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 the console to work earlier

2014-01-09T00:24:50Z

With sandbox, errors and problems may be reported before console_init_f() is executed. For example, an argument may not parse correctly or U-Boot may panic(). At present this output is swallowed so there is no indication what is going wrong. Adjust the console to deal with a very early sandbox setup, by detecting that there is no global_data yet, and calling os functions in that case.

sandbox: Implement the bootm command for sandbox

2014-01-09T00:24:42Z

When sandbox does a 'bootm' to run a kernel we cannot actually execute it. So just exit sandbox, which is essentially what U-Boot does on other archs. Also, allow sandbox to use bootm on any kernel, so that it can be used to test booting of kernels from any architecture. 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: Improve/augment memory allocation functions

2014-01-09T00:24:19Z

Implement realloc() and free() for sandbox, by adding a header to each block which contains the block size. Signed-off-by: Simon Glass Signed-off-by: Simon Glass Reviewed-by: Che-Liang Chiou Reviewed-by: Hung-ying Tyan

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

sandbox: Use system headers first for sandbox's os.c

2013-11-21T23:54:26Z

This file must be compiled with system headers, even if U-Boot has headers of the same name. The existing solution for this is good enough for libfdt, but fails when we have headers like stdint.h in U-Boot. Use -idirafter instead of -I, and remove the -nostdinc and other things that we don't want for this file. The best way to do this is to keep a copy of the original flags, rather than trying to filter them later. Signed-off-by: Simon Glass
