[U-Boot] How to specific where to extract the linux kernel and romfs file system

[Szentpétery István]

Hello

I'm having some trouble whit Micro-Blox LPC 2478.
I'm loading uLinux.bin to the flash address 80000000 and cramfs.img to
the addres 80200000.
This is oke but when it extracts to the ram i suppose then its starts
at address a1500000 for the linux and at address a1800000 for the
romfs.img but the romfs image is more than 2 mbyte because the ram is
only 32 mbyte so it doesn't fit in the ram.
How can i change where to extract the linux kernel and the file
system, and mount to linux ?
Thanx.
