FLASH_CTRL Device Interface Functions

Definition in file dif_flash_ctrl_autogen.h.

Data Structure Documentation

◆ dif_flash_ctrl

struct dif_flash_ctrl

A handle to flash_ctrl.

This type should be treated as opaque by users.

Definition at line 33 of file dif_flash_ctrl_autogen.h.

Data Fields
mmio_region_t	base_addr	The base address for the flash_ctrl hardware registers.

Typedef Documentation

◆ dif_flash_ctrl_irq_enable_snapshot_t

typedef uint32_t dif_flash_ctrl_irq_enable_snapshot_t

A snapshot of the enablement state of the interrupts for this IP.

This is an opaque type, to be used with the dif_flash_ctrl_irq_disable_all() and dif_flash_ctrl_irq_restore_all() functions.

Definition at line 232 of file dif_flash_ctrl_autogen.h.

◆ dif_flash_ctrl_irq_state_snapshot_t

typedef uint32_t dif_flash_ctrl_irq_state_snapshot_t

A snapshot of the state of the interrupts for this IP.

This is an opaque type, to be used with the dif_flash_ctrl_irq_get_state() and dif_flash_ctrl_irq_acknowledge_state() functions.

Definition at line 136 of file dif_flash_ctrl_autogen.h.

◆ dif_flash_ctrl_t

typedef struct dif_flash_ctrl dif_flash_ctrl_t

A handle to flash_ctrl.

This type should be treated as opaque by users.

Enumeration Type Documentation

◆ dif_flash_ctrl_alert

enum dif_flash_ctrl_alert

A flash_ctrl alert type.

Enumerator
kDifFlashCtrlAlertRecovErr	Flash recoverable errors.
kDifFlashCtrlAlertFatalStdErr	Flash standard fatal errors.
kDifFlashCtrlAlertFatalErr	Flash fatal errors including uncorrectable ECC errors. Note that this alert is not always fatal. The underlying error bits in the !!FAULT_STATUS register remain set until reset, meaning the alert keeps firing. This doesn't hold for !!FAULT_STATUS.PHY_RELBL_ERR and !!FAULT_STATUS.PHY_STORAGE_ERR. To enable firmware dealing with multi-bit ECC and ICV errors during firmware selection and verification, these error bits can be cleared. After passing this stage, it is recommended that firmware classifies the corresponding alert as fatal on the receiver end, i.e, inside the alert handler.
kDifFlashCtrlAlertFatalPrimFlashAlert	Fatal alert triggered inside the flash primitive, including fatal TL-UL bus integrity faults of the test interface.
kDifFlashCtrlAlertRecovPrimFlashAlert	Recoverable alert triggered inside the flash primitive.

Definition at line 56 of file dif_flash_ctrl_autogen.h.

◆ dif_flash_ctrl_irq

enum dif_flash_ctrl_irq

A flash_ctrl interrupt request type.

Enumerator
kDifFlashCtrlIrqProgEmpty	Program FIFO empty.
kDifFlashCtrlIrqProgLvl	Program FIFO drained to level.
kDifFlashCtrlIrqRdFull	Read FIFO full.
kDifFlashCtrlIrqRdLvl	Read FIFO filled to level.
kDifFlashCtrlIrqOpDone	Operation complete.
kDifFlashCtrlIrqCorrErr	Correctable error encountered.
