= banked register
FIQ mode has seven banked registers mapped to r8–r14 (r8_fiq–r14_fiq).
In ARM state, many FIQ handlers do not have to save any registers.
The User, IRQ, Supervisor, Abort, and undefined modes each have two banked registers
mapped to r13 and r14, allowing a private SP and LR for each mode.
System mode shares the same registers as User mode.
Figure 2-3 shows the ARM-state registers.
