EFI_STATUS EFIAPI NorFlashGetInfo	(	IN UINT8 *	Id,
		IN OUT NOR_FLASH_INFO **	FlashInfo,
		IN BOOLEAN	AllocateForRuntime
	)

Return an allocated copy pool of the NOR flash information structure.

Parameters

[in]	Id	Pointer to an array with JEDEC ID obtained from the NOR flash with READ_ID command (0x9f)
	in	out] FlashInfo Pointer to NOR flash information structure
[in]	AllocateForRuntime	A flag specifying a type of a copy pool allocation (TRUE for runtime, FALSE for normal)

Return values

EFI_SUCCESS	Operation completed successfully
EFI_NOT_FOUND	No matching entry in NOR ID table found
EFI_OUT_OF_RESOURCES	No pool memory available

VOID EFIAPI NorFlashPrintInfo ( IN NOR_FLASH_INFO * Info )

Print NOR flash information basing on data stored in the NOR_FLASH_INFO structure.

Parameters

[in] FlashInfo Pointer to NOR flash information structure
