Allocation of pads during boot-mode..?

[ThomasG1z]

In section 5.2 of e.g. the IMX6DQIEC document for ECSPI1 in the table it seems all ECSPI pads are allocated during boot. Does it mean that if e.g. boot is configured for CS1 that also the CS0, CS2, CS3 pads are allocated, and set to outputs...? Wondering if I can have signals driving unused boot device pads
