It runs from MASKROM so it's low level recovery, it's a means of
recovering the firmware to recover bricked devices, the OS is
irrelevant.
Reading about Rockchip recovery for other devices, it seems that
presents the device as a nonstandard USB device that requires a
vendor-specific driver and userspace tooling. I don't understand what
advantage this has over Tow Boot where you can just press Power + Volume
Up to expose the eMMC as a USB mass storage device then use good old
fashion dd.
