In this patchset, I enabled PINCTRL, DM_MMC, DM_GPIO and etc. Thanks, Peng. > >thanks! >-- >Jagan Teki >Free Software Engineer | www.openedev.com >U-Boot, Linux | Upstream Maintainer >Hyderabad, India. _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
