I have looked at your work and tried the images,its good work done by you
guys.

Currently I have android booting to console with dmart's
kernel<http://git.linaro.org/gitweb?p=people/dmart/linux-2.6-arm.git;a=shortlog;h=refs/heads/arm/vexpressdt-rtsm>plus
androidization
topic branch<http://git.linaro.org/gitweb?p=people/andygreen/kernel-tilt.git;a=shortlog;h=refs/heads/linaro-androidization-tracking>.
GUI is crashing since CLCD driver is not working with device tree. I have
also seen that mmc (less than 2 GB image ) performance is much better than
NFS. I could use adb over TCP.

We have a different patch to get around the missing OpenGLES support. But
the performance while using our
patch<http://review.android.git.linaro.org/#change,1260>and the set of
patches you mentioned could be very different.

If you need further details please let me know.
