As discussed here [http://patchwork.ozlabs.org/patch/158202/] we want to use USE_PRIVATE_LIBGCC still.
However commit 5286f1ce dropped it regardless. Adding this back fixes a hang while handing over from SPL to U-Boot on Colibri T20.
This probably makes sense, but Allen should comment on this.
I wonder why I haven't seen any issue with this; perhaps SPL on all the boards I tested ended up not using any libgcc functions? But in that case, why would the Colibri board end up using them?
Could also be a toolchain issue. My normal workflow uses a toolchain without a libgcc, as we didn't needed it to this point. After porting over my changes to the new SPL boot I had to switch to a CodeSourcery toolchain containing a libgcc. So I'm not entirely sure where the problem lies, as I varied codebase and toolchain at one. But I confirmed that this patch works with both of my toolchains.
So yes, I'm really in favour of some comments.
Thanks, Lucas
