* doc: bcm283x: fix mix up regarding SoC on raspberry pi zeroAhmad Fatoum2020-11-231-2/+2
| | | | | | | | The Raspberry Pi Zero has the same ARMv6 SoC as the very first Raspberry Pi 1, not an ARMv8. Signed-off-by: Ahmad Fatoum <a.fatoum@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* Documentation: state: clarify how to access state device parametersAhmad Fatoum2020-11-131-3/+3
| | | | | | | | | | | | Users may be inclined to use hyphens in state variable names as this is customary for device tree nodes. Such variables can't be read with $state.example-variable or written with state.example-variable=, because it's incompatible with Hush. Adjust the documentation to nudge users into the correct direction (${state.example-variabe} and setenv) Suggested-by: Matthias Fend <Matthias.Fend@wolfvision.net> Signed-off-by: Ahmad Fatoum <a.fatoum@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* doc: add note about characters like hyphens in variable namesAhmad Fatoum2020-11-131-1/+8
| | | | | | | | | | | | | | The mismatch between the allowed characters in shell variables and device parameters is a common pitfall, especially because device tree node names often have hyphens in them, which is disallowed by hush. While such variables can be read by the ${variable-example}, setting them is only possible with the setenv command. Reflect this in the documentation.

| | | | | | | | | | | | | | | | | | | | | | | | The documentation structure is a bit unfortunate because it says 4.1. Aarch64, but lists only a single virtual board. Fix this by: - Removing the Aarch64 heading, as there are more boards outside it - Explicitly note that this documentation page only refers to the virtual target Signed-off-by: Ahmad Fatoum <a.fatoum@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| * defaultenv: provide defaults for generic reboot modesAhmad Fatoum2020-09-291-4/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While reboot mode magic identifiers can be very board specific, we can settle on common names to allow some generic reboot mode handling: - loader -> drop to bootloader shell on next boot - bootloader -> enable fastboot on next boot - recovery -> display barebox boot menu Boot modes loader and bootloader are admittedly a bit ambiguous, but this nomenclature was chosen, because it's already in use on Android and Rockchip systems.

| * power: reset: reboot-mode: port syscon-reboot-mode supportAhmad Fatoum2020-09-291-0/+11
| | | | | | | | | | | | | | | | | | | | Reboot modes are one-shot information that should be valid for only a single reset. Syscons that survive a warm reset are one way to implement this. This is used by many BootROMs to allow falling into a recovery mode on the next boot. This ports the Linux syscon-reboot-mode support.

| * drivers: add reboot-mode infrastructureAhmad Fatoum2020-09-291-0/+84
| | | | | | | | | | | | | | | | | | | | | | Reboot modes provide a well-defined way to exchange information between different stage of the boot process. When configured, users can type `reboot bootloader` in the OS and barebox can read it out a device parameter. Likewise barebox can write a reboot mode for the BootROM to evaluate and then reset to fall into a serial recovery mode for example.

| | | | | | | | | | | | | | | | | | | | | | | | | | There is nothing USB-specific in the defined usbgadget.fastboot_* variables. Rename them to be usable also for the UDP fastboot transport. The usbgadget.fastboot_function variable is used to define the files and devices accessible with the erase and flash commands. Since "function" is a term from the USB specification and the Fastboot specification uses the term "partition", we rename that variable to "fastboot.partitions".
