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.

+menuconfig TIDSPBRIDGE
+       tristate "DSP Bridge driver"
+       depends on ARCH_OMAP3
+       select OMAP_MBOX_FWK
+       help
+         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).
+
+config BRIDGE_DVFS
+       bool "Enable Bridge Dynamic Voltage and Frequency Scaling (DVFS)"
+       depends on TIDSPBRIDGE && OMAP_PM_SRF && CPU_FREQ
+       default n
+       help
+         DVFS allows DSP Bridge to initiate the operating point change to
+         scale the chip voltage and frequency in order to match the
+         performance and power consumption to the current processing
+         requirements.
+
+config BRIDGE_MEMPOOL_SIZE
+       hex "Physical memory pool size (Byte)"
+       depends on TIDSPBRIDGE
+       default 0x600000
+       help
+         Allocate specified size of memory at booting time to avoid allocation
+         failure under heavy memory fragmentation after some use time.
+
+config BRIDGE_DEBUG
+       bool "DSP Bridge Debug Support"
+       depends on TIDSPBRIDGE
+       help
+         Say Y to enable Bridge debugging capabilities
+
+config BRIDGE_RECOVERY
+       bool "DSP Recovery Support"
+       depends on TIDSPBRIDGE
+       help
+         In case of DSP fatal error, BRIDGE driver will try to
+         recover itself.
+
+config BRIDGE_CACHE_LINE_CHECK
+       bool "Check buffers to be 128 byte aligned"
+       depends on TIDSPBRIDGE
+       default n
+       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.
+
+config BRIDGE_WDT3
+       bool "Enable WDT3 interruptions"
+       depends on TIDSPBRIDGE
+       default n
+       help
+         WTD3 is managed by DSP and once it is enabled, DSP side bridge is in
+         charge of refreshing the timer before overflow, if the DSP hangs MPU
+         will caught the interrupt and try to recover DSP.
+
+config WDT_TIMEOUT
+       int "DSP watchdog timer timeout (in secs)"
+       depends on BRIDGE_WDT3
+       default 5
+       help
+          Watchdog timer timeout value, after that time if the watchdog timer
+          counter is not reset the wdt overflow interrupt will be triggered
+

+
+config BRIDGE_NTFY_PWRERR
+       bool "Notify DSP Power Error"
+       depends on TIDSPBRIDGE
+       help
+         Enable notifications to registered clients on the event of power errror
+         trying to suspend bridge driver. Say Y, to signal this event as a fatal
+         error, this will require a bridge restart to recover.
