menuconfig TIDSPBRIDGE
	tristate "DSP Bridge driver"
	depends on ARCH_OMAP3 && !ARCH_MULTIPLATFORM
	select MAILBOX
	select OMAP2PLUS_MBOX
	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 TIDSPBRIDGE_DVFS
	bool "Enable Bridge Dynamic Voltage and Frequency Scaling (DVFS)"
	depends on TIDSPBRIDGE && OMAP_PM_SRF && CPU_FREQ
	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 TIDSPBRIDGE_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 TIDSPBRIDGE_RECOVERY
	bool "Recovery Support"
	depends on TIDSPBRIDGE
	default y
	help
	  In case of DSP fatal error, BRIDGE driver will try to
	  recover itself.

config TIDSPBRIDGE_CACHE_LINE_CHECK
	bool "Check buffers to be 128 byte aligned"
	depends on TIDSPBRIDGE
	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 TIDSPBRIDGE_NTFY_PWRERR
	bool "Notify power errors"
	depends on TIDSPBRIDGE
	help
	  Enable notifications to registered clients on the event of power error
	  trying to suspend bridge driver. Say Y, to signal this event as a fatal
	  error, this will require a bridge restart to recover.

config TIDSPBRIDGE_BACKTRACE
	bool "Dump backtraces on fatal errors"
	depends on TIDSPBRIDGE
	help
	  Enable useful information to backtrace fatal errors. Say Y if you
	  want to dump information for testing purposes.
