Dear ksi@koi8.net,

what compiler do you use? I just compiled all the davinci boards with GNUEABI GCC 4.4.1 (binutils ver.2.19.1) and I didn't get a single compiler warning.
I was playing with old tool chains actually. That was with gcc 3.3.x.
Ah, that's ancient... I don't think we need to something for this. I betcha it won't compile at all with something like 2.x.x but who cares? :)
There are 2 separate issues but they are not related to the above description.
First is that it fails to compile with GNUEABI GCC but that is addressed in your recent arm build patch that works OK.
Thanks for the confirmation! Much appreciated. Could you please send an Ack-by or Tested-by for that patch? Thanks in advance.
Sure I will.
The second one is that GCC 4.4.1 (don't know about the older ones, don't have those on my machine now) generates an error for inline weak functions in lib_arm/board.c (and I think it is totally correct -- what is an inline weak function?) Here is the failed build log excertpt:
A patch for this has been posted some time ago. See http://thread.gmane.org/gmane.comp.boot-loaders.u-boot/65397/focus=65559
we're just waiting for the ARM custodian to take appropriate action.
OK.
As for those "duplicate `volatile'" warnings I don't see them (and have never seen them before) so I don't know what to fix.
I can send you my build logs off the list if you want.
Well, here is an example - building davinci_schmoogie using ELDK 3.1.1 (gcc version 3.3.3):
davinci_emac.c:82: warning: duplicate `volatile' davinci_emac.c:83: warning: duplicate `volatile' davinci_emac.c:84: warning: duplicate `volatile' davinci_emac.c:85: warning: duplicate `volatile' davinci_emac.c: In function `davinci_eth_open': davinci_emac.c:257: warning: duplicate `volatile' davinci_emac.c: In function `davinci_eth_rcv_packet': davinci_emac.c:475: warning: duplicate `volatile' davinci_emac.c:476: warning: duplicate `volatile' davinci_emac.c:477: warning: duplicate `volatile' davinci_emac.c:496: warning: duplicate `volatile'
Once again -- I don't think it requires any action. It builds without a single warning with newer compilers, even with 4.2.x less for 4.4.1...
