Specify the kernel make target to build the kernel that you
need.

help
If your ARM system's Linux kernel is configured with the new (3.7+)
multi-architecture support (CONFIG_ARCH_MULTIPLATFORM=y in your
kernel config), then it is necessary to specify a kernel load address
when building the uImage. This should be a hexadecimal string
beginning with 0x, for example: 0x00008000.
If unsure, let this option empty.
config BR2_LINUX_KERNEL_DTS_SUPPORT
bool "Device tree support"
