ARM64 – Odroid C2 U-Boot – More Progress..

Thanks to an additional U-Boot patch from Carlo Caione, it is now possible to (partially) boot the mainline Kernel from U-Boot on an eMMC module, as well as from SDcard..    Patch details here:  https://www.mail-archive.com/u-boot@lists.denx.de/msg213468.html

As I mentioned in an earlier article, it is not -yet – possible to boot the Kernel all the way from MMC devices, as support is not in the current (May 22) version of Linux-Next..
