* main: Avoid unncessary strdup()/free()Simon Glass2014-05-29-4/+2
| | | | | | | It doesn't seem necessary to use memory allocation in this code. The setenv() will make a copy anyway. Signed-off-by: Simon Glass <sjg@chromium.org>
* main: Make the execution path a little clearer in main.cSimon Glass2014-05-29-4/+8
| | | | | | | | | bootdelay_process() never returns in some circumstances, whichs makes the control flow confusing. Change it so that the decision about how to execute the boot command is made in the main_loop() code, so it is easier to follow. Move CLI stuff to cli.c. Signed-off-by: Simon Glass <sjg@chromium.org>
* main: Hide the hush/simple details inside cli.cSimon Glass2014-05-29-14/+2
| | | | | | | Move these details from main (which doesn't care which parser is used) to cli.c where they belong. Signed-off-by: Simon Glass <sjg@chromium.org>
* Simplify the main loopSimon Glass2014-05-29-27/+32
| | | | | | | The main loop is easier to follow if the code is grouped into separate functions. Make this change, so that main_loop() is easier to read. Signed-off-by: Simon Glass <sjg@chromium.org>
* m68k: powerpc: Clean up do_mdm_initSimon Glass2014-05-29-7/+4
| | | | | | | | This code seems unnecessarily complex. We really just need to check the global_data. Now that is it all in one place, and not arch-specific, this is pretty easy. Signed-off-by: Simon Glass <sjg@chromium.org>
* Move command line API into cli.cSimon Glass2014-05-29-93/+0
| | | | | | | We now have a single entry point to the CLI, whether simple or hush. Put this in its own file. Signed-off-by: Simon Glass <sjg@chromium.org>
* Move autoboot code to autoboot.cSimon Glass2014-05-29-364/+2
| | | | | | | The autoboot code is complex and long. It deserves its own file with a simple interface from main.c. Signed-off-by: Simon Glass <sjg@chromium.org>
* Split out simple parser and readline into separate filesSimon Glass2014-05-29-1012/+5
| | | | | | | It doesn't make sense to have the simple parser and the readline code all in main. Split them out into separate files. Signed-off-by: Simon Glass <sjg@chromium.org>
* move CLI prototypes to cli.h and add commentsSimon Glass2014-05-29-0/+1
| | | | | | | Move the CLI prototypes from common.h to cli.h as part of an effort to reduce the size of common.h. Signed-off-by: Simon Glass <sjg@chromium.org>

| | | | | | Hush is a command-line interpreter, so rename it to make that clearer. Signed-off-by: Simon Glass <sjg@chromium.org>
* Make 'run' use run_command_list() instead of run_command()Simon Glass2014-05-09-1/+1
| | | | | | | | In the case where an environment variable spans multiple lines, we should use run_command_list() so that all lines are executed. This shold be backwards compatible with existing behaviour for existing scripts. Signed-off-by: Simon Glass <sjg@chromium.org>
* Start the deprecation process for generic boardSimon Glass2014-04-17-0/+6
| | | | | | | | We should move forward to remove the old board init code. Add a prominent message to encourage maintainers to get started on this work. Signed-off-by: Simon Glass <sjg@chromium.org>

* fdt: allow bootdelay to be specified via device treeStephen Warren2013-06-04-0/+5
| | | | | | | | | | | | | | | | This can be useful to force bootcmd to execute as soon as U-Boot has started. My use-case is: An SoC-specific tool pushes U-Boot into RAM, along with an image to be written to device boot flash, with the DT config property "bootcmd" set to contain a command to write that image to flash. In this scenario, we don't want to allow any stale bootdelay value taken from the current flash content to affect how long it takes before the flashing process starts.

* main: Separate out the two abortboot() functionsSimon Glass2013-06-04-8/+11
| | | | | | | | | | | | | There are two implementations of abortboot(). Turn these into two separate functions, and create a single abortboot() which calls either one or the other. Also it seems that nothing uses abortboot() outside main, so make it static. At this point there is no further use of CONFIG_MENU in main.c.

| | | | | | | | | | This reverts commit 3b73459ea3421e9f8c6c8c62e1d3fe458ca5bc56. In practice it doesn't seem like a good idea to make the the working FDT point to the control FDT. Now that we can access the control FDT using the 'fdt' command, there is no need for this feature. Remove it. Signed-off-by: Simon Glass <sjg@chromium.org>
* CONFIG_BOOTDELAY default should not affect runtimeJoe Hershberger2013-03-12-8/+6
| | | | | | | | | | | Because the code that handles bootdelay is compiled in conditionally based on the default value, you are restricted in the default, regardless of what you want the runtime options to be. Change the source to always check if any default is given so that other values can be selected and used at runtime. Signed-off-by: Joe Hershberger <joe.hershberger@ni.com>

| * fdt: Set kernaddr if fdt indicates a kernel is presentSimon Glass2012-11-12-0/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If kernel-offset is specified in the fdt, set an environment variable so that scripts can access the attached kernel. This can be used by a packaging program to tell U-Boot about a kernel that has been downloaded alongside U-Boot. The value in the fdt is the offset of the kernel from the start of the U-Boot image, so we can find it just by adding CONFIG_SYS_TEXT_BASE. It is then fairly easy to put something like this in the environment variables in the board header file: "if test ${kernaddr} != \"\"; then "\ "echo \"Using bundled kernel\"; "\ "bootm ${kernaddr};" \ "fi; "\ /* rest of boot sequence follows here */ Signed-off-by: Simon Glass <sjg@chromium.org>
| * fdt: Allow device tree to specify secure bootingDoug Anderson2012-11-12-0/+62
| | | | | | | | | | | | | | | | | | | | | | | | | | When secure booting is chosen: * The u-boot shell is never invoked during boot--we just do a simple table lookup to find the command. This means we could even remove the shell parsing from u-boot and still be able to boot. * The boot command can't be interruped. * Failure doesn't cause us to fall back to the shell.

| * fdt: Tell the FDT library where the device tree isGabe Black2012-11-12-0/+8
| | | | | | | | | | | | | | | | | | | | | | This change adds a call to set_working_fdt_addr near the end of u-boot initialization which tells the fdt command/library where the device tree is. This makes it possible to use the fdt command to look at the active device tree since otherwise there would be no way to know what address it was at to set things up manually.

* Allow newlines within command environment varsSimon Glass2012-08-09-3/+3
| | | | | | | | | | | | Any environment variable can hold commands to be executed by the 'run' command. The environment variables preboot, bootcmd and menucmd have special code for triggering execution in certain circumstances. We adjust these calls to use run_command_list() instead of run_command().

| | | | | | | | | Change all files in common/ to use CMD_RET_USAGE instead of calling cmd_usage() directly.
