Fetch Source
Download the Linux kernel source from GitHub by cloning the repository to a local workspace.
$ git clone https://github.com/krtkl/snickerdoodle-linux.git
Build
uImage specifies that the kernel binary be wrapped with a U-Boot header for loading. To build the uImage target, the U-Boot mkimage utility needs to be available via the $PATH variable.
Setup Environment
$ export ARCH=arm CROSS_COMPILE=arm-none-eabi-
Configure Source Tree
$ git snickerdoodle_defconfig
Compile kernel Binary
$ make LOADADDR=0x8000 uImage
