That's no surprise, since U-Boot links libgcc into itself. And since PXA2xx is armv5-compatible, you'd need armv5 toolchain. The hang you're observing is most likely happening in some aeabi_* function pulled in from libgcc, which contains some armv7 instruction(s), which in turn upsets the xscale. I would suggest that we drop this patch, but I would also suggest that we do the same thing kernel does and just enable CONFIG_USE_PRIVATE_LIBGCC globally for everyone to break this constant nonsensical influx of toolchain-related problems. This nonsense has been dragging on for too long. Tom?

This nonsense has been dragging on for too long. Tom? Albert? I don't really care how this gets fixed I just don't ever want to have to debug through that one ever again! Thanks, Marek.

I've been there, multiple times. I can feel your pain, this is a terrible nastiness with the libgcc. > Thanks, Marek. Best regards, Marek Vasut

Fix boot hang caused by incompatible libgcc which has been observed when using later Linaro toolchains like gcc-linaro-arm-linux-gnueabihf-2012.09-20120921_linux or gcc-linaro-4.9-2014.11-x86_64_arm-linux-gnueabihf.
