Ohad, > mbox_configured is global and therefore does not support > concurrent usage of multiple mailbox instances. -- Why do you say that it doesn't support concurrent usage of multiple mailbox instances ? If you take example of OMAP4, we have 2 mailbox instances, one talking to DSP and other to Ducati and they should be supported concurrently. If you remove the mbox_configured variable, then the mailbox module would shut down once the first instance calls the omap_mbox_put function.
