2011-12-10sandbox: fix compiling of cpu/os.cAndreas Bießmann
U-boot itself generally builds with -nostdinc. This is because the bootloader needs to be completely standalone. In the sandbox arch though, we need a little bit of code to glue the u-boot world to the host operating system, and we need to be able to access the host libc's headers in order to do so. Currently, we're using -I/usr/include to workaround the global -nostdinc, but that doesn't work for everyone and for all headers. Instead, let's filter out -nostdinc when building the os.c code. Without this patch, some distros hit errors such as: ---8<--- In file included from /usr/include/fcntl.h:27:0, from os.c:22: /usr/include/features.h:323:26: fatal error: bits/predefs.h: No such file or directory --->8--- Signed-off-by: Andreas Bießmann <biessmann@corscience.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 main programSimon Glass
Add a main program so that we can run U-Boot. Signed-off-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>
2011-10-17sandbox: Add cpu filesSimon Glass
This is an initial implementation with all functions defined but not working. The lds file is very simple since we can mostly rely on the linker defaults. Signed-off-by: Simon Glass <sjg@chromium.org>
