config CARL9170FW_GPIO_INTERRUPT
	def_bool y
	prompt "GPIO Software Interrupt"
	---help---
	 When this option is enabled, the firmware will poll the GPIO
	 registers and reports to the driver whenever the GPIO state
	 has changed from a previous state.

	 Note: This feature is necessary to monitor the WPS button,
	       if you have one on your device, then say Y.

config CARL9170FW_SECURITY_ENGINE
	def_bool y
	prompt "Support Hardware Crypto Engine"
	---help---
	 This options controls if the firmware will allow the driver
	 to program the security engine / CAM through a firmware
	 interface.

	 Say Y. Unless you want to do the en- and decryption for
	 CCMP(AES), TKIP/WEP(RC4) in the application anyway.

config CARL9170FW_RADIO_FUNCTIONS
	def_bool y
	prompt "Enable Firmware-supported Radio/RF functions"
	---help---
	 Some PHY/RF functions (e.g.: AGC and Noise calibration) need
	 to be done in the firmware.

	 Say Y, unless you really don't need the Radio/RF for
	 your project.

	 This (software) queue is used to send any broad-/multi-cast buffered
	 frames after the next DTIM beacon.

	 This feature is required for Accesspoint mode operation.

	 Say Y.

	---help---
	 Advanced printf (very useful for debugging purposes)
	 The formats supported by this implementation are:
		'd' 'u' 'c' 's' 'x' 'X' 'p'.

	 Note: If this option is disabled, the firmware will be only
	       capable of reported _preformated_ string.

	 With this option enabled, the firmware can wake-up
	 suspended hosts... As long as they fully support
	 USB remote wakeup.

	depends on CARL9170FW_BROKEN_FEATURES
	---help---
	 This option conflicts with the application's LED code.
	 Also, it assumes that you have two LEDs, which is not
	 necessarily true.

config CARL9170FW_DEBUG_UART
	def_bool n

	depends on CARL9170FW_BROKEN_FEATURES
	---help---
	 This option allows the firmware to send BUG/ERR/INFO/DBG and
	 hexdumps through the UART _as well_. However, first: you must
	 connect a working logger.

	def_bool y
	prompt "Enable aggressive size optimization"
	---help---
	 This option adds several more optimization compiler flags,
	 which can greatly reduce the firmware size... at the expense
	 of machine-code readability.

	  Say Y. Else the firmware might not fit onto the device!
