	GBL application tag type.

struct	EblBootloader_t
	GBL bootloader tag type.

struct	EblSeUpgrade_t
	GBL SE upgrade tag type.

struct	EblMetadata_t
	GBL metadata tag type.

struct	EblProg_t
	GBL flash program tag type.

struct	EblEnd_t
	GBL end tag type.

struct	EblEncryptionHeader_t
	GBL encryption header tag type.

struct	EblEncryptionInitAesCcm_t
	GBL encryption init tag type. Used with AES-CCM encryption.

struct	EblEncryptionData_t
	GBL encryption data tag type.

struct	EblEncryptionAesCcmSignature_t
	GBL encryption AES-CCM MAC tag type.

struct	EblCertificateEcdsaP256_t
	GBL certificate chain for signing.
