To install it:

1. Make sure you have at least bootldr-2.10.2

2. 'load kernel', send the zImage

3. 'eflash 0xc80000 0x1380000' to erase the end of the flash

    At this stage, you should see it say something like...
	addr=00C80000
	len=01380000
	Erasing sector 00C80000
	Erasing sector 00CC0000
	Erasing sector 00D00000
	Erasing sector 00D40000
	Erasing sector 00D80000
 	...

    If your bootloader erases only one sector when you give it the above
    command, go back and read step 1 more carefully, or tell it explicitly
    to erase each sector from 0xc80000 to the end of the flash (either 
    0x1000000 or 0x2000000, depending on the size of your flash)

4. 'load flash 0x100000', send jffs2 image

5. 'set linuxargs "noinitrd root=/dev/mtdblock3 init=/linuxrc console=ttySA0"'

6. 'params save'

7. 'boot'
