On STE side, we are working on a mailbox driver which will rely on 
mailbox framework.
However some modifications in current Omap mailbox framework are needed 
to fit STE HW specificities.
- API naming should be generic (replace omap prefix by mailbox)
- message type should be enhanced
- fifo mechanism is linked to Omap maibox, not needed in STE case since 
it relies on cross interrupt + shared memory
I already have modifications I'll send you to see how we can create a 
common and generic mailbox framework.
