* commands: smc: make command usable when ARM_PSCI is undefinedAhmad Fatoum2019-11-191-1/+1
| | | | | | | | | The smc command can be useful whenever PSCI is used, regardless of whether barebox provides the secure monitor or not. Have it depend on ARM_SMCCC instead. Signed-off-by: Ahmad Fatoum <ahmad@a3f.at> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* ARM: psci: factor out smc command into commands/Ahmad Fatoum2019-11-191-0/+15
| | | | | | | | | | | So far, the smc command was only usable when barebox also provides the secure monitor. It's useful to have it when barebox is a PSCI consumer as well to test whether the secure monitor works. Factor out the code into commands/ in preparation to do so. No functional change.

| | | | | | | | | | | Users might want to generate the password while the target is offline. We don't provide a dedicated host tool for that, but barebox sandbox can be used. Document this possibility. While at it, remove a misplaced single quite and slash in the help text.

This can be handy to find out the differences between the barebox live tree and the one we start the kernel with.

| * | mci: implement command to switch a mmc device to enhanced modeUwe Kleine-König2019-09-121-0/+11
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The command structure allows adding more subcommands and is designed to match the Linux program mmc from the mmc-utils. So later more commands can easily be added if need be. 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/+5
| | | | | | | | | | | | | | | 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.

* commands: Create nand_bitflip commandSascha Hauer2016-04-061-0/+17
| | | | | | | | | | | | | | | | | | | 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>
