sandbox: Correct SDL build flags

2019-01-15T00:47:13Z

The check for CONFIG_SANDBOX_SDL in config.mk does not work since the build config is not available by the time that file is included. Remove it so that we always call sdl-config except when NO_SDL is used. Signed-off-by: Simon Glass

dm: sandbox: Allow selection of sample rate and channels

2018-12-13T23:37:09Z

At present these parameters are hard-coded in the sdl interface code. Allow them to be specified by the driver instead. Signed-off-by: Simon Glass

dm: sound: Complete migration to driver model

2018-12-13T23:36:41Z

All users of sound are converted to use driver model. Drop the old code and the CONFIG_DM_SOUND option. Signed-off-by: Simon Glass

dm: sandbox: sound: Convert to use driver model

2018-12-13T23:36:30Z

Update sandbox's device tree and config to use driver model for sound. Use the double buffer for sound output so that we don't need to wait for the sound to complete before returning. Signed-off-by: Simon Glass

dm: sandbox: Update sound to use two buffers

2018-12-13T23:32:49Z

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

sandbox: Use 'extras' to specify 'head' files

2018-12-05T13:01:34Z

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 link rule. Update the rule and move start.o from the normal target list to the 'extras' list. Signed-off-by: Simon Glass

sandbox: Zero the ram buffer on startup

2018-12-05T13:01:34Z

At present the RAM buffer is not inited unless it is read from a file, likely produced by an earlier phase of U-Boot. This causes valgrind warnings whenever the RAM buffer is used. Correct this by initing it if needed. Signed-off-by: Simon Glass

sandbox: Check the filename in jump_to_image_no_args()

2018-12-05T13:01:34Z

If the filename is NULL this function currently crashes. Update it to fail gracefully. Signed-off-by: Simon Glass

sandbox: Fix up the debug message for the image filename

2018-12-05T13:01:34Z

This currently prints out the wrong filename. Fix it. Signed-off-by: Simon Glass

sandbox: Use memmove() to move overlapping regions

2018-11-29T16:30:05Z

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.
