[U-Boot] SPL and an LCD splash screen on AM335x

Hello!

We are currently working on the specification for a project using the TI AM335x where the overall system boot time has to be reduced as far as possible. In order to achieve that I am proposing that we implement a board specific spl_start_uboot() function which under normal circumstances U-Boot SPL will load the Linux kernel directly.

One of the other requirements is to "display a splash screen logo on the LCD as early in the boot process as possible". Is it possible to get U-Boot SPL to do that or will we always have to boot through U-Boot or see if we can get the Linux kernel to do it as early as possible?

Thoughts and ideas welcome.

Andy.
