This patch adds BOOTROM_IVT_HDR_OFFSET at 0xC00. The BootROM expects to find the IVT header at a particular offset in an i.MX image.
Defining the expected offset of the IVT header in the first-stage BootROM image format is of use of later stage authentication routines where those routines continue to follow the first-stage authentication layout.
This patch defines the first stage offset with an upcoming set of BSP patches making use of that offset subsequently.
