There are different blobs for each PRAM section.
In addition, each blob write operation is divided into a few operations
in order to decrease the amount of phys. contiguous buffer needed.
Thus, when we select a blob the address may be with some offset
from the beginning of PRAM section.
The same holds for the INT_TABLE sections.
