1 /*
2 * Nordic Semiconductor nRF51 non-volatile memory
3 *
4 * It provides an interface to erase regions in flash memory.
5 * Furthermore it provides the user and factory information registers.
6 *
7 * QEMU interface:
8 * + sysbus MMIO regions 0: NVMC peripheral registers
9 * + sysbus MMIO regions 1: FICR peripheral registers
10 * + sysbus MMIO regions 2: UICR peripheral registers
11 * + flash-size property: flash size in bytes.
12 *
13 * Accuracy of the peripheral model:
14 * + Code regions (MPU configuration) are disregarded.
