Introduction
The Raspberry Pi 2 Model B is the second generation Raspberry Pi based on a Broadcom BCM2836 SoC, with a quad-core ARM Cortex-A7 CPU

Installation
To begin installation, we need to setup an SD card for use with the raspberrypi2.
We will need at least 2 partitions, a fat32 boot partition and a root filesystem partition.
The fat32 boot partition must be first.
If the root filesystem partition is not the second partition, then the root must be specified in the cmdline.txt file.
The root filesystem type must be supported by kernel builtin driver or be provided for via initramfs.
You will need to download the firmware files from upstream RaspberryPi Foundation:
https://github.com/raspberrypi/firmware/raw/master/boot/bootcode.bin
https://github.com/raspberrypi/firmware/raw/master/boot/start.elf
https://github.com/raspberrypi/firmware/raw/master/boot/fixup.dat
Next, we need to download the kernel image, modules, and device tree files:
http://stygian.me/crux-arm/distfiles/kernel7-4.5.4.img
http://stygian.me/crux-arm/distfiles/modules-4.5.4-tar.xz
http://stygian.me/crux-arm/distfiles/dtb-4.5.4-tar.xz
http://stygian.me/crux-arm/distfiles/cmdline.txt
http://stygian.me/crux-arm/distfiles/config.txt
Last, we need to download a root filesystem:
http://resources.crux-arm.nu/releases/3.2/crux-arm-rootfs-3.2-raspberrypi2.tar.xz
Copy bootcode.bin, start.elf, fixup.dat, kernel image (kernel7-*.img), config.txt, and cmdline.txt to the boot partition.
Untar the dtb tarball on to the boot partition.
Untar the modules and rootfs tarballs on to the root filesystem partition.
The boot config.txt and cmdline.txt are our bootloader configuration files.
Documentation for config.txt can be found at https://www.raspberrypi.org/documentation/configuration/config-txt.md .
The linked config.txt is set up for booting with the new opensource vc4 gpu driver.
Documentation for cmdline.txt can be found at http://elinux.org/RPi_cmdline.txt .
Make sure that the root= and rootfstype= parts match the partition and filesystem type of your root partition.
Configuration
We should setup all the important files: pkgmk.conf, prt-get.conf, inittab, fstab, rc.conf, net ...
