OK, this is kind of scary. What is wrong with those toolchains OR how we're telling them to build things as no, we should be able to use thumb mode just fine and need to for size reasons in various cases. If this is a generic problem then for example, omap4_panda + ELDK 5.4/5.6 just shouldn't work either and we _must_ use thumb there for at least SPL. -- Tom
