ppc: Fix build of m82xx_pci
A recent patch updated the name of pci_assign_all_busses to
pci_assign_all_buses. This instance of its use wasn't corrected
by the original patch to use the new name.
Builds cleanly on ads8272.

* segmentation fault on bnslr instruction
From: Vijay Sampath @ 2005-10-24 18:49 UTC (permalink / raw)
To: linuxppc-embedded
Hi,
I am running an embedded linux (kernel 2.4.18) system with a bunch of
multithreaded applications compiled using uClibc (0.9.26). I have
noticed that very occasionally a couple of the processes die with a
segmentation fault. The core file points to the process dying on the
bnslr instruction inside the uClibc library code immediately after a
system call. I don't know why the system returned from the system
call, because nothing should have been going on at the time and the
process should have been sleeping in kernel space on the accept call.
Would like any pointers from people more knowledgeable on the ppc
architecture as to why a bnslr instruction would cause a segmentation
fault (the LR register is correct). I am assuming that the registers
saved by the OS when the fault occurred are precise (at the instant of
the fault and not sometime after). Also it bothers me as to why the OS
returned from the system call, as there was no activity going on.
Attached below is some debugging info using gdb.
Thanks,
Vijay

This is correct. TQ uses the same eval board for all TQM83xx and
TQM85xx modules. It was originally developed for the TQM85xx so it
got named STK85xx (STarter Kit 85xx). Later, it was impossible to
reflect the use for the TQM83xx in the name of the eval board. Yes,
this is confusing...

I already did so. Included here for completeness. Let me know if this

What do you mean? We set vendor as "Freescale Inc." - isn't this
correct for the MPC8349 CPU? What schould it be?

Thanks.
Ummm... what about my earlier patch for the PPChameleonEVB board?

Andy, Kumar
Thank you for your help!
GDAtech only give me linux-2.4.27 binary file for RMC-G8500 card, I try to port 2.6.13 for that card myself.
Today, I download linux-2.6.13.tar.bz2 and patch-2.6.14-rc5.bz2 from kernel.org.
I download http://lwn.net/Articles/146253/ "Patch: Gianfar PHY Layer Update".
I download http://ozlabs.org/pipermail/linuxppc-embedded/2005-October/020593.html "[PATCH] 85xx PHY Platform Update"
I patch and build them together get a linux 2.6.14-rc5 for MPC8540, try it on RMC-G8500 card

Maybe there's something with SOF generation - check if RCCR[EIE] is set.
Just a pure guess...

* m82xxhci USB driver problems
From: Alex Zeffertt @ 2005-10-24 16:07 UTC (permalink / raw)
To: linuxppc-embedded
Hi list,
I'm trying to get the m82xxhci USB host controller driver working on
my MPC8272ADS board, and linux-2.4.25.
I can compile and modprobe the module. When I insert a USB pen drive
I get the following message:
# hub.c: new USB device m8xxhci-1, assigned address 4
Manufacturer:
Product: USB Disk Pro
SerialNumber: 07531E630012
scsi0 : SCSI emulation for USB Mass Storage devices
Which looks okay. But after a long delay I get:
# usb_control/bulk_msg: timeout
Then after another delay:
# usb-storage: host_reset() requested but not implemented
#
Then after another delay:
# scsi: device set offline - command error recover failed: host 0
channel 0 id 0 lun 0
After this final message, but not before, the pen drive device appears
in /proc/bus/usb/devices:
# cat /proc/bus/usb/devices
T: Bus=01 Lev=00 Prnt=00 Port=00 Cnt=00 Dev#= 1 Spd=12 MxCh= 1

Does anybody have any idea what could be causing this problem? The
HCI is clearly able to communicate with the device because it
identifies it. But I don't know why the timeout should occur!

I'm a bit confused by the statement above. The code you present is
from gianfar.c, and is certainly not a bug. It is possible you are
using an older version of the code, which has a bug, which is fixed
by adding these lines above the code you show:
tempval = gfar_read(&priv->regs->dmactrl);
tempval &= ~(DMACTRL_GRS | DMACTRL_GTS);
gfar_write(&priv->regs->dmactrl, tempval);
This fixes a problem where setting GRS and GTS when they're already
set doesn't initiate the graceful stop. But if you are using 2.6.13,
you should have this fix. I suspect that, like I told Junita, you
need to make sure the platform code has the right CCSRBAR value set up.

I'm not familiar with this card. Are you sure there's support for it
in your source tree?

* Re: [Patch] Add support for TQM834x Boards
From: Kumar Gala @ 2005-10-24 15:16 UTC (permalink / raw)
To: Wolfgang Denk; +Cc: linuxppc-dev
In-Reply-To: <20051022220612.7F2F3353D84@atlas.denx.de>
Wolfgang,
Will you or Marian being maintaining this board family going forward?
Also, you need to split out the MTD portion and submit that to the
MTD maintainer separately.
The only other comment is that tqm834x_show_cpuinfo() might want to
be updated the vendor info.
Otherwise, once the I2C DS1337 patch is ack'd I'll push this upstream.

This patch implies that PAL (Phy Abstraction layer) is utilized within
the gianfar driver, but this change is just queued upstream (AFAIK - or
in the netdev tree) right now. In order to use this you should wait a

Well, it really doesn't have anything to do with ADB. The problem is
actually the macio bus layer, but we don't have CONFIG_ options for
that. I've been working on getting the macio code running in 68k,
so I was thinking of introducing a CONFIG_MACIO. Would this be an
acceptable option? On 68k, I would just default it to yes if the
config has CONFIG_MAC, but it could be made a real question for ppc
since the platform stuff doesn't really let you select just a pci
powermac kernel anymore. Any comments?
I suppose if anyone still has one of those old CHRP machines, we
could probably get hydra supported by macio_asic to get some of the
other drivers working on it.

Sorry to disturbed you. I find your question in the http://ozlabs.org mail list.
Have you fixed the bug in gianfar_phy.c?
tempval = gfar_read(&priv-> regs-> dmactrl);
tempval |= (DMACTRL_GRS | DMACTRL_GTS);
gfar_write(&priv-> regs-> dmactrl, tempval);
while (!(gfar_read(&priv-> regs-> ievent) & (IEVENT_GRSC | IEVENT_GTSC)))
cpu_relax();
/* Reset MAC layer */
gfar_write(&priv-> regs-> maccfg1, MACCFG1_SOFT_RESET);
I buy a RMC-G8500 card from GDAtech, I try to build linux-2.6.13.4 from kernel.org and meet the same problems as you had. I test the same code on freescale 8540_ADS board, it is good.Can you share some infomation of your progress?
Thank you!
