Boot flash

[Joakim Tjernlund]

Hi all

I want to use JFFS on a custom made PPC860 board. This board will have NOR
flash memory(Intel) and will probably use ppcboot(suggestions for better
boot loader welcome).
Can I have ppcboot share a flash device with JFFS?

something like this:

  FLASH device 1:
  -------------------------  address 0
  |  ppcboot              |
  |-----------------------|
  |  linux kernel         |
  |-----------------------|
  |  start of JFFS        |
  |                       |
  |                       |
  |                       |
  |                       |
  -------------------------
  FLASH device 2:
  -------------------------
  |   JFFS continued      |
  |                       |
  |                       |
  |                       |
  |                       |
  |                       |
  |                       |
  |                       |
  |                       |
  -------------------------

ppcboot starts after a reset, loads the linux kernel image. The linux kernel
expects to find JFFS at some offset(compiled into JFFS) in the flash device.

Is this possible or do I need an extra boot flash where ppcboot and linux
kernel goes?
