[U-Boot-Users] Download of kernel Image through Serial Line.

I may be want to try to put U-Boot with a Embedded Linux on
a custom MPC860 (33Mhz) board of course with Network (10 Mbps)
( 2MB ROM, 8 ou 16 MB of Flash, 4 MB of DRAM for the system, 16 MB of SRAM
for the application )

So for U-Boot and Linux, I want to allow only the DRAM
and a part of the flash ( example : 8 MB )

Is it possible to have U-Boot and the kernel linux in the prom
without decompress the kernel in RAM ? Flash will be ok for the
filesystem and my application. The SRAM should be use
for my application Data Base.

Is it enought with network support ?

The smallest demo we have in our ElinOS Distribution has a ROM
footprint of less than 256KB. Of course that is a _very_ _simple_
system. You should calculate with 512KB-1MB.
