* commands: oftree: kill oftree -fSascha Hauer2018-06-111-16/+1
| | | | | | | | | | Being able to free the live device tree seemed like a good idea in the early days of device tree support when the first boards were brought up. It turned out to be illusory that noone stores pointers to the live tree which become invalid when oftree -f is executed. Enough people stumbled upon crashed boards with this option, so remove it finally. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| * move file helper functions to separate fileSascha Hauer2014-08-071-0/+1
| | | | | | | | | | | | | | | | | | | | We have our file helper functions in several places. Move them all to lib/libfile.c. With this we no longer have file helpers in fs/fs.c which contains the core fs functions and no functions in lib/libbb.c which are not from busybox.

* oftree command: make devicetree file optargs to -l/-sSascha Hauer2014-05-221-38/+16
| | | | | | | | | When loading or saving a devicetree it seems logical to add the filename to the option specifying the command. This is also slightly easier to parse. While at it add missing documentation for the -s option. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* of: Drop devicetree merge supportSascha Hauer2014-05-221-6/+3
| | | | | | | | | | | | I assume I am the only person knowing that barebox is able to merge devicetrees. This feature seems broken for a while now since trying to merge devicetress results in: unflatten: too many end nodes Remove this feature to save the complexity.

* complete: Add devicetree completionSascha Hauer2014-05-191-0/+2

* commands: harmonize in-barebox documentationHolger Schurig2014-05-141-7/+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 ...

* OF: base: rename of_free to of_delete_nodeSebastian Hesselbarth2013-07-051-2/+2
| | | | | | | | | of_free is misleading about the actual purpose of the function. There is already a of_create_node counterpart, so rename of_free to of_create_node and update all users accordingly.

* OF: base: sync of_find_node_by_path with linux OF APISebastian Hesselbarth2013-06-201-10/+1
| | | | | | | | | | | | | Barebox of_find_node_by_path requires a node to be passed as start node to start searching. Linux OF API does not pass this node and no current user of it in barebox is passing anything else than the root node. Therefore, we rename current function to of_find_node_by_path_from and introduce a Linux OF API compatible of_find_node_by_path that always passes the current root_node. Also, all current users of that function are updated to reflect the API change.

* of: let of_unflatten_dtb return the unflattened treeSascha Hauer2013-03-061-1/+13
| | | | | | | | | In order to be able to handle multiple devicetrees, do not assume the tree to be unflattened is the barebox internal one. Instead, just return a pointer to it and assign the barebox internal root_node external to the unflatten function. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* oftree command: refactorSascha Hauer2013-01-191-31/+68
| | | | | | | | | | | | | | | | | | | | | | | | | This has several improvements for the oftree command: - loading a devicetree (-l) and actually probing (-p) it now is separated - the command now can dump the internal devicetree or a dtb given on the command line. - The -f option now actually frees the internal devicetree With this the usage pattern for this command is: oftree -l /env/oftree oftree -d -n /sound oftree -d /env/oftree oftree -f oftree -p oftree -l -p /env/oftree Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* of: remove unused barebox_fdtSascha Hauer2013-01-191-8/+1
| | | | | | | | barebox_fdt should once become the pointer to the barebox internal devicetree. Since barebox has its own internal devicetree format this was never used. remove it. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* of: rename of_parse_dtb to of_unflatten_dtbSascha Hauer2013-01-111-1/+1

* | oftree command: Add devicetree probe supportSascha Hauer2012-09-141-13/+15
|/ | | | | | | | | | With this the -p option is no longer for parse, but for probe instead. Using this parses a devicetree given on the command line and probes the devices found in this tree. Devices which already exist are not probed again, but instead their device_node is attached to the existing device. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* initial oftree command supportSascha Hauer2011-10-191-0/+135
This adds basic device tree command support. So far we can parse a flat device tree (-p), which also stores the tree in memory, dump it (-d) and free (-f) the internally stored tree. The chosen node can be updated with barebox bootargs, no other device tree manipulation is implemented yet. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
