8 modules are equipped with a reset signal, typically driven by some
9 reset controller hardware module within the chip. In U-Boot, reset
10 controller drivers allow control over these reset signals. In some
11 cases this API is applicable to chips outside the CPU as well,
12 although driving such reset isgnals using GPIOs may be more
13 appropriate in this case.

73 block, Media I/O block, Peripheral Block.
76 bool "Reset controller driver for AST2500 SoCs"
78 default y if ASPEED_AST2500
80 Support for reset controller on AST2500 SoC.
81 Say Y if you want to control reset signals of different peripherals
82 through System Control Unit (SCU).
85 bool "Reset controller driver for Rockchip SoCs"
86 depends on DM_RESET && ARCH_ROCKCHIP && CLK
89 Support for reset controller on rockchip SoC. The main limitation
90 though is that some reset signals, like I2C or MISC reset multiple
94 bool "Synopsys HSDK Reset Driver"

163 PRCI module within SiFive SoC's provides mechanism to reset
164 different hw blocks like DDR, gemgxl. With this driver we leverage
165 U-Boot's reset framework to reset these hardware blocks.
168 bool "Enable generic syscon reset driver support"
171 Support generic syscon mapped register reset devices.

175 depends on DM_RESET && ARCH_BCM283X
178 Raspberry Pi 4's co-processor controls some of the board's HW
179 initialization process, but it's up to Linux to trigger it when
180 relevant. This driver provides a reset controller capable of
181 interfacing with RPi4's co-processor and model these firmware
182 initialization routines as reset lines.
