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.

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.
