Are there any comments on this series? I'm particularly interested in comments on include/serial.h - the uclass API for serial. I plan to apply the uclass and sandbox support soon, with exynos support coming later once the 'common' serial has been reviewed. http://patchwork.ozlabs.org/patch/372891/ Regards, Simon _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
