* Refactor linker-generated arraysAlbert ARIBAUD2013-03-12-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | Refactor linker-generated array code so that symbols which were previously linker-generated are now compiler- generated. This causes relocation records of type R_ARM_ABS32 to become R_ARM_RELATIVE, which makes code which uses LGA able to run before relocation as well as after. Note: this affects more than ARM targets, as linker- lists span possibly all target architectures, notably PowerPC.

* sandbox: Add a way of obtaining directory listingsSimon Glass2013-03-04-0/+101
| | | | | | | | 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/+8
| | | | | | | | | | | 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.

* common: Discard the __u_boot_cmd sectionMarek Vasut2012-10-22-3/+0
| | | | | | | | | | | The command declaration now uses the new LG-array method to generate list of commands. Thus the __u_boot_cmd section is now superseded and redundant and therefore can be removed. Also, remove externed symbols associated with this section from include/command.h .

* common: Add .u_boot_list into all linker filesMarek Vasut2012-10-22-0/+5
| | | | | | | | | | Add section for the linker-generated lists into all possible linker files, so that everyone can easily use these lists. This is mostly a mechanical adjustment.

* 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/+190
| | | | | | | | | | | | | | | 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/+5
| | | | | | | | | 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/+60
| | | | | | | | | | | | 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: 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>
