I sometimes use 0xEF08A53C to load bootloader from SD card instead of
on-board flash memory such as eMMC.
  https://github.com/linux-rockchip/u-boot-rockchip/blob/u-boot-rk3288/common/cmd_rockusb.c#L893

I don't know any detail about this function.
(above code says "reboot to maskrom", but it should be wrong from my experience)

do you know something about this function? can you handle this too?

Regards,



Have some discussion with the bootloader engineer, the correct magic number to reboot the system to maskrom mode is 0xEF08A53C. I will fix it in next version.
