#This class handles all the intricasies of getting the required files from the
#ISE/EDK/project to the kernel and prepare the kernel for compilation.
#The Xilinx EDK supports 2 different architectures : PowerPC (ppc 405,440) and Microblaze
#Only the PowerPC BSP has been tested so far
#For this to work correctly you need to add XILINX_BSP_PATH and XILINX_BOARD to your
#local.conf
#XILINX_BSP_PATH should have the complete path to your project dir
#XILINX_BOARD should have the board type i.e ML403
#
#Currently tested on
#Xilinx ML405
#Xilinx ML507
#More to come soon ;)
