advance.
Marco

Seems that I was incorrect here. Tests showed that writing from Linux and then
reading back from U-Boot results in ECC errors. My comment above is bogus,
since nand_calculate_ecc() from nand_ecc.c is not used with HW-ECC generation
enabled.
I'll send a patch to fix this in a short while.

This is not the conventional format for board-level compatible

This looks like the old dodgy gianfar binding, and needs updating

I'm not entirely convinced on this two-level representation. I think
the FSL people need to get together and define a binding (or set of

The stock ticker is a recent convention. "dallas," has been used in

You're probably better off using a semaphore, or more specifically a
MUTEX, to protect the whole fop instead of a spin lock and the flags.
The semantics are simpler if do it with a mutex and the function can
sleep while holding it.

For sure these won't break it any worse. ;) Think of these more as a
janitorial thing vs. structural.
Doesn't gregkh's patch work? At least for the interim?
Jan-Bernd,
What tools are looking in sysfs? distro scripts? I don't see any link
between ethtool and the driver (other than the driver internal bits).
Am I missing something obvious?
