Hm.. did you do any profiling and are you really sure that the initial
console messages really contribute a significant amount to the boot
time?

On the MPC5121ADS board, U-Boot prints some 340 characters before you
can turn off the conssole using the usual methods. At 115200 bps this
takes about 30 milliseconds.

Are you really sure that it makes sense to optimize on thislevel yet?
Have you solved / accelerated all the other slow parts yet?

Attach a debugger. It should be trivial to see where U-Boot is
spinning.

I am pretty sure that what you are trying to do makes little sense.

The ideal situation is to have massive computing power right at home.
Something that dims the streetlights and shrinks the picture  on  the
neighbours' TVs when you boot it up.
