Linux Kernel def_config difference ....

Hello,

 

Someone knows the difference between the xilinx_zynq_apf_defconfig and xilinx_zynq_defconfig configuration for the Zynq Linuz kernel from Xilinx ?

 

I was checking the config files and I couldn't find much difference except for:

diff -u arch/arm/configs/xilinx_zynq_apf_defconfig arch/arm/configs/xilinx_zynq_defconfig
