Enumeration for NPCX flash extended operations.

Enumerator
FLASH_NPCX_EX_OP_EXEC_UMA	User Mode Access (UMA) mode execution. Execute a SPI transaction via User Mode Access (UMA) mode. Users can perform a customized SPI transaction to read or write the device's configuration such as status registers of nor flash, power on/off, and so on. Parameters in Pointer to a npcx_ex_ops_uma_in structure specifying the UMA transaction. out Pointer to a npcx_ex_ops_uma_out structure to store the result of the UMA transaction.
FLASH_NPCX_EX_OP_SET_QSPI_OPER	Configure specific operation for Quad-SPI nor flash. It configures specific operation for Quad-SPI nor flash such as lock or unlock UMA mode, set write protection pin of internal flash, and so on. Parameters in Pointer to a npcx_ex_ops_qspi_oper_in structure specifying the operation to set.
FLASH_NPCX_EX_OP_GET_QSPI_OPER	Get specific operation for Quad-SPI nor flash. It returns current specific operation for Quad-SPI nor flash. Parameters out Pointer to a npcx_ex_ops_qspi_oper_out structure to store the result of the operation.
