* commands: provide efi_handle_dump in both payload and loaderAhmad Fatoum2024-03-051-0/+2
| | | | | | | | | | | The efi_handle_dump command is currently used when barebox is built as payload, but it's also useful when running as a loader to list handles and their protocols. Move the code into a common area to make it accessible in both configurations.

* commands: add partedSascha Hauer2024-02-201-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds a parted command which behaves pretty much like the GNU parted program. Unlike other partition manipulation programs parted has a quite convenient command line API suitable for scripting. The tool supports these commands: print - print a partition table mklabel - create a new partition table rm - remove a partition mkpart - create a partition unit - change input/display units refresh - refresh a partition table (barebox specific) Multiple commands can be given on a single call so that a full partition table including partitions can be created with a single command. Examples include: Print a partition table: $ parted mmc0 print create a new partition table: $ parted mmc0 mklabel gpt create a new partition table and add a partition beginning at offset 1MiB ending at offset 128MiB: $ parted mmc0 mklabel gpt mkpart rootfs ext4 1MiB 128MiB The same, using KiB as unit and printing the result at the end: $ parted mmc0 unit KiB mklabel gpt mkpart rootfs ext4 1024 131072 print The "refresh" command is barebox specific and is useful when for example the alternate GPT is missing. This happens when an image is written. Link: https://lore.barebox.org/20240219083140.2713047-13-s.hauer@pengutronix.de Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* | commands: implement of_compatible commandAhmad Fatoum2023-05-251-0/+1
|/ | | | | | | | | | | | | | | | | | | | | | Currently, the usual way within scripts to differentiate between machines is to compare global.model or global.hostname. Both are suboptimal, because they may change between releases or overridden by the user. In C code, the machine compatible is used for this purpose. Add a new of_compatible command that makes of_machine_is_compatible/ of_device_is_compatible available to scripts.

* commands: implement devlookup to find device behind device fileAhmad Fatoum2022-07-051-0/+1
| | | | | | | | | | | | | | | | | | | For OF-enabled platforms with aliases, device file naming is pretty much solved: If there is mmc2 = &something, then we have a mmc2 device and a /dev/mmc2 device file. For other platforms like x86, EFI-provided devices are harder to get ahold of. Add a command to make this straight-forward to do in scripts. The main use of this is probably to access parameters like nt_signature or guid: devlookup /dev/disk0 guid This would print to console, but we have no output capture yet, so add an optional -v VARIABLE parameter as well to allow easy use from scripts.

They offer flexibility to test specific units of barebox instead of the program as a whole. Add a very simple infrastructure for registering and executing self-tests. This is based on the Linux kselftest modules. We don't utilize modules for this, however, because we only have module support on ARM, but we need a generic solution. Selftests can be enabled individually and even tested without shell support to allow tests to happen for size-restricted barebox images as well.

* commands: setenv: allow use with hush shellAhmad Fatoum2020-09-181-1/+1
| | | | | | | | | | | | | | | | | | | setenv was so far restricted to the simple shell, because with hush, users could just do dev.var=VAL for setting variables in the environment. The hush syntax doesn't allow for setting all kinds of environment variables though, e.g. 5c00a000.tamp@5c00a000:reboot-mode.of.param can't be set with hush, because of the special characters. It could still be read by using the ${variable} syntax though. Allow setting these variables by making the setenv command generally available. The default is chosen to be 'y', because the command is deemed small and useful enough to have it there by default.

Compared to mmc-utils' mmc enh_area set <-y|-n|-c> <start KiB> <length KiB> <device> the command that is implemented here ( mmc enh_area [-c] <device> ) is easier to use (because you don't have to check the maximal allowed size by reading some registers and calculate the available size from them (which then must be calculated back to register values by the mmc command)) but less flexible as it doesn't allow all the crazy possibilities specified in the eMMC standard (yet?) but just creates an enhanced area with maximal size. In the future something like mmc enh_area -s 30k <device> could be used to not use the maximal but an explicit size.

* boot: add framework for redundant boot scenariosMarc Kleine-Budde2016-09-221-0/+1
| | | | | | | | | | | | | | | There are several use cases where a redundant Linux system is needed. The barebox bootchooser framework provides the building blocks to model different use cases without the need to start from the scratch over and over again. The bootchooser works on abstract boot targets, each with a set of properties and implements an algorithm which selects the highest priority target to boot. See the documentation contained in this patch for more information.

* commands: Create nand_bitflip commandSascha Hauer2016-04-061-0/+1
| | | | | | | | | | | | | | | | | | | This adds a command to flip bits in a Nand flash. This is useful for testing purposes to check if flipped bits are corrected and if the driver returns the correct number of bitflips. The command writes a configurable number of bitflips to a single Nand page. If the -r option is not given the results are reproducible, so calling the same command twice will revert the bitflips. The command uses the raw read/write Nand operations which are probably less tested than the regular read/write operations, so the command may produce surprising results. As of writing the command has been tested with the GPMI Nand driver and the imx-nand driver with fixes posted. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | spd_decode command is used for decoding and printing in human-readable format the information found in memory module SPD EEPROMs. There is the decode-dimms program from i2c-tools linux package (see http://www.lm-sensors.org/wiki/I2CTools) just for the same purpose. Though spd_decode source code is based on decode-dimms perl code there is a difference. Signed-off-by: Alexander Smirnov <alllecs@yandex.ru> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
