   5 #This class handles all the intricasies of getting the required files from the
   6 #ISE/EDK/project to the kernel and prepare the kernel for compilation.
   7 #The Xilinx EDK supports 2 different architectures : PowerPC (ppc 405,440) and Microblaze
   8 #Only the PowerPC BSP has been tested so far
   9 #For this to work correctly you need to add XILINX_BSP_PATH and XILINX_BOARD to your
  10 #local.conf
  11 #XILINX_BSP_PATH should have the complete path to your project dir
  12 #XILINX_BOARD should have the board type i.e ML403
  13 #
  14 #Currently tested on
  15 #Xilinx ML405
  16 #Xilinx ML507
  17 #More to come soon ;)
