The code for our idle thread looks like this
idle_thread_main:
mov r0, #4096 @ Loop counter
.loop:
nop; nop; nop; nop @ NOP 4 times to waste some cycles
subs r0, #1 @ Decrement counter by 1, go back to looping if loop counter != 0
bne .loop
// Sleep for 0 seconds with the SleepThread SVC, which just yields execution
