* fix erasing/protecting flashes with unspecified sizeSascha Hauer2016-04-191-1/+1
| | | | | | | | | | | | | | | | | fixes: 81737c1 mtd: Fix erasing of devices >4GiB Several places erased a complete flash partition passing ~0 as count to erase(). With the above commit count to erase was changed from an unsigned type to a signed type, so the (count > f->size - offset) check in erase() no longer triggers and the ~0 count is no longer adjusted to the whole device size. Among other things this results in saveenv failures on NOR flashes. This patch fixes this by introducing an explicit macro for erasing the whole device which is tested for in erase(). All other negative values are rejected. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Reported-by: Giorgio <giorgio.nicole@arcor.de>

* commands: harmonize in-barebox documentationHolger Schurig2014-05-141-12/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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/+3
| | | | | | | | | | | | | | | | | | | 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 ...

* command: flash: remove broken filename checkWolfram Sang2011-12-221-10/+0
| | | | | | | | | It makes no sense to check the filename pointer here, because a) we have already been using it and b) argc has been tested against 1 already, so argv[1] should not be NULL. So, drop the checks. Signed-off-by: Wolfram Sang <w.sang@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
