entry
• header: The IVT header has the following format:
• entry: Absolute address of the first instruction to execute from the image.
• reserved1: Reserved and should be zero.
• dcd: Absolute address of the image DCD. The DCD is optional so this field may be set
• boot data: Absolute address of the Boot Data. For i.MX28 this field should be zero.
• self: Absolute address of the IVT. Used internally by the ROM.
• csf: Absolute address of Command Sequence File (CSF) used by the HAB library. See
• reserved2: Reserved and should be zero.
