This bbclass was taken from the Rockchip team's work at
53d2e2e474
It was mostly written by Jacob Chen <jacob-chen@iotwrt.com>. I've made some
small modifications and added it.
Older images used (what Rockchip calls) the "legacy parameter" format. Newer
images use u-boot and a GPT partitioning scheme. This class allows the build
to generate a gpt-img file that can either be flashed to eMMC or written to an
SDcard (the same image is used for both).
This is the new image format used for rk3288 SoCs (e.g. the Firefly board).
