I think we also need to enable:

CONFIG_ARM_APPENDED_DTB
CONFIG_ARM_ATAG_DTB_COMPAT

because currently we append the dtb to the kernel image(will not do this
after u-boot supports dalmore and we can load the dtb in u-boot cmd), so
we need to make kernel being aware of this.

My experience is after I enabled these 2 configs, kernel starts up normally.
