This is somewhat off topic for this list.

You may use Buildroot to generate an initramfs image of your filesystem. You 
may optionally compress the initramfs using gzib, xz, etc.

Alternatively, you may generate a (compressed) initramfs directly as the 
kernel Documentation/filesystems/ramfs-rootfs-initramfs.txt document 
describes.
