Dear Tom Rini,

So, the (normally?) required to work toolchains are ELDK 5.1 and ELDK 4.2. 5.1 is fine but with 4.2 (gcc 4.2.2) we get two warnings for every file about interworking/thumb not being supported. Further, the resulting binary doesn't boot.
However, is this really a problem? I don't imagine folks using ELDK 4.2-era tools on OMAP5, and I have a tough time imaging them using it for OMAP4.
I don't consider it a big problem (just a bit sad) if ELDK 4.2 cannot be used for building these. However, I think it is not acceptable tobuild known-to-be-broken images. If the tool chain is too old, this shall result in a clear error message and abort of the build.
Why is thumb mode needed for these boards? Just because of image size?
Best regards,
Wolfgang Denk
