MTK 6589暗码切换开机LOGO（不适应NAND 的FLASH）

MT6589 暗码更改开机LOGO
一。lk logo 修改
   1.  kernel\kernel\ power\main.c  （创建节点，控制logo切换状态）
#if 1//HIGUA
// for set_env() by mtk
#include <mach/env.h>
#endif

...
#if 1// HIGUA
ssize_t custom_changelogo_show(struct kobject *kobj,
                                    struct kobj_attribute *attr,
                                    char *buf)
{
      char *val = NULL;
      if(NULL != get_env("changelogo")){
            val = get_env("changelogo");
      }
      return sprintf(buf, "%s\n", val);
}
/*---------------------------------------------------------------------------*/
ssize_t custom_changelogo_store(struct kobject *kobj, struct kobj_attribute *attr,
                     const char *buf, size_t n)
{
if(!strncmp(buf,"1",1))
{
      set_env("changelogo", "1");
}
else if(!strncmp(buf,"0",1))
{
      set_env("changelogo", "0");
}
return n;
}

static struct kobj_attribute custom_changelogo_attr = {
      .attr       = {
            .name = "custom_changelogo",
            .mode = 0777,
      },
      .show       = custom_changelogo_show,
      .store       = custom_changelogo_store,
};
#endif

   static struct attribute * g[] = {
...
#if 1// HIGUA
      &custom_changelogo_attr.attr,
#endif
      NULL,

   }

2. mediatek\platform\mt6589\lk\mt_logo.c （根据logo状态显示不同的logo）
//这里的 38 是自定义logo的显示序号在下面会介绍
void mt_disp_show_boot_logo(void)
{
...
            #if 1//higua change logo
      if(get_env("changelogo") != NULL && atoi(get_env("changelogo")) == 1){
         show_logo(0);
      }else{
         show_logo(38);
      }
            #else
            show_logo(0);
            #endif
      mt_disp_update(0, 0, CFG_DISPLAY_WIDTH, CFG_DISPLAY_HEIGHT);

...
}

  3.mediatek\platform\mt6589\lk\platform.c  (现在一进入recovey 就会设置切换logo的属性，正常的应该是在恢复出厂设置的时候 )
void sw_env()
{

...
#if 1 // higua restore change logo
      if(g_boot_mode == RECOVERY_BOOT){
            set_env("changelogo","1");
      }
#endif

#ifndef USER_BUILD
switch (g_boot_mode)
{
   case META_BOOT:

...
}
4. mediatek\custom\common\lk\logo\rules.mk （添加 logo 图片）
   上面用到的 38 序列号就是  RESOURCE_OBJ_LIST 所有文件的顺序，添加的logo 是第38个位置的图片
         $(BOOT_LOGO_DIR)/$(BOOT_LOGO)/$(BOOT_LOGO)_bat_100.raw \
         $(BOOT_LOGO_DIR)/$(BOOT_LOGO)/$(BOOT_LOGO)_normal_uboot.raw \
         $(BOOT_LOGO_DIR)/$(BOOT_LOGO)/$(BOOT_LOGO)_kernel.raw

   还需要在对应的 logo目录里添加一张BMP图片
   例：我们的工程是 cu_hd720 所以在  cu_hd720 文件夹下添加一张 cu_hd720_normal_uboot.bmp 图片
   mediatek\custom\common\lk\logo\cu_hd720\cu_hd720_normal_uboot.bmp

二。kernel logo 修改
   1.mediatek\external\boot_logo_updater\boot_logo_updater.c （判断是否显示临时的logo文件）
int main(void)
{
...
// (3) open logo file
#if 1//higua
if ((fd = open("/data/mdl/local_boot_logo", O_RDONLY)) < 0) {
      if ((fd = open(LOGO_PATH, O_RDONLY)) < 0) {
                     fprintf(stderr, "failed to open logo file: %s\n", LOGO_PATH);
                     goto done;
            }
}
#else
if ((fd = open(LOGO_PATH, O_RDONLY)) < 0) {
      fprintf(stderr, "failed to open logo file: %s\n", LOGO_PATH);
      goto done;
}
#endif
// (4) map framebuffer

