Warning

Sanjeev, Sandeep,

I see a lot of this warning in many OMAP boards:

---------------------
Configuring for omap4_sdp4430 board...
gpio.c: In function 'omap_get_gpio_dataout':
gpio.c:161: warning: assignment discards qualifiers from pointer target type
---------------------

Commit 5c2684dbebe9df47ea0a1865ed94db7886ea5941, I assume, is what brought this in, but I cannot verify this right now, as I am in the middle of aMAKEALL arm.

Can someone look up what causes this warning?

Amicalement,

Albert.

[sp] I just started looking into this.
Expect a response in next 30 mins.

Albert,

Which branch are you seeing this warning on?

I was able to build the u-boot successfully for "omap4_sdp4430" using codesourcery 2011.03-41 and codesourcery2009q1-203 on the u-boot-arm/master at:

4f02fba : omap4: fix pad configuration settings for SDP and Panda 3e90493 : omap4: IO settings
a5b6a6c : omap4: make SDRAM init work for ES1.0 silicon e5c06a0 : omap4: factor out common part from board config headers 9a18112 : omap: gpio: Adapt board files to use generic API d7605af : omap: gpio: generic changes after changing API 5b5c435 : omap: gpio: Use generic API
c7a993f : led: remove camel casing of led identifiers globally

Infact, the function "omap_get_gpio_dataout" shouldn't exist as it was replaced with generic gpio API in commit "5b5c435" listed above.

Believeing that you were trying to build the u-boot master, I tried to check there, but always get stuck with different errors:

premi # make omap4_sdp4430_config
Configuring for omap4_sdp4430 board...
premi # make > bld-master.log

Couldn't find this commit in my repo may be, because I am tracking only master. But wasn't able to find via gitweb either on:
http://git.denx.de/?p=u-boot/u-boot-arm.git;a=shortlog

~sanjeev

It appears the .depend files are not getting cleaned by distclean. When I deleted them manually, I was able to build for omap3_evm_config but then faced similar problem when building for omap4_sdp4430_config.

Here is the log from my work session:

Dear "Premi, Sanjeev",

This would then be another bug that needs to be fixed.

Note: you can try "git clean -n -x" to find any files not registered in the git repo; after a "make distclean" no such files must exist. [And you can use "git clean -f -x" to actually delete any such files.]

Best regards,

Wolfgang Denk
