* Re: [PATCH v2] Add support for the digsy MTC board.
From: Grant Likely @ 2009-02-02 19:26 UTC (permalink / raw)
To: Grzegorz Bernacki; +Cc: linuxppc-dev
In-Reply-To: <12335905121539-git-send-email-gjb@semihalf.com>
Hey Grzegorz,
I've pulled your patch into my -next tree, but I made a few changes first:
- I dropped the defconfig changes because they conflict with the
defconfig update that Ben just pulled from me
- I updated the .dts file to reflect changes I was already making to
all the other .dts files
- I added the digsy-mtc board to the Kconfig documentation.
I've pushed my whole queue of changes out to my -next tree. Please
pull it down and try it out. (Note, this tree will get rebased at
least once before I ask Ben to pull it, so be aware). Make sure that
I haven't broken your .dts file. To get the defconfig change in, you
can either send me another patch with just the defconfig change, or
you can pop my version of your patch off the top of my -next tree and
rebase your entire patch on top it. Whatever you prefer.
One more note; the new digsy-mtc.dts file from my tree will probably
not work with older kernels. Kernels need to be backward compatible
with older .dts files, but the same is not true for the other way
around.
Here's my -next tree:

Do we just want to dump the wrappers, instead?

* How to Enable MTD
From: mike zheng @ 2009-02-02 17:45 UTC (permalink / raw)
To: linuxppc-dev
Hello,
I have one AMD29LV640 NOR chip on my system. How can I enable it in
Linux as MTD device? Right now, I can not operate on /dev/mtd in
Linux:
# od -x /dev/mtd
od: /dev/mtd: No such file or directory
od: /dev/mtd: Bad file descriptor
# od -x /dev/mtd0
od: Dec 31 16:02:17 kernel: MTD_open
/dev/mtd0: No such device
I think something wrong with my config flags(listed as followings),
this is a CFI supported device. The physical address starts at
0xbf800000
Thanks for your help,
Mike

* [PATCH] i2c: i2c-ibm_iic message can be confusing
From: Sean MacLennan @ 2009-02-02 17:01 UTC (permalink / raw)
To: linuxppc-dev, Jean Delvare, ben-linux
This is a trivial patch that does not need to be in 2.6.29. While
tracking down an EEPROM problem, I found the messages confusing... it
looked like the EEPROM was being started before the I2C driver!
Here is an example:
at24 0-0052: 512 byte 24c04 EEPROM (writable)
ibm-iic ef600700.i2c: using standard (100 kHz) mode
ad7414 0-004a: chip found
It looks like the at24 starts first, then the i2c driver, then the
ad7414. By moving the message to after the of scan, we always get the
driver, then the devices.
Cheers,
Sean
Print the i2c driver message before scanning for devices so that the
logs show the driver, then the devices. Currently you can get
device(s), driver, device(s).

I enabled CONFIG_EEPROM_LEGACY in my defconfig and I can see eeprom

On my board, I get the following:
ata1: PATA max PIO6 mmio cmd 0x1c1000000 ctl 0x1c1000098 irq 32
Note that the addresses I provided got turned into 36-bit addresses
because I am using a PPC440EPx chip.
I am suspicious of the addresses you got, but I don't know enough
about how the mpc8248 sets up its memory map. Perhaps someone with
knowledge of that chip can comment.
Have you hooked a logic analyzer to the device? You should be sure
that the chip selects are really responding at the reported addresses.
Since the CF works with Uboot, at least we know the hardware is good.

I am seeing a problem where if I enable CONFIG_EEPROM_LEGACY and
CONFIG_EEPROM_AT24, then the at24 driver does not work. Would you mind

Does it only happen at mount time? We get this quite often at work,
but it never happens at home. I assumed it was just due to the flaky
networking at work.

From: Grzegorz Bernacki @ 2009-02-02 16:01 UTC (permalink / raw)
To: linuxppc-dev
This is the InterControl custom device based on the MPC5200B chip.
Signed-off-by: Grzegorz Bernacki <gjb@semihalf.com>
---
Version 2:
- change name in DTS and remove unnecessary fields
- use mpc5200_simple.c file instead of dedicated file for digsy_mtc
- update mpc5200_defconfig:
- add support for RTC (ds1339)
- add support for LXT PHY
- add support for eeprom AT24
- add support for MTD partitioning based on OF description
- some updates automatically generated by 'make menuconfig'

That's was today's "little" task. I was just in the process of writing an email :-)
It got me to the following commit:
commit 64b3d0e8122b422e879b23d42f9e0e8efbbf9744
Author: Benjamin Herrenschmidt <benh@kernel.crashing.org>
powerpc/mm: Rework usage of _PAGE_COHERENT/NO_CACHE/GUARDED
I tried reverting it, but as I had kinda thought, that really didn't help.
I'm just recompiling to check that I didn't screw-up during the bisection.

The second register set does not start at register 0. It starts
at register 6. We are using 1 chip select from the processor,
and generate two chip selects to the CF that are 0x80 apart (on
a sequoia board).
So here is what I am using on the modified sequoia board. Note
the 0x00000098 - you might think it should be 0x00000080 as per
the discussion above, but because the second register set starts
at 6, you have to build that into the address. =20

Hello Greg,
Can you please look into these patches? I think they all are 2.6.29
material, since the QE UDC driver is barely usable w/o these fixes.
Thanks,
p.s. And thank you for merging the FHCI driver!
