* ARM: dts: am335x: Fix pinctrl valuesSascha Hauer2020-11-037-396/+396
| | | | | | | | | | | | Linux 27c90e5e48d0 ("ARM: dts: am33xx-l4: change #pinctrl-cells from 1 to 2") changes #pinctrl-cells from 1 to 2. With this we need three values per pin. the upstream dts files use the AM33XX_PADCONF() macro which handles this change, but the barebox dts files do not use this, so we have to add an additional value. This patch is a purely mechanical version, a more fine grained version would drop the nodes/dts files we duplicated from upstream. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | | | | | | | | | | | For testing barebox-state, it would be nice to have a state pre-configured out-of-the-box. Add one to sandbox.dts. Because the barebox message on an non-configured state can looks quite scary, add an init script that tells the user that all is well.

| | | | | | | | | | | | | | | | | | | | | | | | | | Currently, hostfils without a barebox,filename are assigned a new temporary file on every start. For use of a hostfile syscon for reboot mode or reset source, we will need to persist the changes over a regular reset. This can easily be done by passing through all automatically created temporary file with an explicit --image option on subsequent runs. Do so.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | So far use of hostfile in the device tree required us to hard code a file name. If we instead create a temporary file on demand, we can support: - environment - barebox-state - syscon for reset source and reboot mode out of the box with no dependency on external files. Do the necessary, so a hostfile device tree node without a barebox,filename gets a temporary file generated with the appropriate size.

| * sandbox: hostfile: unify --image and direct device tree probeAhmad Fatoum2020-10-134-40/+90
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 801b7cff0210 ("sandbox: hostfile: allow probing from device tree") added initial support for probing hostfiles out of a non-fixed up device tree. This was achieved by having the driver probe call linux_open if the device tree node doesn't contain a valid barebox,fd property. A mmap did not happen in that case and as such the node couldn't be used as a syscon. Fix this by unifying the binding for hostfiles added by --image and ones already in the device tree. Both will result in a device node with just a barebox,filename property. On pure init level, both kinds of hostfiles will be iterated through and filenames will be opened and mmaped.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | The sandbox architecture is device tree only and so far when no --dtb was passed, it created a basic one itself and used that. Instead of creating the default device tree in C, just build the dtb into barebox like we do on other platforms. When --dtb is specified, that device tree will be used instead.

SRC_GPR9 allows software override of SRC_SBMR1, e.g. to boot via serial download protocol. Define a suitable syscon-reboot-mode node to use it. To have SRC_GPR9 take effect, bit 28 in SRC_GPR10 has to be set as well. To support this, we use the backward-compatible barebox-specific binding for having multiple 32-bit values for a single mode. This node will _not_ be fixed up into the kernel device tree due to the barebox-specific compatible, but as with all reboot mode storage, the referenced locations will be cleared to the normal (here all-zero) mode. User software that expects exclusive access to GPR9 while GPR10 bit 28 is zero will be broken.

The STM32MP1 SoCs have general purpose registers in the TAMP peripheral. Register 20 there is used by the vendor's U-Boot for storing a forced boot mode. We will use the same location for our reboot mode.

| |/ / / / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | add a parameter for the assembly version for passing divisor, and set the default value to DEBUG_LL_UART_ADDR when no parameter is given. Now it is possible to recalculate divisor in runtime to keep the baudrate unchanged. when pll settings changed outside of barebox. e.g. jtag.

| |/ / / | | | | | | | | | | | | | | | | | | | | | | | | | | | | BAREBOX_MAGICVAR now generates a unique identifier automatically, so we can convert users of BAREBOX_MAGICVAR_NAMED to the simpler BAREBOX_MAGICVAR macro. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
