| Flash device on ARM Versatile board | |
| These flash chips are found in the ARM reference designs like Integrator, | |
| Versatile, RealView, Versatile Express etc. | |
| They are regular CFI compatible (Intel or AMD extended) flash chips with | |
| some special write protect/VPP bits that can be controlled by the machine's | |
| system controller. | |
| Required properties: | |
| - compatible : must be "arm,versatile-flash", "cfi-flash"; | |
| - reg : memory address for the flash chip | |
| - bank-width : width in bytes of flash interface. | |
| For the rest of the properties, see mtd-physmap.txt. | |
| The device tree may optionally contain sub-nodes describing partitions of the | |
| address space. See partition.txt for more detail. | |
| Example: | |
| flash@34000000 { | |
| compatible = "arm,versatile-flash", "cfi-flash"; | |
| reg = <0x34000000 0x4000000>; | |
| bank-width = <4>; | |
| }; |
