Allwinner H3 framebuffer console support
Hi folks --
As part of the CHIP port, I added support for the "simplefb" DT bindings.
This allows the kernel to take over a framebuffer setup by the bootloader.
I've just added a patch to our U-Boot to enable simplefb support for sunxi
socs using the newer DE2 display device and added the framebuffer node to
our sun8i-h3 dts template to activate it.
If you update your kernel and dtb, upgrade U-Boot (2017.07nb1 for
orangepi-plus2e and orangepi-2), and plug in HDMI before powering on the
board, you should have a working framebuffer. Serial console is
still the default; you can override it by adding console=fb to bootargs in
U-Boot. The usual things (Xorg etc) will work also as simplefb is built on
top of genfb/wsfb.
