1.2.1. Boot Flow

The following figure depicts the typical boot flow:

Figure 1. Typical Boot Flow

Additional boot flows are possible, as shown in the following diagram:

Figure 2. Additional Boot Flows

As it can be seen in the above diagram, we always have the Boot ROM, but then we may have more or less stages, depending on the system design.
