          I2S. It calls either of the two supported codecs (no use is made

+       bool "Enable I2S support for Rockchip SoCs"
+       depends on I2S
+       help
+         Rockchip SoCs support an I2S interface for sending audio data to an
+         audio codec. This option enables support for this, using one of the
+         available audio codec drivers. This driver does not make use of
+         DMA, but writes each word directly to the hardware.

+config I2S_SAMSUNG
+       bool "Enable I2C support for Samsung SoCs"
+       depends on I2S
+       help
+         Samsung Exynos SoCs support an I2S interface for sending audio
+         data to an audio codec. This option enables support for this,
+         using one of the available audio codec drivers. Enabling this
+         option provides an implementation for sound_init() and
+         sound_play().

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

+config SOUND_INTEL_HDA
+       bool "Intel HDA audio codec"
+       depends on SOUND
+       help
+         Most Intel chips have an HDA (High-definition audio) codec which can
+         be used by U-Boot to play simple beeps. This is also sometimes called
+         Azalia which was the development code-name. It requires setup
+         information in the device tree (see intel-hda.txt).
+
+config SOUND_IVYBRIDGE
+       bool "Intel Ivybridge sound support"
+       depends on SOUND
+       select SOUND_INTEL_HDA

+         Enable sound output on supported Intel Ivybridge-based boards. This
+         driver uses Intel's High-definition Audio (HDA) architecture,
+         sometimes called Azalia. The audio codec is detected using a
+         semi-automatic mechanism.

+         Nvidia Tegra SoCs support several I2S interfaces for sending audio
+         data to an audio codec. This option enables support for this,
+         using one of the available audio codec drivers.

+       depends on I2S
+       help
+         Enable the max98088 audio codec. This is connected via I2S for
+         audio data and I2C for codec control. At present it only works
+         with the Samsung I2S driver.
+
+config SOUND_MAX98090

+       depends on SOUND
+       help
+         Enable the Realtek RT5677 audio codec. This is an I2S device used on
+         some Chromebooks from around 2015 ('auron'). It is configured using
+         an I2C interface and supports multiple sound inputs and outputs,
+         including digital microphones.
+
+config SOUND_SANDBOX
+       bool "Support sandbox emulated audio codec"
+       depends on SANDBOX && SOUND
+       help
+         U-Boot sandbox can emulate a sound device using SDL, playing the
+         sound on the host machine. This option implements the sound_init()
+         and sound_play() functions for sandbox. Note that you must install
+         the SDL libraries for this to work.
