Flash protection range registers
SPI Protected Range Registers ( PR0 - PR4) of SPI Configuration Registers (SPIBAR+0x74 - SPIBAR+0x84). Each register has bits that define protected range, plus WP bit, that defines whether write protection is enabled. There's also FLOCKDN bit of HSFS register (SPIBAR+0x04) of SPI Configuration Registers.
