Actually, I *am* looking for system level customisations; I want to use USB downloader mode to drop a binary into memory and jump to it, so that the binary runs without any OS. (I have a background in embedded systems so am used to this.)

I'm looking for a simple starting point simply to avoid the long and tedious process of trying to figure out from the u-boot code how to initialise DRAM, set up the serial port, etc.

You mention the kernel --- I did see a reference to a kexec-capable kernel, but it was intended to get written to flash and then be booted from via u-boot. Do you know of one which can be deployed and booted directly by the USB downloader? Because if so, I'd be really, really interested in that.
