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:
