需要配置vpif的缓存；
1.vpif capture模式选择，vpif_capture_format值：
; [  a4 C8 t) V5 I& G3 aHDTV：预留
: c2 u% Y/ C5 V  B* G. PSDTV: TL5147
RAW:TL2640
2.（ov2640配置分辨率为640*480 = 640*480*2 = 614400）
vpif_capture.ch0_bufsize=614400
8 w, B7 x; J$ k/ q$ @0 X, p例如：
U-Boot >      setenv optargs  ${optargs} vpif_capture_format=RAW vpif_capture.ch0_bufsize=614400
说明：optargs变量为参数添加变量，主要给需要添加参数传递给内核。
