We are now focusing on adding complete gta04 support to the Android 3.0
kernel. Only proper suspend/resume is missing.

Well, it was ported to several stable kernel revisions, 3.0 is just not
part of them. However I would appreciate some help from knowledgeable
people to complete 3.0 as well.

I doesn't really have the "greatest level of readiness", it had huge
suspend/resume issues and 3.0 is even working better on that regard.

We are not going to continue supporting 2.3 for any device (including
gta04). All efforts are put towards 4.0 as for now.
The current device tree is
http://git.paulk.fr/gitweb/?p=device_goldelico_gta04.git;a=shortlog;h=refs/heads/replicant-4.0
and will be pushed to gitorious soon.

I changed the script so that it does not reflash the NAND u-boot and
rather contains a fat32 partition with u-boot.bin, MLO, boot.scr and the
kernel. I also integrated the bootloaders build to the replicant build
platform.
