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

sandbox: dts: Add display and keyboard to sandbox

2014-03-18T02:05:45Z

Add an LCD display and keyboard to the sandbox device tree so that these features can be used. Signed-off-by: Simon Glass

Use a const pointer for map_to_sysmem()

2014-03-18T02:05:45Z

This function does not actually change the pointer contents, so use const so that functions which have a const pointer do not need to cast. Signed-off-by: Simon Glass

unit-test: make "test -e" test independent of $CWD

2014-03-07T15:59:06Z

The unit-test for hush's "test -e" currently relies upon being run in the U-Boot build directory, because it tests for the existence of a file that exists in that directory. Fix this by explicitly creating the file we use for the existence test, and deleting it afterwards so that multiple successive unit-test invocations succeed. This required adding an os.c function to erase files. Reported-by: Simon Glass Signed-off-by: Stephen Warren
