[U-Boot] is it possilbe to have uboot find the kernel in the file system?

[John Stile]

Is it possible to add my kernel to the rootfs partition rather than have
a separate partition? 

I am using U-Boot 1.3.4, on a at91sam9g20ek (256Mb Nand, 8Mb Nor), and
use the sam-ba firmware upload tool. 

I'd like to put everything on nand, ignore nor, and hold redundant
areas, in perpetration for firmware updates.

My starting point is from the atmel Linux4SAM project:
Nor layout:
 Logical address: 0xD0000000
   size          Address-Range
   16895 Area 0: D0000000 to D00041FF (RO) Bootstrap
   16895 Area 1: D0004200 to D00083FF      Environment
  236543 Area 2: D0008400 to D0041FFF (RO) U-Boot
 2152687 Area 3: D0042000 to D0251FFF      Kernel
 6217727 Area 4: D0252000 to D083FFFF      FS

Nand layout:

 201226592 0x000004000000-0x000010000000 : "data"

bootargs:
