When testing the sound system we don't need the hear the beeps. The
testing works by checking the data that would be emitted. Add a
device-tree property to silence the sound, and enable it for testing.Signed-off-by: Simon Glass

Some audio codecs such as Intel HDA do not need to use digital data to
play sounds, but instead have a way to emit beeps. Add this interface as
an option. If the beep interface is not supported, then the sound uclass
falls back to the I2S interface.Signed-off-by: Simon Glass

This struct is getting larger and in some cases is being used for things
which would be better put into a driver. For example hwspinlock is not
used outside of sandbox_hwspinlock.c.Add a note to encourage people to put things elsewhere.

The current dev_read...() functions use s32 and u32 which are convenient

The sound driver pulls together the audio codec and i2s drivers in order
to actually make sounds. It supports setup() and play() methods. The
sound_find_codec_i2s() function allows locating the linked codec and i2s
devices. They can be referred to from uclass-private data.Add a uclass and a test for sound.

At present we use a single buffer for sound which means we cannot be
playing one sound while queueing up the next. This wouldn't matter except
that a long sound (more than a second) has to be created as a single
buffer, thus using a lot of memory. To better mimic what real sound
drivers do, add support for double buffering in sandbox.Signed-off-by: Simon Glass

The i2s bus is commonly used with audio codecs. It provides a way to
stream digital data sychronously in both directions. U-Boot only supports
audio output, so this uclass is very simple, with a single tx_data()

At present sandbox has a start.o in the 'start' target but also includes
it in the normal target list. This is not how this is normally handled. It
is needed because sandbox does not include the u-boot-init variable in its

'extras' list.Signed-off-by: Simon Glass

The use of strcpy() to remove characters at the start of a string is safe
in U-Boot, since we know the implementation. But in os.c we are using the
C library's strcpy() function, where this behaviour is not permitted.Update the code to use memmove() instead.

Most architectures use jump_to_image_no_args() to jump from SPL to U-Boot.
At present sandbox is special in that it jumps in its
spl_board_load_image() call. This is not strictly correct, and means that
sandbox misses out some parts of board_init_r(), just as calling
bloblist_finish(), for example.Change spl_board_load_image() to just identify the filename to boot, and
implement jump_to_image_no_args() to actually jump to it.Signed-off-by: Simon Glass

The current method of starting U-Boot from U-Boot adds arguments to pass
the memory file through, so that memory is preserved. This is fine for a
single call, but if we call from TPL -> SPL -> U-Boot the arguments build
up and we have several memory files in the argument list.Adjust the implementation to filter out arguments that we want to replace
with new ones. Also print a useful error if the exec() call fails.Signed-off-by: Simon Glass

At present sandbox calls malloc() from various places in the OS layer and
this results in calls to U-Boot's malloc() implementation. It is better to
use the on in the OS layer, since it does not mix allocations with the
main U-Boot code.Fix this by replacing calls with malloc() to os_malloc(), etc.
