[U-Boot-Users] Extremely tiny footprint

[Laurent Pinchart]

Hi everybody,

I would like to use U-Boot as a first-stage boot loader to program flash 
memory on the target board. The idea is to perform a two-steps procedure:

1. Program the first-stage boot loader in flash using JTAG (slow)
2. The first-stage boot loader downloads the final boot loader (full-featured 
U-Boot) using TFTP and writes it to flash (fast)

To minimize time spent in step one, I need to make the first-stage boot loader 
as small as possible (hopefully less than 32kB). Has anyone ever stripped 
U-Boot that much ? Is there any documentation available ?
