Good question. I know this linker file is exactly the same as for 
arm926ejs, and I don't get the error with edminiv2 which is arm926ejs 
based; so it's not only different toolchains, it is also different 
boards or even different build environments.

Good question again.

For the moment we should focus on what happens when we use the current 
.lds -- it causes a linker error, right? Once we get this sorted out, 
we'll see if the build actually runs.

As for the linker error, I am sorry I got a bit lost: I know which 
toolchains you tried (2010q1 and 2009q1) but not exactly which codebase 
you build (is it v2010.12-rc2 ? master ? specific patches?) or which 
board you build. Please refresh me on this, so that I can reproduce the 
issue locally (I've got 2010q1 already installed).
