Two additional changes I neglected to mention: - added another tegra2->tegra20 rename for some new code that was added to arch/arm/cpu/armv7/start.S - rolled in the mkconfig fix that was breaking ARM platforms that don't define SoC -Allen -- nvpublic _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
