It would be helpful if you had given a little more information,  like
which   architecture  and  processor  this  is,  and  which  graphics
controller.

No, usually you don't need any board specific LCD driver code.

And yes, there is code that can be reused.

And no, I cannot be more specific, as your question was so vague.

Best regards,

architecture is mips, and processor is 4KEC
the LCD controller is Samsung LTS222QV-F01

Then start inplementing the framebuffer driver for  this  controller;
the  logo and splash-screen features will just fall in place once you
got this running.
