* ARM: i.MX8M: convert the machine init to the soc driverMarco Felsch2024-01-291-4/+8
| | | | | | | | | | | | | | | | | | | | | | | | | Convert the i.MX8M machine init code to the previously introduced soc framework. The soc driver was mostly copied from Linux with slightly adaptions for barebox. To the soc driver is called during the postcore_initcall to keep the level aligned with the previous imx_init(). The ocotp clock must keept running else the ARM-SMCCC stuck for calls where the TF-A tries to access the ocotp. A sample output of the new introduced soc0 device: | | barebox@FSL i.MX8MM EVKB:/ devinfo soc0 | Bus: soc | Parameters: | family: Freescale i.MX (type: string) | machine: FSL i.MX8MM EVKB (type: string) | revision: 1.0 (type: string) | serial_number: 15182A09DAB5B3C9 (type: string) | soc_id: i.MX8MM (type: string) Signed-off-by: Marco Felsch <m.felsch@pengutronix.de> Link: https://lore.barebox.org/20240125133856.3792552-2-m.felsch@pengutronix.de Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* ARM: i.MX: Move mach header files to include/mach/imxSascha Hauer2023-03-061-3/+3
| | | | | | | | | | | Currently arch specific headers can be included with #include <mach/xxx.h>. With upcoming multi-arch support this is no longer possible as there won't be a single mach anymore. Move all i.MX specific header files to include/mach/imx/ to prepare for multi-arch support. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* ARM: i.MX: demote reset reason print to debug levelLucas Stach2021-05-031-2/+2
| | | | | | | | | | | | | | The i.MX reset reason is not really helpful on its own, as it needs to be augmented with other information like the watchdog state to get the real system reset reason. As it stands this log is more confusing than answering any questions a user might have. Demote the log to debug level to stop this confusion.

| | | | | | | | | | | | | | | | | | | | Whether reset_source_name() returns the just set reset_source is dependent on probe order and the priorities of prior reset sources in relation to the current one.

| * reset_source: drop reset_source_set_instance()Uwe Kleine-König2019-08-281-3/+1
| | | | | | | | | | | | | | | | | | | | | | | | The semantic of reset_source_set_instance() required a separate call to reset_source_set() (or reset_source_set_priority()) and checked right usage only using the type. Make the set of functions a bit easier to use by dropping reset_source_set_instance() and instead introduce a function that can set all relevant parameters (source, priority and instance) in one go.

* | ARM: i.MX: Do not hang() on unknown SoCsSascha Hauer2019-08-191-1/+1
|/ | | | | | | | | | The generic DT image built with CONFIG_ARCH_IMX has nothing really i.MX specific except that it has support for i.MX features. The DT image could be started with a non i.MX device tree which works as expected. imx_init() panics though when started with a non i.MX device tree. Remove the hang() so that we can just continue.

* ARM: i.MX: When SRSR shows wdog then lookup reset source in wdogSascha Hauer2018-11-161-5/+1
| | | | | | | | | | | | | On i.MX6 when the watchdog has resetted the system then the SRSR register correctly shows that the watchdog has resetted the system. This is not the desired result though, a "reset" in barebox or "reboot" in Linux should result in "RST" as reset source. So instead of making the SRSR register value overwrite the reset source read from the watchdog registers, interpret the SRSR value corresponding to watchdog reset as "lookup details in the watchdog registers".
