Booting process on n900:
1. Omap bootrom
2. Nokia X-Loader
3. Nokia NOLO Bootloader
4. Linux kernel
...

Nokia X-Loader and NOLO are stored in first nand part. It has size 128kB. 
Nokia X-Loader is signed (size 14.5kB), so cannot be replaced. NOLO bootloader 
is not signed (so theoretically can be replaced), but size is limited to 
113kB. I do not know how to compile U-Boot binary with size < 113kB...

Size of part where is stored linux kernel has 2MB and it is enought for U-Boot 
with kernel image (~200kB + ~1.6MB). Also U-Boot can boot kernel from eMMC/SD.
