How to add an expansion board on IGEP v2 board.

How to add an expansion board on IGEP v2 board.

[Enric Balletbò i Serra]

Hello all,

I would ask some technical questions, maybe someone can help me. I
would add support for a new expansion board for IGEP v2 board,

The expansion board comes with a EEPROM, the EEPROM is used to
identify the expansion board, my idea is create a new file for
expansion board ( board-igep0020-expansion.c ) and

* on board-igep0020.c
  - Add extern void __init igep2_expansion_init(void);
  - Call igep2_expansion_init on igep2_init()

* on board-igep0020-expansion.c
  - Create  igep2_expansion_init, inside this funciton
    - Add e2prom device and read board id
    - If board ID exists then init all expansion devices

I'm in the right way ? Comments ?

Thanks in advance,
   Enric

Sounds good to me. Runtime detection is the best way to go.
