[U-Boot] [PATCH u-boot v2 04/19] board: amlogic: move khadas-vim2 as q200 ref board

Thu Nov 22 09:07:25 UTC 2018

The Khadas vim2 derive from amlogic s912 reference design (Q200).

This patch moves the khadas-vim2 board support to a generic Q200 board,
while keeping a dedicated defconfig to customize the names and device tree.

+Image creation
+==============
+
+Amlogic doesn't provide sources for the firmware and for tools needed
+to create the bootloader image, so it is necessary to obtain them from
+the git tree published by the board vendor:
