i.MX51 LCD类型判断方法

（1）BSP组件中选择了【Device Drivers】->【Display】->【Display Port1】：IPU Support for the ChungHwa WVGA Panle

其定义为：BSP_DISPLAY_CHUNGHWA_CLAA070VC01

（2）Platform.reg中

IF BSP_DISPLAY_CHUNGHWA_CLAA070VC01
; @CESYSGEN IF DIRECTX_MODULES_DIRECTDRAW
[HKEY_LOCAL_MACHINE\Drivers\Display\DDIPU\DI0]
   "PanelType"=dword:5                        ; 5 - ClAA Dumb Panel
   "DualDevice"=dword:1                       ; 1 - TRUE; 0 - FALSE
   "EnableOnBoot"=dword:0                     ; FALSE
   "TVSupported"=dword:0                      ; FALSE
; @CESYSGEN ENDIF DIRECTX_MODULES_DIRECTDRAW
ENDIF BSP_DISPLAY_CHUNGHWA_CLAA070VC01

（3）SRC\DRIVERS\IPUV3\DISPLAY\bspdisplay.cpp中

BOOL BSPGetPanelInfo(DI_SELECT di_sel, PANEL_INFO ** ppInfo)
{
    int panelNum;

   RETAILMSG(DEBUG_MSG, (TEXT("lcd BSPGetPanelInfo !*********!.\r\n")));
    panelNum = GetPanelTypeFromRegistry(di_sel);

    ...

panelNum = panelNum - 1;

...

}

（4）SRC\SOC\COMMON_FSL_V2\IPUV3\DDRAW\ddipu.cpp

BOOL DDIPU::Init(VOID)

{

...

DisplayGetSupportedModes(m_SupportedModes); // 调用了BSPGetPanelInfo

...

}
