In linux kernel since version 2.6.36 (release Date: 2010-10-20)  
DSP/BIOS Bridge is designed for platforms that contain a GPP and
one or more attached DSPs. The GPP is considered the master or
"host" processor, and the attached DSPs are processing resources
that can be utilized by applications and drivers running on the GPP.

This driver depends on OMAP Mailbox (OMAP_MBOX_FWK).
