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>

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.

bool "Enable support for PSCI System Reset"
depends on ARM_PSCI_FW
spl: kconfig: separate sysreset and firmware drivers from misc This adds separate kconfig options for drivers/sysreset and drivers/firmware. Up to now, CONFIG_SPL_DRIVERS_MISC_SUPPORT added drivers/misc to SPL build but also added drivers/firmware and drivers/sysreset at the same time. Since that is confusing, this patch uses CONFIG_SPL_SYSRESET for drivers/sysreset and adds CONFIG_SPL_FIRMWARE for drivers/firmware (and accordingly for the TPL options). CONFIG_SPL_DRIVERS_MISC_SUPPORT stays for including drivers/misc into the SPL build (and accordingly for TPL) since there are boards using non-DM (non UCLASS_MISC) files from drivers/misc. Such boards don't have CONFIG_SPL_MISC enabled, so cannot use this to include drivers/misc into the SPL build. Signed-off-by: Simon Goldschmidt <simon.k.r.goldschmidt@gmail.com>

sysreset: Add TI System Control Interface (TI SCI) sysreset driver Devices from the TI K3 family of SoCs like the AM654x contain a Device Management and Security Controller (SYSFW) that manages the low-level device control (like clocks, resets etc) for the various hardware modules present on the SoC. These device control operations are provided to the host processor OS through a communication protocol called the TI System Control Interface (TI SCI) protocol. This patch adds a system reset driver that communicates to the system controller over the TI SCI protocol for allowing to perform a system- wide SoC reset.
