FAT support for any microcontroller

[Rahul Sapre] sent us a guide to porting EFSL to any microcontroller (PDF). The Embedded Filesystems Library adds FAT support to C compiled microcontrollers. It is targeted at the AVR line of chips but can be adapted to any architecture that works with a C compiler. [Rahul's] guide will take you through the process of adapting the latest stable 0.2.8 version to new hardware by using a PIC uC as the working example. The non-stable development branch of EFSL is working toward multiple-platform support so consider lending a hand if this interests you.
