Logo picture display from uboot to kernel

Chip: MIMX8MM6DVTLZAA

BSP:  L5.4.70-2.3.0

Question:

We need to display the same logo picture from uboot to kernel smoothly, but now we find that when switch from uboot to kernel, the screen will be black in a very short time and return to normal display.

We just know that we can initial the mipi and lcdif module only one time in uboot, and never initial again in kernel.

But, we don’t know how to close the initialization in kernel.

Hope you can help us.

Thanks.
