				4	bool "Enable sound support"
				5	help
				6	Support making sounds through an audio codec. This is normally a
				7	beep at a chosen frequency for a selected length of time. However
				8	the drivers support playing arbitrary sound samples using a
				9	PCM interface.
				10
				11	Note: At present the sound setup is somewhat tangled up in that the
				12	audio codecs are called from the sound-i2s code. This could be
				13	converted to driver model.

				17	depends on SOUND
				18	help
				19	I2S is a serial bus often used to transmit audio data from the
				20	SoC to the audio codec. This option enables sound support using
				21	I2S. It calls either of the two supported codecs (no use is made
				22	of driver model at present).

				26	depends on I2S
				27	help
				28	Rockchip SoCs support an I2S interface for sending audio data to an
				29	audio codec. This option enables support for this, using one of the
				30	available audio codec drivers. This driver does not make use of
				31	DMA, but writes each word directly to the hardware.

				37	Samsung Exynos SoCs support an I2S interface for sending audio
				38	data to an audio codec. This option enables support for this,

				54	depends on SOUND
				55	help
				56	This enables support for a beeper that uses the i8254 timer chip.
				57	This can emit beeps at a fixed frequency. It is possible to control
				58	the length of the beeps, by turning a beep on, waiting for a period
				59	of time, then turning it off.
				60
				61	This is quite an old feature, called PIT (Programmable Interval
				62	Timer), but is nonetheless still available on modern x86 machines.

				67	help
				68	Most Intel chips have an HDA (High-definition audio) codec which can
				69	be used by U-Boot to play simple beeps. This is also sometimes called
				70	Azalia which was the development code-name. It requires setup
				71	information in the device tree (see intel-hda.txt).
