| * restart: replace reset_cpu with registered restart handlersSascha Hauer2015-08-272-8/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This replaces the reset_cpu() function which every SoC or board must provide with registered handlers. This makes it possible to have multiple reset functions for boards which have multiple ways to reset the machine. Also boards which have no way at all to reset the machine no longer have to provide a dummy reset_cpu() function. The problem this solves is that some machines have external PMICs or similar to reset the system which have to be preferred over the internal SoC reset, because the PMIC can reset not only the SoC but also the external devices. To pick the right way to reset a machine each handler has a priority. The default priority is 100 and all currently existing restart handlers are registered with this priority. of_get_restart_priority() allows to retrieve the priority from the device tree which makes it possible for boards to give certain restart handlers a higher priority in order to use this one instead of the default one.

* ARM: MXS: power-init: Add parameters to mx28_power_init()Sascha Hauer2015-02-032-30/+45
| | | | | | | | | | | | | | | | | | | Instead of introducing new functions each time a new power supply situation is to be added, this patch adds parameters to mx28_power_init. Right now there are three parameters: - has_battery - true when this board has a battery. - use_battery_input - true when this board is supplied from the battery input, but has a DC source instead of a real battery - use_5v_input - true when this board can use the 5V input The third one is introduced with this patch and allow to boot a board from 5v (USB) source only. The main necessary change this needs is that the DC-DC converter must always be sourced from DCDC_4P2 (DROPOUT_CTRL field of HW_POWER_DCDC4P2) Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| * ARM: MXS: Add multiimage supportSascha Hauer2015-01-052-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Freescale MXS SoCs have a multi staged boot process which needs different images composed out of different binaries. The ROM executes a so called bootstream which contains multiple executables. The first one is executed in SRAM and the purpose of this binary is to setup the internal PMIC and the SDRAM. The second image is usually the bootloader itself. In case of barebox the bootstream is composed out of the self extracting barebox image (pblx) and the prepare stage for setting up the SDRAM. The bootstream image itself is useful for USB boot, but for booting from SD cards or NAND a BCB header has to be prepended to the image. In case of SD boot the image has the .mxssd file extension in barebox. Since the bootstream images are encrypted they are not suitable for 2nd stage execution. For this purpose the 2nd stage images are generated. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* commands: harmonize in-barebox documentationHolger Schurig2014-05-141-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch does probably too much, but it's hard (and very cumbersome/time consuming) to break it out. What is does is this: * each command has one short description, e.g. "list MUX configuration" * made sure the short descriptions start lowercase * each command has one usage. That string contains just the options, e.g. "[-npn]". It's not part of the long help text. * that is, it doesn't say "[OPTIONS]" anymore, every usable option is listed by character in this (short) option string (the long description is in the long help text, as before) * help texts have been reworked, to make them - sometimes smaller - sometimes describe the options better - more often present themselves in a nicer format * all long help texts are now created with BUSYBOX_CMD_HELP_ macros, no more 'static const __maybe_unused char cmd_foobar_help[]' * made sure the long help texts starts uppercase * because cmdtp->name and cmdtp->opts together provide the new usage, all "Usage: foobar" texts have been removed from the long help texts * BUSYBOX_CMD_HELP_TEXT() provides the trailing newline by itself, this is nicer in the source code * BUSYBOX_CMD_HELP_OPT() provides the trailing newline by itself * made sure no line gets longer than 77 characters * delibertely renamed cmdtp->usage, so that we can get compile-time errors (e.g. in out-of-tree modules that use register_command() * the 'help' command can now always emit the usage, even without compiled long help texts * 'help -v' gives a list of commands with their short description, this is similar like the old "help" command before my patchset * 'help -a' gives out help of all commands Signed-off-by: Holger Schurig <holgerschurig@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
