The parallel flash is 2 Mb. Here you can store u-boot and a linux kernel
as written in the u-boot manual. For a root fs, the space is not very big...

Another possibility is, to use the serial dataflash for everything,
which is 8Mb. This procedure seems to be unsupported by u-boot, since it
copies u-boot from serial dataflash to RAM and starts it, but it works
for me. Initialization of processor and RAM ist done in this case by a
pre-bootloader (romboot).

The procedure is described here:
