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

[Andy Pont]

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.
