| * | watchdog: add minimal jz4740 driverAntony Pavlov2014-08-014-40/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Also move reset_cpu() for jz4755 SoC from platform code into the new driver code. At the moment mach-xburst lacks clk support so jz4740 watchdog driver looks like a template. We can improve jz4740 watchdog driver later after adding clk support.

| * | consistently use the same bitops.h fileSascha Hauer2014-07-171-11/+15
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We have many variants of the same bitops.h file. Consistently use the same file for all architectures which completely use the generic bitops versions. Some architectures had static inline versions of functions identically to the generic versions, these are removed and the generic versions are used directly now. Also several architectures depend on the generic find_*_bit functions but didn't have the GENERIC_FIND_NEXT_BIT Kconfig option selected. This is added where needed.

| * | make: build device trees with obj-dtb-y and pbl-dtb-ySascha Hauer2014-08-071-10/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To build an object file from a device tree currently we currently have to add them to the Makefile twice, once to dtb-y and once to obj-y. This patch introduces obj-dtb-y and pbl-dtb-y to directly compile a device tree object file for inclusion in the barebox binary or the pbl respectively. The now unneeded dtb-y targets are removed.

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>

|/ | | | | | | | | | | | | | | | | | | 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'.
