Hi ,

   See here , please!

/* mach-imx6q.c */

DT_MACHINE_START(IMX6Q, "Freescale i.MX6 Quad/DualLite (Device Tree)")
    /*
     * i.MX6Q/DL maps system memory at 0x10000000 (offset 256MiB), and
     * GPU has a limit on physical address that it accesses, which must
     * be below 2GiB.
     */
    .dma_zone_size    = (SZ_2G - SZ_256M),
    .smp        = smp_ops(imx_smp_ops),
    .map_io        = imx6q_map_io,
    .init_irq    = imx6q_init_irq,
    .init_time    = imx6q_timer_init,
    .init_machine    = imx6q_init_machine,
    .init_late      = imx6q_init_late,
    .dt_compat    = imx6q_dt_compat,
    .restart    = mxc_restart,
MACHINE_END
 

and mxc_restart() is in arch/arm/kernel/system.c

Have a nice day!

Hi Sun,

I know that.

4.1.15 bsp never use mxc_restart.
