Nvidia Tegra devices have individual device "blob" keys.

Nvidia Tegra devices have "linear" adressing.

zero address is the beginning of rom2
Further continuation is written in rom3,
and further rom1

therefore, for nvidia, the data recorded in section 0 of rom1 have an address that is the sum of the length of rom2 and rom3

for example rom2 and rom3 have a size of 4mb (0x400000)
data at the beginning of rom1 for the processor will have an address (0x800000)

Nvidea keys is stored at BCT partition
BCT partittion are placed uasially at rom3 or begin of rom1, depended of size of partitions

it's a example:
