[U-Boot] Splash Screen Enable in (u-boot-2013.01.01.tar.bz2) U-boot source code.

[nandakumar.ramaswamy at pricoltech.com]

Hello,
 
1) Please share me, if any one used mx53loco - LVDS settings for hannstar (mcimx-lvds1) display as per the below,
 
setenv bootargs_base 'setenv bootargs console=ttymxc0,115200 console=tty1 video=mxcdi1fb:RGB666,TOSHIBA-XGA di1_primary ldb=single,di=1,ch1_map=SPWG'
 
2) And I have modified the below files and codes for splash screen support for mx53loco as per the mx6qsabrelite.c. Please correct me, if I wrong.
 
File Name: mx53loco.h
 
Included:
#define CONFIG_SPLASH_SCREEN
#define CONFIG_SPLASH_SCREEN_ALIGN
#define CONFIG_SPLASH_SCREEN_LVDS
#define CONFIG_CMD_BMP
 
File Name: mx53loco_video.c
 
Include:
static struct fb_videomode const mcimx_lvds1 = {
 .name        = "Hannstar-XGA",
 .refresh    = 60,
 .xres        = 1024,
 .yres        = 768,
 .pixclock    = 15385,
 .left_margin    = 220,
 .right_margin    = 40,
 .upper_margin    = 21,
 .lower_margin    = 7,
 .hsync_len    = 60,
 .vsync_len    = 10,
 .sync        = 4,
};
 
int board_video_skip(void)
{
 int ret;
 char const *e = getenv("panel");
 
 printf("Display Panel Name: %s\n", e);

 if (e) {
 if (strcmp(e, "seiko") == 0) {
 ret = ipuv3_fb_init(&seiko_wvga, 0, IPU_PIX_FMT_RGB24);
 if (ret)
 printf("Seiko cannot be configured: %d\n", ret);
 return ret;
 }
 else if (strcmp(e, "Hannstar-XGA") == 0) {
 ret = ipuv3_fb_init(&mcimx_lvds1, 0, IPU_PIX_FMT_LVDS666);
 if (ret)
 printf("MCIMX_LVDS1 cannot be configured: %d\n", ret);
 return ret;
 }
 }

 /*
 * 'panel' env variable not found or has different value than 'seiko'
 *  Defaulting to claa lcd.
 */
 ret = ipuv3_fb_init(&claa_wvga, 0, IPU_PIX_FMT_RGB565);
 if (ret)
 printf("CLAA cannot be configured: %d\n", ret);
 return ret;
}

And I tried the below command. But not get the correct output (SPLASH Image) through U-Boot.
 
MX53LOCO U-Boot > tftp 100000 /tftpboot/lvds.bmp 
Using FEC device
TFTP from server 192.168.1.176; our IP address is 192.168.1.189
Filename '/tftpboot/lvds.bmp'.
Load address: 0x100000
Loading: T T T T T 
 
Please give your suggestion and solution ASAP.
 
Note: I am trying to display from SD-card.
 
Thanks & Regards,
Nandakumar R.

U-Boot release 2013.01.01 for mx53loco supports two LCD panels,
CLAA07LC0ACW and Seiko-43WVF1G. If you have a different panel, you
will have to add support for it. If you have Seiko panel, please set
up environment variable panel as follows:

=> setenv panel seiko
=> saveenv

and reboot, then use load a bmp file and use "bmp" command to display
it.

Thanks,

Anatolij
