From "Anna, Suman" <s-anna@ti.com>:

some coprocessors. This series creates a consolidated framework, living
under drivers/mailbox.

The changes mainly contain:
- create a mailbox framework independent from OMAP h/w
- creates dbx500 mailbox driver for ST-Ericsson platforms
- move the omap mailbox out of plat-omap/mach-omapX  adapting to the new framework.
- minor bug fixes in mailbox code
