git-bisect tells me that your patch (or whatever version of it was actually applied) causes this linker warning: powerpc-linux-gnu-ld: Warning: lib_powerpc/fpu/libpostpowerpcfpu.o uses hard float, libpost.o uses soft float See this thread for details: http://lists.denx.de/pipermail/u-boot/2011-January/085811.html I have no idea how to fix this. -- Timur Tabi Linux kernel developer at Freescale _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
