We are working on the new u-boot porting for XU4 boards.
Here is the source code of the new u-boot.
https://github.com/hardkernel/u-boot/tree/odroidxu4-v2017.05
What we can do with the new u-boot !
1. Enabling the HYP mode for the KVM virtualization with Kernel 4.9 LTS.
2. Enabling the Ethernet device to support the TFTP/PXE remote booting.
3. Booting from various new eMMC chipsets.
4. fatload / ext4load commands are available natively.
5. And many other new features.
We will release a update package in next week for Linux/Ubuntu users.
We are implementing a few more functions(for example, the fastboot protocol) for Android 4.4 and Android 7.1 now.
