config XT_WAITI_DELAY
	bool
	default n
	help
	  LX6 Xtensa platforms may require additional delay to flush loads
	  and stores before entering WAITI.

config XT_HAVE_RESET_VECTOR_ROM
	bool
	default n
	help
	  Select if your platform has the reset vector
	  in ROM.

config XT_IRQ_MAP
	bool
	default n

config DMA_HW_LLI
	bool
	default n
	help
	  Hardware linked list is DMA feature, which allows
	  to automatically reload the next programmed linked list
	  item from memory without stopping the transfer. Without
	  it the transfer stops after every lli read and FW needs
	  to manually setup the next transfer.

	  Any platforms with hardware linked list support
	  should set this.

config DMA_SUSPEND_DRAIN
	bool
	default n
	help
	  Some platforms cannot just simple disable DMA
	  channel during the transfer, because it will
	  hang the whole DMA controller. Instead we can
	  suspend the channel and drain the FIFO in order
	  to stop the channel as soon as possible.

	  Any platforms without the ability to disable
	  the DMA channel right away should set this.

config DMA_FIFO_PARTITION
	bool
	default n
	help
	  Some platforms require to manually set DMA
	  FIFO partitions before starting any transfer.

	  Any platforms without automatic FIFO partitions
	  should set this.

config XT_INTERRUPT_LEVEL_1
	bool
	default n
	help
	  Select if the platform supports any interrupts of level 1.
	  Disabling this option allows for less memory consumption.

config XT_INTERRUPT_LEVEL_2
	bool
	default n
	help
	  Select if the platform supports any interrupts of level 2.
	  Disabling this option allows for less memory consumption.

config XT_INTERRUPT_LEVEL_3
	bool
	default n
	help
	  Select if the platform supports any interrupts of level 3.
	  Disabling this option allows for less memory consumption.

config XT_INTERRUPT_LEVEL_4
	bool
	default n
	help
	  Select if the platform supports any interrupts of level 4.
	  Disabling this option allows for less memory consumption.

config XT_INTERRUPT_LEVEL_5
	bool
	default n
	help
	  Select if the platform supports any interrupts of level 5.
	  Disabling this option allows for less memory consumption.
