Ok, so we should be pretty safe to do the rename. I've cleared my tree from otehr patches, so will start on this. > The related question is however EABI support on pre-armv5 arhcs. > Koen, can you (possibly, once again ;-) ) elaborate, what we have > here.

Koen pointed me to the same old page regarding this: http://wiki.debian.org/ArmEabiPort . So yes, there're ways to support both armv4t and armv4 (i.e. thumb-less) archs with EABI. It's separate question when thumb-less CPUs will be actually supported, but all needed info for that is available. I also went to check what's the state of thumb support for CPUs used in consumer PocketPC and Palm devices, and (sorry if that's well known trivia) that only StrongARM SA1110 doesn't support thumb. I annotated http://handhelds.org/moin/moin.cgi/HandheldHardwareXref with that (well, I didn't really check OMAPs yet, but I'm sure they are thumb-able). > E -- Best regards, Paul mailto:pmiscml@gmail.com
