6 years agofirmware: Add basic support for TI System Control Interface (TI SCI) protocol

firmware: Add basic support for TI System Control Interface (TI SCI) protocol

Texas Instrument's System Control Interface (TI SCI) message protocol is
used in Texas Instrument's System on Chip (SoC) such as those in the K3
family AM654 SoC to communicate between various compute processors with
a central system controller entity.

The TI SCI message protocol provides support for management of various
hardware entities within the SoC. Add support driver to allow
communication with system controller entity within the SoC using the
mailbox client.

This is mostly derived from the TI SCI driver in Linux located at
drivers/firmware/ti_sci.c.

missed. We can just delete the assignments as the config already has

watchdog: mx25: use the imx_watchdog driver for mx25

The existing imx_watchdog driver is compatible with mx25 chipsets.
Add a WDOG1_BASE_ADDR define for the base address and enable the driver
in watchdog's Makefile.

To use the driver, a board must define CONFIG_IMX_WATCHDOG and
CONFIG_HW_WATCHDOG.

This fixes an issue when booting an mx25 chip via usb/serial. In this
case, the boot rom will always enable the watchdog. If u-boot is running
in interactive mode and the watchdog is not serviced, the system is
rebooted when the watchdog expires.
