staging: ti dspbridge: enable driver building
Add Kconfig + Makefile for TI's DSP Bridge driver and expose it to the staging menu. For now, have tidspbridge depend on ARCH_OMAP3. That dependency should be relaxed as soon as required cleanups are applied.

|

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).

DVFS allows DSP Bridge to initiate the operating point change to

requirements.

|

help
|
||||
When the DSP processes data, the DSP cache controller loads 128-Byte
|
||||
chunks (lines) from SDRAM and writes the data back in 128-Byte chunks.
|
||||
If a DMM buffer does not start and end on a 128-Byte boundary, the data
|
||||
preceding the start address (SA) from the 128-Byte boundary to the SA
|
||||
and the data at addresses trailing the end address (EA) from the EA to
|
||||
the next 128-Byte boundary will be loaded and written back as well.
|
||||
This can lead to heap corruption. Say Y, to enforce the check for 128
|
||||
byte alignment, buffers failing this check will be rejected.
