Ok.

We can analyze the requirement for having such structure, presumably
you expect variable size messages, in OMAP case it is a 4 byte value,
but I'm open to change in order to accommodate other users needs.

I agree with the file split but I think mailbox framework API should be
more generic.
omap_ prefix should not be used. mailbox_ prefix will be better.
Message type must be more opened like for example:
struct mailbox_msg {
int size;
unsigned char header;
unsigned char *pdata;
};
