* sandbox: fix the return type of os_free() functionMasahiro Yamada2014-01-24-1/+1
| | | | | | | 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>
* sandbox: Allow reading/writing of RAM bufferSimon Glass2014-01-08-0/+16
| | | | | | | | | | | | | 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: Allow the console to work earlierSimon Glass2014-01-08-0/+20
| | | | | | | | | | | | | 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: Improve/augment memory allocation functionsSimon Glass2014-01-08-0/+29
| | | | | | | | | | Implement realloc() and free() for sandbox, by adding a header to each block which contains the block size.

* sandbox: Use uint64_t instead of u64 for timeSimon Glass2013-11-21-1/+3
| | | | | | | | 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>

* sandbox: Add a way of obtaining directory listingsSimon Glass2013-03-04-0/+48
| | | | | | | | This implementation uses opendir()/readdir() to access the directory information and then puts it in a linked list for the caller's use. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Tom Rini <trini@ti.com>
* sandbox: Improve sandbox serial port keyboard interfaceTaylor Hutt2013-02-28-0/+10
| | | | | | | | | | | 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.

* sandbox: add getopt supportSimon Glass2012-03-12-0/+14
| | | | | | | | | | | | | | | 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>
* sandbox: add flags for open() callSimon Glass2012-03-12-6/+11
| | | | | | | | This provides a way for callers to create files for writing. The flags are translated at runtime, for the ones we support. Signed-off-by: Simon Glass <sjg@chromium.org> Signed-off-by: Mike Frysinger <vapier@gentoo.org>

We want to keep all OS-dependent code in once place, with a simple interface to U-Boot. For now, this is that place. Signed-off-by: Simon Glass <sjg@chromium.org>
