1.How to use Makefile of directory media:

(1) Compile the entire media directory:
    make  clean
    make

(2) See make configure
    make  info

(3) Clear all compiled files under media directory:
    make  clean

(4) Compile the module singly：
    for example: compile RKAIQ (isp directory)
        (4.1) confirm cfg/cfg.mk configure CONFIG_RK_RKAIQ=y
        (4.2) cd isp; make clean; make

2. Output directory description
