I always make my Wandboard Quad board Device Tree and Driver files configurations and changes a from fsl-community-bsp/build/tmp/work/wandboard-poky-linux-gnueabi/linux-wandboard/3.14.28-r0/ directory but I wonder why at the /fsl-community-bsp/build/tmp/work/wandboard-poky-linux-gnueabi directory there is also /fsl-community-bsp/build/tmp/work/wandboard-poky-linux-gnueabi/linux-imx directory. I know that Wandboard has a imx6q processor on it. I think that we are using the linux-wandboard directory for company specific board, and making imx6q dependent changes in the linux-imx/ directory . But kernel versions differs at in both directories ( linux-wandboard/ and linux-imx/ directories) . So I got confused, why the both directory is included in the /fsl-community-bsp/build/tmp/work/wandboard-poky-linux-gnueabi directory.
