You end up compiling more code than necessary if PM_SLEEP is disabled
but PM is enabled (i.e. runtime powermanagement enabled but no sleep
states)

* linux2.6.17.4 with temac patch running on ML403 hung while initializing from ramdisk
From: angelalinyao @ 2007-08-29 11:12 UTC (permalink / raw)
To: Linuxppc-embedded
Hi, all
I have run linux-xilinx-26.git based on kernel 2.6.17.4 on ML403 successfully.
Then I used a temac patch from mvista (PAULUS)
The system hung while initializing from ramdisk after patched.
I use plb-temac v3.00a and hard_temac v3.00b, with EDK 9.1
The message printed is as follow. Any help would be appreciated.

What names would you suggest? DDR_DENALI_... looks too long :)
The names have been taken from the docs, I've just prefixed them with DDR_.

I wasn't talking about DDR_GET_VAL. I meant having the DDR registers
defines just as "DDR_START", "DDR_START_SHIFT", etc could be confusing
later.
But I don't really see a need to change it at the moment. We can
prefix the with something else if a conflicting DDR controller ever
shows up.

It's such a generic macro and not Denali or even SDRAM specific. So it really
should be no problem to keep it as is.
Just my 0.02$.

I checked this. I think the TQM5200 is really hanging after the ...OK
because I have activated the telnet server and normally I'm able to
connect to the device after booting via ethernet. No ping, no telnet.
With an older 2.6.19.2 kernel this was O.K.

I'm using U-Boot 1.2.0-gbc2b9c33-dirty (Feb 22 2007 - 09:53:14). Is that
recent enough? (I don't know exactly what you mean with "99c2fdab", is
this the second number after "1.2.0-"?)

Maybe the problem is the missing tqm5200.dtb file. I have booted the
kernel without it (just bootm 200000). Does the kernel need this file? I
found a tqm5200.dts file the the kernel sources, but the device tree
compiler (dtc) seems not to be in the 4.1 ELDK. Do I have to install
this compiler and build the appropriate dtb file?

In older kernels it was O.K. just to uncheck the SM501 drivers in the
kernel configuration. Has this changed?

But then boards would have to deselect rather than select the option...
can kconfig do that?

Enh... it doesn't convey any new information, and in practice, it's done
by common CPM code that doesn't know about the individual device's node
anyway.

It has a phandle to the phy node... if you mean the mdio bus node, why?

There's existing code that pins the IMMR when that option is enabled.
It's a bit broken, but there's a patch in the 8xx series that fixes it.

The assumption was that CPM1 and CPM2 are never going to both be enabled,
as CPM1 only exists on hardware with a unique MMU.
I could add an obj-y += $(obj-yy) if you like, though.

Well, I was hoping that more consolidation between cpm1 and cpm2 (and
qe/cpm3, for that matter) would happen in the future, and this would be a
place to put it.

Yeah, you don't want a symlink, you want a console device node instead:

mknod /dev/console 5 1

I would say you need to add a /dev/null device node, or fix it's

Ah-HA! You're using the wrong type of kernel image. When booting
from u-boot, you should be using a 'uImage', not a 'zImage.elf'.
(generated with 'make uImage' in the kernel tree). An you should use
the 'bootm' command to boot the kernel.
With bootm, u-boot can pass parameters to the kernel and it is u-boot
that does the uncompression (instead of the zImage wrapper).
Cheers,
g.

Hi Grant,
Yes you are right that I should use uImage instead of zImage.elf
I have tried first bootm and uImage but it also hanged during
uncompression so next I have tried bootelf zImage.elf to see how this
works because I was able to run zImage.elf straight from EDK via jtag.
Cheers

I have done further investigation with bootelf and zImage.elf (from
u-boot) and it seems to be that the system fails during image
uncompression: The last command executed is: r = zlib_inflate(&s,
Z_FINISH); /* file: ./arch/ppc/boot/common/misc-common.c */
zlib_inflate function code is in ./lib/zlib_inflate/inflate.c

* [PATCH 2.6.23] ibmebus: Prevent bus_id collisions
From: Joachim Fenkes @ 2007-08-29 16:15 UTC (permalink / raw)
To: LinuxPPC-Dev, LKML, Paul Mackerras
Cc: Thomas Klein, Paul Mackerras, Jan-Bernd Themann, Christoph Raisch,
Stefan Roscher
Previously, ibmebus derived a device's bus_id from its location code. The
location code is not guaranteed to be unique, so we might get bus_id
collisions if two devices share the same location code. The OFDT full_name,
however, is unique, so we use that instead.
Signed-off-by: Joachim Fenkes <fenkes@de.ibm.com>
---
The patch has been tested and works fine. If you think it's too much change
for 2.6.23-rc5, please schedule for 2.6.24 instead.

* 2.6 kernel hangs after loading device tree
From: charanya venkatraman @ 2007-08-29 16:38 UTC (permalink / raw)
To: Linuxppc-embedded
[-- Attachment #1: Type: text/plain, Size: 1064 bytes --]
Hi all
Sorry about the previous mail.Got sent by mistake.
Iam using the 2.6.22.5 kernel on MPC 8560 and MPC8540 on my custom
board.Mykernel hangs after loading the device tree in both the
processors .There is
no output on the serial port after loading the device tree.Am using U-boot
1.2.0 as the bootloader.After enabling debug in u-boot i could see that the
control is getting transferred to the kernel after which it hangs.Earlier i
tried using 2.6.21 which also hangs at the same point.The config files used
were MPC8540ADS_defconfig and MPC8560ADS_defconfig under powerpc directory.
The changes that were made to the device tree are:
1.The reg and ranges properties of the soc node have been changed to account
for the change in CCSRBAR of my board.
2.Removed the PCI,mdio nodes and ethernet nodes since i dont need support
for these as of now.
I have tried the following console arguments:
MPC8540: bootargs root=/dev/ram rw console=ttyS0,115200
MPC8560:bootargs root=/dev/ram rw console=ttyCPM0,115200
Any help on this issue??
Thanks.
Charanya.
