U-boot is a bootloader. A Linux kernel is completely separate from a bootloader. Typically, the bootloader (U-Boot, in your case) launches a Linux kernel, and may optionally set up a RAM based root filesystem (initrd) to be used by the kernel. Is the file you describe as rootfs.ext2.gz.uboot the Linux initrd?

If so, I will guess that you want to know either
  • How to cross compile applications for your target architecture
  • How to roll cross-built applications into an existing initrd root filesystem
  • Both of the above
Please clarify.
