BKM: starting a new BSP

This is a practical 'quick start' on creating a new BSP. For detailed background and instructions on how to to formally do this, please see the BSP Developer's Guide [1] and the Kernel Manual [2]. This document is essentially a pragmatic distillation of those documents but oriented toward the mechanics of quickly getting the initial BSP infrastructure in place for a minimally functional new BSP.

Starting Out

As mentioned in the BSP Developer's Guide, the easiest way to start a new BSP is to base it on a similar already-existing working BSP. For this guide, we'll essentially go through the steps used to create the BSP for the Fish River Island, which exists in its current form as meta-fishriver in the meta-intel repository.
