ARM RealView Boards
|
||||||
|
-------------------
|
||||||
|
The RealView boards cover tailored evaluation boards that are used to explore
|
||||||
|
the ARM11 and Cortex A-8 and Cortex A-9 processors.
|
||||||
|
|
||||||
|
Required properties (in root node):
|
||||||
|
/* RealView Emulation Baseboard */
|
||||||
|
compatible = "arm,realview-eb";
|
||||||
|
/* RealView Platform Baseboard for ARM1176JZF-S */
|
||||||
|
compatible = "arm,realview-pb1176";
|
||||||
|
/* RealView Platform Baseboard for ARM11 MPCore */
|
||||||
|
compatible = "arm,realview-pb11mp";
|
||||||
|
/* RealView Platform Baseboard for Cortex A-8 */
|
||||||
|
compatible = "arm,realview-pba8";
|
||||||
|
/* RealView Platform Baseboard Explore for Cortex A-9 */
|
||||||
|
compatible = "arm,realview-pbx";
|
||||||
|
|
||||||
|
Required nodes:
|
||||||
|
|
||||||
|
- soc: some node of the RealView platforms must be the SoC
|
||||||
|
node that contain the SoC-specific devices, withe the compatible
|
||||||
|
string set to one of these tuples:
|
||||||
|
"arm,realview-eb-soc", "simple-bus"
|
||||||
|
"arm,realview-pb1176-soc", "simple-bus"
|
||||||
|
"arm,realview-pb11mp-soc", "simple-bus"
|
||||||
|
"arm,realview-pba8-soc", "simple-bus"
|
||||||
|
"arm,realview-pbx-soc", "simple-bus"
|
||||||
|
|
||||||
|
- syscon: some subnode of the RealView SoC node must be a
|
||||||
|
system controller node pointing to the control registers,
|
||||||
|
with the compatible string set to one of these tuples:
|
||||||
|
"arm,realview-eb-syscon", "syscon"
|
||||||
|
"arm,realview-pb1176-syscon", "syscon"
|

"arm,realview-pb11mp-syscon", "syscon"
|
||||||
|
"arm,realview-pba8-syscon", "syscon"
|
||||||
|
"arm,realview-pbx-syscon", "syscon"
|
||||||
|
|
||||||
|
Required properties for the system controller:
|
||||||
|
- regs: the location and size of the system controller registers,
|
||||||
|
one range of 0x1000 bytes.
