高通平臺 lcd 分辨滷更改
1. 更改解析度 需要修改兩部分:
lk部分程式碼：
static struct panel_config adv7533_720p_video_panel_data = {
"qcom,mdss_dsi_adv7533_720p", "dsi:0:", "qcom,mdss-dsi-panel",
- 10, 0, "DISPLAY_1", 0, 0, 60, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, "NONE"
+ 10, 0, "DISPLAY_1", 0, 0, 60, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, NULL
};
bootloader/lk/dev/gcdb/display/include/panel_adv7533_720p60.h
開始發現不好用改完，需要把上邊的 "none" 改為 NULL
標頭檔案，是這個LCD的配置，我這裡是一個AD7535轉換晶片，裡邊都是相關的配置和引數

紅色部分新增相應的設定資料
-------------
msm8976 開機的預設圖片儲存在一個數組裡，
這個資料在drivers/video/msm/mdss/splash.h 檔案裡
此外要替換成自己的圖片可以 用img2lcd4.0 工具轉換成 陣列，轉換的圖片我用的是PNG的，輸出為24bit。
好要修改標頭檔案裡的寬和高 ，和自己的圖片對應上，
要注意一點不要太大，不然不能開機
