You must be doing something badly wrong. It should be  more  than  10
times  faster.  I  just  veryfied  that the download of a 606109 byte
image on a MPC8xx at a console baudrate of 115200 bps takes less than
70 seconds (1 minute 8.7 sec to be exact).

On faster systems, you can probably also up the console baudrate.

Yes, of course you can. Run U-Boot, and when  it  displays  a  prompt
type  "halt"  at  the  BDI, then use the load command to download the
image, and then type "go" to continue in U-Boot (probably to  run  an
"imi" command to verify the download.

Best regards,
