* ARM: Remove do_execute and thumb2_executeTrent Piepho2015-12-071-4/+1
| | | | | | | | | | | | | | | | | | | | In commit 104a6a7ccfb7928ca5dc28c8cbe0ea231ffc45ee support was added for Thumb2. It added do_execute() as a way to provide arch dependent calling veneers for use in "go" and thumb2_execute() as the thumb2 to arm veneer. But thumb2_execute() isn't necessary as gcc generates a proper calling sequence from a standard function pointer call. Thumb2 barebox is compiled with the AAPCS ABI which requires this. It also had a bug and didn't pass the arguments properly, but code execute via "go" rarely uses arguments so this wasn't very noticeable. Since thumb2 was always the only user of do_execute(), go ahead and delete that too. Signed-off-by: Trent Piepho <tpiepho@kymetacorp.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* commands: harmonize in-barebox documentationHolger Schurig2014-05-141-6/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
* commands: group 'help' outputHolger Schurig2014-05-141-0/+1
| | | | | | | | | | | | | | | | | | | The old output of "help" was just producing a long list, that usually scrolled of the screen (even on a X11 terminal). This list is more compact, and also sorted by groups. The old output format (plus grouping) is now available with 'help -v'. Example: Information commands: ?, devinfo, help, iomem, meminfo, version Boot commands: boot, bootm, go, loadb, loads, loadx, loady, saves, uimage ...

| * ARM: Allow to compile in thumb-2 modeSascha Hauer2012-03-061-1/+5
| | | | | | | | | | | | | | | | | | This shrinks the resulting binary size by ~25%. Exceptions are still handled in arm mode, so we have to explicitely put .arm directives into the exception code. Thumb-2 mode has been tested on i.MX51 Babbage board. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
