From: Yann Dirson <yann@...>

This is a RK3328 board from Pine64.
Board details at https://wiki.pine64.org/wiki/ROCK64.

Default image is built to boot from SD-card. Building an image for
eMMC requires to set RK_BOOT_DEVICE=3D"mmcblk0".

This is just basic initial support without a kernel BSP. As is the
board boots with a serial console.

Note I had to create the SoC definition for rk3328, and rather than
setting serial at 115200 there just to have the board definition
override it with rockchip-standard 1500000 I've set the latter right
in rk3328.inc.

Changes in v2:
- include Ayufan's patch for mmc aliases so presence of eMMC won't
prevent booting from SD
