2017-12-07Revert "sandbox: remove os_putc() and os_puts()"Simon Glass
While sandbox works OK without the special-case code, it does result in console output being stored in the pre-console buffer while sandbox starts up. If there is a crash or a problem then there is no indication of what is going on. For ease of debugging it seems better to revert this change. This reverts commit 47b98ad0f6779485d0f0c14f337c3eece273eb54. Signed-off-by: Simon Glass <sjg@chromium.org>

2016-07-14sandbox: Allow chaining from SPL to U-Boot properSimon Glass
SPL is expected to load and run U-Boot. This needs to work with sandbox also. Provide a function to locate the U-Boot image, and another to start it. This allows SPL to function on sandbox as it does on other archs. Signed-off-by: Simon Glass <sjg@chromium.org>
2015-06-04sandbox: Tidy up terminal restoreSimon Glass
For some reason 'u-boot -D' does not restore the terminal correctly when the 'reset' command is used. Call the terminal restore function explicitly in this case. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Joe Hershberger <joe.hershberger@ni.com>

2014-03-17sandbox: Allow Ctrl-C to work in sandboxSimon Glass
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 <sjg@chromium.org>
2014-03-17sandbox: Add os_jump_to_image() to run another executableSimon Glass
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 <sjg@chromium.org> Signed-off-by: Simon Glass <sjg@chromium.org>
2014-03-07unit-test: make "test -e" test independent of $CWDStephen Warren
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 <sjg@chromium.org> Signed-off-by: Stephen Warren <swarren@wwwdotorg.org>
2014-01-24sandbox: fix the return type of os_free() functionMasahiro Yamada
The function os_free() returns nothing. Its return type should be "void" rather than "void *". Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
2014-01-08sandbox: Allow reading/writing of RAM bufferSimon Glass
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.

2014-01-08sandbox: Allow the console to work earlierSimon Glass
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.

2013-11-21sandbox: Use uint64_t instead of u64 for timeSimon Glass
The uint64_t type is defined in linux/types.h, so is safer than u64, which is not actually a Linux type. Change-Id: Ifc9a369e6543250c49117b8d3cb3a676eee43e04 Signed-off-by: Simon Glass <sjg@chromium.org>

2013-02-28sandbox: Improve sandbox serial port keyboard interfaceTaylor Hutt
Implements the tstc() interface for the serial driver. Multiplexing the console between the serial port and a keyboard uses a polling method of checking if characters are available; this means that the serial console must be non-blocking when attempting to read characters.

2012-03-12sandbox: add getopt supportSimon Glass
This adds simple command-line parsing to sandbox. The idea is that it sets up the state with options provided, and this state can then be queried later, as needed. New flags are declared with the SB_CMDLINE_OPT_SHORT helper macro, pointers are automatically gathered up in a special section, and then the core code takes care of gathering them up and processing at runtime. This way there is no central place where we have to store a list of flags with ifdefs. Signed-off-by: Simon Glass <sjg@chromium.org> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
