Each real time kernel port consists of three files that contain the core kernel
components and are common to every port, and one or more files that are
specific to a particular microcontroller and/or compiler.
+ The FreeRTOS/Source/Portable/MemMang directory contains the five sample
memory allocators as described on the http://www.FreeRTOS.org WEB site.
+ The other directories each contain files specific to a particular
microcontroller or compiler, where the directory name denotes the compiler
specific files the directory contains.
For example, if you are interested in the [compiler] port for the [architecture]
microcontroller, then the port specific files are contained in
FreeRTOS/Source/Portable/[compiler]/[architecture] directory. If this is the
only port you are interested in then all the other directories can be
ignored.
