How to keep enabled splash screen on LCD while booting from u-boot to kernel

Hi Freescale Team ,

While booting when the control goes to kernel from u-boot ,the  splash screen intialised by u-boot will get turned off and will come again only after kernel is booted. When I cross checked the u-boot I saw ipuv3_fb_shutdown function to be called from arch_preboot_os which is called from do_bootm function.

In u-boot mailing lists ,it is shown that they added this fix to disable video as the kernel was hanging with video enabled.

So can u suggest any method to keep LCD enabled through out the booting process that is from u-boot to kernel?

In Android QuickStart guide it mentiones you should pass "fb0base=0x27b00000" to kernel at bootime when using LVDS screen. This may need adjusting depending on your u-boot setup (how/where memory is allocated for framebuffer).
