Won't all board configs which use CONFIG_SYS_I2C_NOPROBES suffer from the same bug? I would hate to see an endless trickle of individual board config patches, and would much prefer a single patch to fix all boards in one go if you are willing to do it -- yes, it would touch boards that you cannot even test, but I'd say the risk is next to zero.
Wolfgang, Heiko, your opinion?

Isn;t this issue introduced just from commit

so ~1day old ... Hmm, I think, this is just a single board bugfix, as this warning only raises, if CONFIG_I2C_MULTI_BUS and CONFIG_SYS_I2C_NOPROBES is defined ... as introduced for the beagle board through above commit ... other boards should be clean, as I tend to do a MAKEALL after applying patches from ML ... but if you find time and can check this, it would be nice!

[sp] Yes, you are right about the issue, and hence I posted it as single patch against beagleboard only. The description includes a bash script that I used to "blindly" extent the fix to other boards.
I guess, MAKEALL succeeds because the appropriate config options may not be enabled for the boards.
Will dig on a few cases (of the ones changed) as to why the build succeeds.
time and can check this, it would be nice!
[sp] I only have a arm codesourcery toolchain installed. Would be able to check only ARM boards (of the 31) impacted by the updated patch.
Can do by tomorrow...

I confirmed that this fixes the above warning and builds and operates properly. As far as other platforms needing this type of patch, it seems there is a challenge in speaking for all of them, so I hope this patch can be applied.

Applied to u-boot-arm/master as it does fix the warning.
Note however that there is an error, independent from this patch, in building this board with ELDK42 and CS 2011q1 :

There is no omap_get_gpio_dataout() actually in u-boot, but it is called to get the value of the LED: state = omap_get_gpio_dataout(toggle_gpio);
Even if we had this function, it sounds odd to read the status of a LED (or generally from a GPIO set to output), because we should already know which value we have written before. Instead of reading from hardware should we not save the state of the LED in a variable ?

Albert,
The patch is in the TI tree.
We were having some issues w.r.t the GPIO.
Patches for this have been sent to the list. I was waiting for some testing to see whether the GPIO patches actually work.
Some issues seem to be present after rebasing with mainline but they don't seem to be GPIO related.
I'll send a pull request soon.
Regards, Sandeep

Hi Albert,
Note however that there is an error, independent from this
patch, in
building this board with ELDK42 and CS 2011q1 :

Anyone can reproduce and tell what the issue is?
I can reproduce it. IMHO this issue is introduced with the following commit:
commit b8bc8973a1830bb92e7a9bf3356dc209afb2f4e8 Author: Joel A Fernandesagnel.joel@gmail.com Date: Thu Aug 11 23:16:53 2011 -0500
There is no omap_get_gpio_dataout() actually in u-boot, but it is called to get the value of the LED: state = omap_get_gpio_dataout(toggle_gpio);
[sp] I reported the missing function few days ago: http://marc.info/?l=u-boot&m=131522045310324&w=2
~sanjeev
Apologies for not noticing.
Even if we had this function, it sounds odd to read the status of a LED (or generally from a GPIO set to output), because we should already know which value we have written before. Instead of reading from hardware should we not save the state of the LED in a variable ?
Actually, this is not that weird. All GPIOs I have dealt with can provide the value of their output, and I don't see what added value there is in storing their value in a RAM variable also.
True, this was discussed here hence the patch: http://lists.denx.de/pipermail/u-boot/2011-May/093068.html
What worries me, though, is that this commit is obviously dependent on other code changes that we don't have. Joel, can you help?
I hope from Sandeep's response, it is clarified that the new patch is not yet in explaining the undefined reference. Let me know if you need any other help from me. Thanks, Joel
