The FW loader reports and manages exactly two slots: - slot 0: this is the slot for the application code to update - slot 1: this is the slot, in which the FW loader is placed The slot 1 is reported, so tools can fetch metadata about the FW loader installed on the device. Unfortunately, currently SMP-based FW loader allows to issue slot erase command for the slot 1, effectively erasing the FW loader code that is being executed. This change correctly identifies the slot 1 as an active one, marking it as used and blocking erase operation on that slot.
