2012-03-12sandbox: mark os_exit as noreturnMike Frysinger
Signed-off-by: Mike Frysinger <vapier@gentoo.org>
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>
2012-03-12sandbox: add flags for open() callSimon Glass
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>
2012-03-12sandbox: add lseek helperMike Frysinger
Follow up patches want to be able to seek fd's. Acked-by: Simon Glass <sjg@chromium.org> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2012-03-12sandbox: add ifdef protection to os.hMike Frysinger

2011-12-10sandbox: Add timer simulationMatthias Weisser
Making sleep command work Signed-off-by: Matthias Weisser <weisserm@arcor.de> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-12-10sandbox: Add improved RAM simulationMatthias Weisser
Using mmap to allocate memory from the OS for RAM simulation we can use u-boot own malloc implementation. Tested-by: Simon Glass <sjg@chromium.org> Signed-off-by: Matthias Weisser <weisserm@arcor.de> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-11-03sandbox: put stdin into raw modeMike Frysinger
This allows us to act like a serial device: we get tab chars and CTRL+C and respond appropriately. Signed-off-by: Mike Frysinger <vapier@gentoo.org> Tested-by: Simon Glass <sjg@chromium.org>
2011-10-17sandbox: Add OS dependent layerSimon Glass
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>
