[sp] Are you referring to this patch?
http://git.denx.de/?p=u-boot.git;a=commitdiff;h=aaeb0a890a050b58be87fa2b165eec5fa947dc86

I see the change for arm926ejs/u-boot.lds and armv7/u-boot.lds
to be similar.

Your commit mentions about the new ld vs. old; I had seen this
earlier as well. It was the reason for me to try CodeSourcery
Lite 2010-q1 but there I get a different error - mentioned in my
first post.

Which toolchain version are you using?
