sandbox: Remove all drivers before exit

2014-07-23T13:07:24Z

Drivers are supposed to be able to close down cleanly. To set a good example, make sandbox shut down its driver model drivers and remove them before exit. It may be desirable to do the same more generally once driver model is more widely-used. This could be done during bootm, before U-Boot jumps to the OS. It seems far too early to make this change.

sandbox: Support pre-relocation malloc()

2014-07-23T13:06:13Z

Set up and zero global data before board_init_f() is called so that we can remove the need for CONFIG_SYS_GENERIC_GLOBAL_DATA. Signed-off-by: Simon Glass

sandbox: Set up global data before board_init_f()

2014-07-23T13:05:39Z

At present sandbox defines CONFIG_SYS_GENERIC_GLOBAL_DATA, meaning that the global_data pointer is set up in board_init_f(). If we set up and zero the global data before calling board_init_f() then we don't need to define CONFIG_SYS_GENERIC_GLOBAL_DATA. Make this change to simplify the init process.

sandbox: terminate os_dirent_ls() result list

2014-06-23T21:37:24Z

Each node in the linked-list that os_dirent_ls() returns has its next pointer set only when the next node is created. For the last node in the list, there is no next node, so this never happens, and the next pointer is never initialized. Explicitly initialize the next pointer so that it isn't dangling. Without this, "sb ls" might crash. Signed-off-by: Stephen Warren Acked-by: Simon Glass

sandbox: Add options to clean up temporary files

2014-03-18T02:05:49Z

When jumping from one sandbox U-Boot to another in sandbox, the RAM buffer is preserved in the jump by using a temporary file. Add an option to tell the receiving U-Boot to remove this file when it is no longer needed. Similarly the old U-Boot image is left behind in this case. We cannot delete it immediately since gdb cannot then find its debug symbols. Delete it just before exiting. Together these changes ensure that temporary files are removed both for memory and U-Boot.

sandbox: Allow Ctrl-C to work in sandbox

2014-03-18T02:05:49Z

It is useful for Cltl-C to be handled by U-Boot as it is on other boards. But it is also useful to be able to terminate U-Boot with Ctrl-C. Add an option to enable signals while in raw mode, and make this the default. Add an option to leave the terminal cooked, which is useful for redirecting output. Signed-off-by: Simon Glass

sandbox: Add LCD driver

2014-03-18T02:05:49Z

Add a simple LCD driver which uses SDL to display the image. We update the image regularly, while still providing for reasonable performance. Adjust the common lcd code to support sandbox. For command-line runs we do not want the LCD to be displayed, so add a --show_lcd option to enable it. Tested-by: Che-Liang Chiou Signed-off-by: Simon Glass

sandbox: Add SDL library for LCD, keyboard, audio

2014-03-18T02:05:48Z

SDL (Simple DirectMedia Layer - see www.libsdl.org) is a library which provides simple graphics and sound features. It works under X11 and also with a simple frame buffer interface. It is ideally suited to sandbox U-Boot since it fits nicely with the low-level feature set required by U-Boot. For example, U-Boot has its own font drawing routines, its own keyboard processing and just needs raw sound output. We can use SDL to provide emulation of these basic functions for sandbox. This significantly expands the testing that is possible with sandbox. Add a basic SDL library which we will use in future commits. Tested-by: Che-Liang Chiou Signed-off-by: Simon Glass

sandbox: Add -j option to indicate a jump from a previous U-Boot

2014-03-18T02:05:48Z

In order to support the 'go' command we allow the jumping U-Boot to pass its filename to the new U-Boot image. This can then be used to delete that image if required. Reviewed-by: Simon Glass Tested-by: Che-Liang Chiou Signed-off-by: Simon Glass

sandbox: Add os_jump_to_image() to run another executable

2014-03-18T02:05:48Z

For some tests it is useful to be able to run U-Boot again but pass on the same memory contents. Add a function to achieve this. Reviewed-by: Simon Glass Signed-off-by: Simon Glass
