[SeaBIOS] coreboot: modifying seabios bootenter list dynamically

[Francesco Lucconi]

I'm looking for a simple method that enables a dynamic way to select one of
the several options listed into CBFS bootorder file but unfortunatelly I'm
finding out that this file is static and it could be edited and configured
just on build time.

My specific goal is about a dynamic OS bootstrapping or via USB storage
device or via pci netcard automatically without pressing any keyboard
buttons.

(the auto mode is guaranteed with a gpio signal that it is switches between
these 2 scenarios.)

Is it correct? Do you know if I can use it differently?
