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 -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 facility to save/restore sandbox state

2014-01-09T00:25:08Z

It is often useful to be able to save out the state from a sandbox test run, for analysis or to restore it later to continue a test. Add generic infrastructure for doing this using a device tree binary file. This is a flexible tagged file format which is already supported by U-Boot, and it supports hierarchy if needed.

sandbox: Allow reading/writing of RAM buffer

2014-01-09T00:25:03Z

It is useful to be able to save and restore the RAM contents of sandbox U-Boot either for setting up tests, for later analysys, or for chaining together multiple tests which need to keep the same memory contents. Add a function to provide a memory file for U-Boot. This is read on start-up and written when shutting down. If the file does not exist on start-up, it will be created when shutting down.

sandbox: Add -i option to enter interactive mode

2014-01-09T00:24:53Z

Normally when U-Boot starts with a command (-c option) it quits when the command completes. Normally this is what is requires, since the test is likely complete. Provide an option to jump into the console instead, so that debugging or other tasks may be performed before quitting. Signed-off-by: Simon Glass Signed-off-by: Simon Glass

sandbox: Allow return from board_init_f()

2014-01-09T00:24:38Z

The execution flow becomes easier if we can return from board_init_f() as ARM does. We can control things from start.c instead of having to call back into that file from other places. Signed-off-by: Simon Glass Signed-off-by: Simon Glass

sandbox: Correct help message garbling

2014-01-09T00:24:23Z

The is displayed for options with no argument, and omitted for those with an argument. Swap this around. Signed-off-by: Simon Glass Signed-off-by: Simon Glass

sandbox: Rename sb_cmdline_option to sandbox_cmdline_option

2013-12-09T19:22:02Z

The new name is longer but more clearly related to sandbox. This is in a separate patch within the same series since some comments on the SPI series rely on it. Signed-off-by: Simon Glass Reviewed-by: Hung-ying Tyan
