Hi Khem,
I've made tangential progress!!
I found out that Denx had a bunch of pre-built rootfilesystems, generated from
yocto/denzil branch.
I took the core-image-core-generic-powerpc-4xx-softfloat.tar.gz from the
following location:
ftp://ftp.denx.de/pub/eldk/5.2.1/targets/powerpc-4xx-softfloat
I used the linux-xilinx-3.3.0 kernel that I built earlier (since the linux
sources are independent) with gcc-4.5.1, and use the pre-build root filesystem,
and guess what, I get the bash prompt!!

The following link gives some useful information about ELDK 5.2.1:
http://www.denx.de/wiki/ELDK-5/WebHome
Looking at the denx git repository for the eldk-5.2.1 branch, you find that the
eglibc recipes for the denzil branch are still at 2.13 and 2.15
http://git.denx.de/?p=eldk.git;a=tree;f=meta/recipes-core/eglibc;h=9e2d141f608f42b259651ec928efde803f1dd077;hb=refs/heads/eldk-rel-v5.2
In conclusion, one potential solution exists, which is to use the ELDK repo,
and build the ELDK toolchain for my target.
However, I will continue to try to find out why the current yocto master repo
is failing, and try to see if I can isolate the problem.
I've just finished rebuilding yocto/master with gcc-4.5.1 and eglibc-2.13. So
will test it out and let you know how it goes!
Thanks for all your help and patience!!
Best regards,
Elvis Dowson_______________________________________________
