hmmmm..... I can bring up technexion PICO-PI-IMX7 (lets say FBSD-Things)
with single core mode, need to deal with imx7_mp.c because handling of
imx7-MU is different with bcm2836-MAILBOX, still, kernel will stuck if
don't comment D$-related function in reinit_mmu, maybe need some marco for
Cortex-A7 platform.
