lpc系列FreeRTOS移植

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 three 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. For example, if you are interested in the GCC port for the ATMega323 microcontroller then the port specific files are contained in FreeRTOS/Source/Portable/GCC/ATMega323 directory. If this is the only port you are interested in then all the other directories can be ignored.
