Hello Hans,
This patch is base on u-boot-sunxi next.
I see it's far behind the u-boot master.
Aren't we using u-boot-sunxi next ?(

As axp818 ALDO support is enabled, it causes bpi-m3 fail to boot
if ALDOs are set to 0.

Hello,
I forgot to post this patch, Thanks to Kevin Chua Soon Jia
who reported that latest mainline u-boot fail to boot and reminded me to post
it.
For Banana-pi m3, ALDO must not be set to zero, default settings are same as
mentioned Sinovoip Bpi-m3 schematic.

Add dts and defconfig for Banana-pi M3 board.
It has 2G LPDDR3, UART, ethernet, USB, HDMI, USB Sata, MIPI DSI,

It is paired with AXP813 PMIC which is almost same as AXP818.
