Hi all,
I pulled u-boot about an hour ago and master is at this commit:
Author: Matthias Weisser <weisserm@arcor.de> Date: Thu Nov 18 09:35:09 2010 +0100 Makefile: Fix build with USE_PRIVATE_LIBGCC(plus a small change in omap3_config.h - unrelated)
When trying to build u-boot I was constantly, getting these errors: arm-none-linux-gnueabi-ld: section .bss [8003f5c8 -> 8007e327] overlaps section .rel.dyn [8003f5c8 -> 80044e57] arm-none-linux-gnueabi-ld: section .dynsym [80044e58 -> 80044ef7] overlaps section .bss [8003f5c8 -> 8007e327] arm-none-linux-gnueabi-ld: u-boot: section .bss vma 0x8003f5c8 overlaps previous sections
Tried to build omap3_beagle and there were no issues; unable to debug for long, I decided to come back on this problem later. Opened a new window and started working on my Linux tree.
Returned back to u-boot, and this time build was successful for no evident change. Took me some time to realise that the toolchain I was using to work on Linux repo was different - I use an env script based on activity.
To verify the doubts, I explicitly ran this command with two different versions of toolchain in my path and I see different results. Here are last few lines of final build step

The configuration for beagle still build successfully for both toolchain versions. Any clues/ suggestions? Is there a recent change which hasn't yet been adapted or ported for omap3evm?
Here is my log of git-bisect: Was trying to find if any commit made changes that could be specific to toolchain version.
Due to state of the omap3evm, 2 changes in configs/omap3_evm.h had to be done manually at some stage - to avoid compile errors due to undefined symbols.

This points leads me to this commit:
commit 6d8962e814c15807dd6ac5757904be2a02d187b8 Author: Sebastien Carlier sebastien.carlier@gmail.com Date: Fri Nov 5 15:48:07 2010 +0100
Switch from archive libraries to partial linking
Is this related to toolchain version? Still doesn't explain why failure occurs for omap3_evm; not omap3_beagle...
