From: Andreas Färber <afaerber@suse.de>

The GeekBox is a TV box from GeekBuying, based on an MXM3 module.
The module can be used with base boards such as the GeekBox Landingship.

This adds basic support to chain-load U-Boot from Rockchip's miniloader.

$ ./lollipop_u-boot/tools/loaderimage --pack u-boot.bin u-boot.img

Implemented is the serial console, but no boot media drivers yet.

Note that flashing the resulting U-Boot will not allow you to enter the
rockusb mode any more via "Update" button. Instead, you will need to
short two pins on the bottom of the module to enter MaskRom mode and
re-flash the loader:

Hi Andy,

Sorry for forgetting about this, and thank you for picking it up.

One reason this series stalled is that I was asked to add a README
instead of the text in the commit message - this is still missing in
your submission, it seems.

     Thanks for pointing out this, I will add a README in next version.
