bool "Enable support for system reset drivers"

help
Enable system reset drivers which can be used to reset the CPU or
board. Each driver can provide a reset method which will be called
to effect a reset. The uclass will try all available drivers when
reset_walk() is called.
sysreset: psci: support system reset in a generic way with PSCI If the system is running PSCI firmware, the System Reset function (func ID: 0x80000009) is supposed to be handled by PSCI, that is, the SoC/board specific reset implementation should be moved to PSCI. U-Boot should call the PSCI service according to the arm-smccc manner. The arm-smccc is supported on ARMv7 or later. Especially, ARMv8 generation SoCs are likely to run ARM Trusted Firmware BL31. In this case, U-Boot is a non-secure world boot loader, so it should not be able to reset the system directly. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

sysreset: Add support for gpio-restart The Linux kernel has binding for gpio-restart node. This patch is adding basic support without supporting any optional properties. This driver was tested on Microblaze system where gpio is connected to SoC reset logic. Output value is handled via gpios cells values. In gpio_reboot_request() set_value is writing 1 because dm_gpio_set_value() is capable to changing it when it is ACTIVE_LOW. ... if (desc->flags & GPIOD_ACTIVE_LOW) value = !value; ...

config SYSRESET_GPIO
bool "Enable support for GPIO reset driver"

help
Reset support via GPIO pin connected reset logic. This is used for
example on Microblaze where reset logic can be controlled via GPIO
pin which triggers cpu reset.
sysreset: Add support for Microblaze soft reset jump Microblaze is storing reset vector at address 0x0. It means soft reset can be done by just jumping to this address. This code was in platform code but sysreset interface is providing enough capabilities to have more options how to reset the system. It can go from gpio reset through watchdog reset till soft reset. The driver has not compatible string because this is cpu specific and DM core is not able to detect compatible string in DT root that's why this driver will be instantiated from platform code by calling device_bind_driver(gd->dm_root, "mb_soft_reset", "reset_soft", NULL); It should be bind as the last reset method to ensure that hw reset is called before this.

sysreset: add syscon-reboot driver Add a new sysreset driver based on linux/drivers/power/reset/syscon-reboot.c, which provides a generic driver for platforms that only require writing a mask to a regmap offset.
