* global_data: unify global flag definesMike Frysinger2012-08-09-13/+1
| | | | | | | All the global flag defines are the same across all arches. So unify them in one place, and add a simple way for arches to extend for their needs. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* net: punt bd->bi_ip_addrMike Frysinger2012-05-15-4/+0
| | | | | | | | | This field gets read in one place (by "bdinfo"), and we can replace that with getenv("ipaddr"). After all, the bi_ip_addr field is kept up-to-date implicitly with the value of the ipaddr env var.

* sandbox: Use the new run_command()Simon Glass2012-04-23-6/+0
| | | | | | | | Now that run_command() handles both parsers, clean up sandbox to use it. This fixes a build error. Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Mike Frysinger <vapier@gentoo.org>
* sandbox: add getopt supportSimon Glass2012-03-12-0/+290
| | | | | | | | | | | | | | | 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: allow processing before main loopSimon Glass2012-03-12-0/+10
| | | | | | | | | In order to pass command line arguments to sandbox we need to be able to act on them. So take control back at the end of board_init_r() from where we can call the main loop or do something else.

* sandbox: add concept of sandbox stateSimon Glass2012-03-12-2/+117
| | | | | | | | | | | | The state exists through the life of U-Boot. It can be adjusted by command line options and perhaps later through a config file. It is available to U-Boot through state_...() calls (within sandbox code). The primary purpose of this is to contain the "hardware" state. It should only be used by sandbox internal code.

* sandbox: disable fortificationMike Frysinger2012-03-12-1/+1
| | | | | | | | Since we provide all our own library calls, the fortification from glibc just gets in our way (which some distros enable by default). Acked-by: Simon Glass <sjg@chromium.org> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* sandbox: u-boot.lds: tweak styleMike Frysinger2012-03-12-5/+5

* sandbox: gpio: add basic driver for simulating GPIOsSimon Glass2012-03-12-0/+81
| | | | | | | | This provides a way of simulating GPIOs by setting values which are seen by the normal gpio_get/set_value() calls. Signed-off-by: Simon Glass <sjg@chromium.org> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* sandbox: add flags for open() callSimon Glass2012-03-12-2/+22
| | | | | | | | 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>
* sandbox: fdt: add support for CONFIG_OF_CONTROLSimon Glass2012-03-12-0/+9

* sandbox: fix compiling of cpu/os.cAndreas Bießmann2011-12-10-3/+4
| | | | | | | | | | | | | | | | | | | | | | | 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>

* sandbox: Add main programSimon Glass2011-10-17-1/+34

* sandbox: Add OS dependent layerSimon Glass2011-10-17-5/+62
| | | | | | | 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>
* sandbox: Add architecture lib filesSimon Glass2011-10-17-0/+366
| | | | | | | | | | These files are taken from the ARM board implementation and then reduced to remove unneeded cruft. Ideally we would work towards unifying arch/xxx/lib files, particularly board.c. Signed-off-by: Simon Glass <sjg@chromium.org>
* sandbox: Add cpu filesSimon Glass2011-10-17-0/+164
| | | | | | | | 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>

* sandbox: Add architecture header filesSimon Glass2011-10-17-0/+683
This adds required header files for the sandbox architecture, and a basic description of what sandbox is (README.sandbox). Signed-off-by: Simon Glass <sjg@chromium.org>
