+Amlogic's SMP-capable SoCs use part of the sram for the bringup of the cores.

+Texas Instruments sysc interconnect target module wrapper binding
+
+Texas Instruments SoCs can have a generic interconnect target module
+hardware for devices connected to various interconnects such as L3
+interconnect (Arteris NoC) and L4 interconnect (Sonics s3220). The sysc
+is mostly used for interaction between module and PRCM. It participates
+in the OCP Disconnect Protocol but other than that is mostly independent
+of the interconnect.
+
+Each interconnect target module can have one or more devices connected to
+it. There is a set of control registers for managing interconnect target
+module clocks, idle modes and interconnect level resets for the module.
+
+These control registers are sprinkled into the unused register address
+space of the first child device IP block managed by the interconnect
+target module and typically are named REVISION, SYSCONFIG and SYSSTATUS.
+
+Required standard properties:
+
+- compatible shall be one of the following generic types:
+
+ "ti,sysc-omap2"
+ "ti,sysc-omap4"
+ "ti,sysc-omap4-simple"
+
+ or one of the following derivative types for hardware
+ needing special workarounds:
+
+ "ti,sysc-omap3430-sr"
+ "ti,sysc-omap3630-sr"
+ "ti,sysc-omap4-sr"
+ "ti,sysc-omap3-sham"
+ "ti,sysc-omap-aes"
+ "ti,sysc-mcasp"
+ "ti,sysc-usb-host-fs"
+
+- reg shall have register areas implemented for the interconnect
+ target module in question such as revision, sysc and syss
+
+- reg-names shall contain the register names implemented for the
+ interconnect target module in question such as
+ "rev, "sysc", and "syss"
+
+- ranges shall contain the interconnect target module IO range
+ available for one or more child device IP blocks managed
+ by the interconnect target module, the ranges may include
+ multiple ranges such as device L4 range for control and
+ parent L3 range for DMA access
+
+Optional properties:
+
+- clocks clock specifier for each name in the clock-names as
+ specified in the binding documentation for ti-clkctrl,
+ typically available for all interconnect targets on TI SoCs
+ based on omap4 except if it's read-only register in hwauto
+ mode as for example omap4 L4_CFG_CLKCTRL
+
+- clock-names should contain at least "fck", and optionally also "ick"
+ depending on the SoC and the interconnect target module
+
+- ti,hwmods optional TI interconnect module name to use legacy
+ hwmod platform data
+
+
+Example: Single instance of MUSB controller on omap4 using interconnect ranges
+using offsets from l4_cfg second segment (0x4a000000 + 0x80000 = 0x4a0ab000):
+
+ target-module@2b000 { /* 0x4a0ab000, ap 84 12.0 */
+ compatible = "ti,sysc-omap2";
+ ti,hwmods = "usb_otg_hs";
+ reg = <0x2b400 0x4>,
+ <0x2b404 0x4>,
+ <0x2b408 0x4>;
+ reg-names = "rev", "sysc", "syss";
+ clocks = <&l3_init_clkctrl OMAP4_USB_OTG_HS_CLKCTRL 0>;
+ clock-names = "fck";
+ #address-cells = <1>;
+ #size-cells = <1>;
+ ranges = <0 0x2b000 0x1000>;
+
+ usb_otg_hs: otg@0 {
+ compatible = "ti,omap4-musb";
+ reg = <0x0 0x7ff>;
+ interrupts = <GIC_SPI 92 IRQ_TYPE_LEVEL_HIGH>,
+ <GIC_SPI 93 IRQ_TYPE_LEVEL_HIGH>;
+ usb-phy = <&usb2_phy>;
+ ...
+ };
+ };
+
+Note that other SoCs, such as am335x can have multipe child devices. On am335x
+there are two MUSB instances, two USB PHY instances, and a single CPPI41 DMA
+instance as children of a single interconnet target module.
