增加暗碼命令切換開關(guān)機logo功能


u-boot logo顯示原理：
1.————Little Kernel會在platform_early_init階段首先會獲取lcm params，其工作流
程就是透過讀id找到現(xiàn)在插入的LCM，根據(jù)LCM的分辨率申請相應(yīng)大小的frame buffer
并確定frame buffer起始地址
2. 為logo.bin預(yù)留4M Ram
3. 之后在platform_init階段，直接將logo.bin載入到4M Ram中
4, 完成載入后，在platform_init中mt_disp_show_boot_logo();會調(diào)用
show_logo(0);完成第一張logo顯示。其中的index=0代表在logo.bin中壓縮的第一張
圖片，logo.bin中的圖片壓縮順序可以察看文件
mediatek\custom\common\lk\logo\rules.mk


2.————4.2的kernel logo顯示原理：
Kernel logo的工作方式與U-boot logo不同，是透過init.rc中注冊的
boot_logo_updater service完成讀取raw data文件，進行繪畫的，所以在kernel
logo只是經(jīng)過了bmp向raw的轉(zhuǎn)換，在目錄mediatek\custom\common\lk\logo\下生成
raw data 文件boot_logo。之后透過腳本文件將boot_logo文件搬移到
out\target\product\xxxx\system\media\images下，打包為system.img，download
到手機種，并存放于/system/media/images目錄下。


3.————4.2對于ipo快速開機，請在目錄mediatek\external\ipod\bootlogo.cpp中的
mt65xx_disp_show_boot_logo();做相應(yīng)修改


4.————4.4的kernel logo和ipo快速開機用的是同一個接口。
在boot_logo_updater.c的main中與4.2的方法不同使用了show_kernel_logo函數(shù)調(diào)用
顯示了包在logo.bin中的kernel.logo，修改方法可以在alps\mediatek\external\libshowlogo\charging_animation.cpp
中對這部分代碼進行嘗試讀取nv顯示修改，kernel層的logoindex可以查看文件
mediatek\custom\common\lk\logo\rules.mk中kernel.bmp的順序
void show_kernel_logo()
{
? ? LOG_ANIM("[charging_animation: %s %d]show kernel logo, index = 38 \n",__FUNCTION__,__LINE__);
? ? if (error_flag == 0)?
? ? {
? ? ? ? anim_show_logo(kernel_logo_position);?
? ? } ? ?
} ? ?
由于快速開關(guān)機部分alps\mediatek\external\ipod\bootlogo.cpp
也是使用了此接口，若添加，應(yīng)該就可以做到暗碼修改了。


對于U-boot logo，只需要將不同分辨率的圖片壓縮至logo.bin中，在讀取時根據(jù)不
同的NVflag顯示相應(yīng)的圖片即可
而對于Kernel logo，我們需要將不同分辨率的boot_logo raw data文件生成出來并
copy到手機中，boot_logo_updater根據(jù)不同的分辨率進行識別，讀取相應(yīng)的logo文
件。在boot_logo_updater識別部分對NVflag進行判斷，進而調(diào)用不同的boot_logo。






一、主要修改文件：
1.mediatek/external.git
boot_logo_custom這部分代碼在4.4上是沒有編譯的，所以不用增加這部分的編譯機制
這部分的logo是動畫之前的那個logo,可以使用adb shell，cd 到/system/bin，執(zhí)行
boot_logo_updater查看這個logo具體是哪張圖片

A packages/apps/Contacts/src/com/mediatek/contacts/NvRAMAgent.java
這個文件是生成出來的，可以不用增加
packages/apps/Contacts/src/com/mediatek/contacts/SpecialCharSequenceMgrProxy.java
這個文件主要就是寫入的暗碼修改命令
針對不同的讀取狀態(tài)，進行狀態(tài)切換 ? ?