...
}
三。开机动画修改
   1.<a class="relatedlink" href="http://bbs.16rd.com/misc.%3Ca%20href=" target="_blank" forum-355-1.html"="" bbs.16rd.com="">php?mod=tag&id=6090" target="_blank" class="relatedlink">Frameworks\base\cmds\bootanimation\BootAnimation.cpp
status_t BootAnimation::readyToRun() {
...
if (bBootOrShutDown) {
      status_t err = mZip.open("/data/local/bootanimation.zip");
            XLOGD("[BootAnimation %s %d]err=%d,%s,/data/local/bootanimation.zip",__FUNCTION__,__LINE__,err,strerror(-err));
            #if 1//higua
      if (err != NO_ERROR) {
         err = mZip.open("/data/mdl/bootanimation.zip");
               XLOGD("[BootAnimation %s %d]err=%d,%s,/data/mdl/bootanimation.zip",__FUNCTION__,__LINE__,err,strerror(-err));
            }
            #endif
      if (err != NO_ERROR) {
         err = mZip.open("/system/media/bootanimation.zip");
               XLOGD("[BootAnimation %s %d]err=%d,%s,/system/media/bootanimation.zip",__FUNCTION__,__LINE__,err,strerror(-err));
         if (err != NO_ERROR) {
            m androidAnimation = true;
         }
      }
} else {
      if (!bShutRotate) {
         status_t err = mZip.open("/data/local/shutanimation.zip");
            XLOGD("[BootAnimation %s %d]err=%d,%s,/data/local/shutanimation.zip",__FUNCTION__,__LINE__,err,strerror(-err));
              #if 1//higua
      if (err != NO_ERROR) {
         err = mZip.open("/data/mdl/shutanimation.zip");
                  XLOGD("[BootAnimation %s %d]err=%d,%s,/data/mdl/shutanimation.zip",__FUNCTION__,__LINE__,err,strerror(-err));
            }
            #endif
               if (err != NO_ERROR) {
            err = mZip.open("/system/media/shutanimation.zip");
                     XLOGD("[BootAnimation %s %d]err=%d,%s,/system/media/shutanimation.zip",__FUNCTION__,__LINE__,err,strerror(-err));
            if (err != NO_ERROR) {
                     mAndroidAnimation = true;
            }
         }
      } else {
         status_t err = mZip.open("/data/local/shutrotate.zip");

...
}
四。快速开机修改
1.mediatek\external\ipod\bootlogo.cpp (之前没改到这里，启动快速开机的时候 lk，kernel 都没生效，今天才解决这问题）
void mt65xx_boot_logo_updater_init(void)
{

...
      // (3) open logo file
#if 1//higua
if ((fd = open("/data/mdl/local_boot_logo ", O_RDONLY)) < 0) {
      if ((fd = open(LOGO_PATH, O_RDONLY)) < 0) {
            fprintf(stderr, "[ChargingAnimation]failed to open logo file: %s\n", LOGO_PATH);
                     goto done;
            }
}
#else
      if ((fd = open(LOGO_PATH, O_RDONLY)) < 0) {
      fprintf(stderr, "[ChargingAnimation]failed to open logo file: %s\n", LOGO_PATH);
      goto done;
      }
#endif
      // (5) copy the 2nd logo to surface info

...
}
...
#if 1//higua
static int custom_show_local_logo(void)
{
      int fd = -1;
if ((fd = open( "/data/mdl/local_boot_logo " , O_RDONLY)) >= 0){
            close(fd);
            return 1;
      }
      return 0;
}
#endif

void mt65xx_disp_show_boot_logo(void)
{
      XLOGD("[ChargingAnimation %s %d]index = 0 ,x_virtual=%d, vinfo.yres=%d \n",__FUNCTION__,__LINE__,x_virtual, vinfo.yres);

Region region(Rect(0, 0, x_virtual, vinfo.yres));
      status_t  lockResult = surface->lock(&info, ®ion);
      XLOGD("[ChargingAnimation %s %d]info.bits = 0x%08x\n",__FUNCTION__,__LINE__, info.bits);
      XLOGD("[ChargingAnimation %s %d]surface->lock return =  0x%08x,  %d\n",__FUNCTION__,__LINE__,lockResult,lockResult);
      if (0 == lockResult)
      {
            #if 1//higua
            if(1 == custom_show_local_logo()){
                     show_logo_surface(38);
            } else {
                     show_logo_surface(0);
            }
            #else
            show_logo_surface(0);
            #endif
            surface->unlockAndPost();
      }
return;
}
