| 13 | The ARM Versatile boards are two variants of ARM926EJ-S evaluation boards |
| 14 | with various pluggable interface boards, in essence the Versatile PB version |
| 15 | is a superset of the Versatile AB version. |
| 16 | |
| 17 | The root node in the Versatile platforms must contain a core module child |
| 18 | node. They are always at physical address 0x10000000 in all the Versatile |
| 19 | variants. |
| 20 | |
| 21 | When fitted with the IB2 Interface Board, the Versatile AB will present an |
| 22 | optional system controller node which controls the extra peripherals on the |
| 23 | interface board. |

| 32 | to an IB1 interface board for a touchscreen-type use case or an IB2 |
| 33 | for a candybar phone-type use case. See ARM DUI 0225D. |
