build step:

1. get u-boot source code
   $ wget http://git.freescale.com/git/cgit.cgi/imx/uboot-imx.git/snapshot/rel_imx_3.14.28_1.0.0_ga.tar.bz2
   $ tar -jxvf rel_imx_3.14.28_1.0.0_ga.tar.bz2
   $ cd rel_imx_3.14.28_1.0.0_ga
   $ make make mx6qsabresd_config
   $ make
2. run ./PF_Prj_Gen.sh
   $ ./PF_Prj_Gen.sh u-boot-path output-path
