But we don't want to generate code for ARMv4 in general, but rather ARMv7 as the toolchain does. Only a tiny part of the code needs to be built for ARMv4, and in general we want to benefit from using ARMv7. -- nvpublic _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
