Hi Kevin,

The use case is that on many boards there is a BMC emulating a 
keyboard/mouse device (the Aspeed AST2500 in our case). This device is 
always on, and enumerated first.

This meant that in our case we were never able to use both a "real" 
keyboard to select the boot mode in SeaBIOS, and the network KVM via the 
Aspeed at the same time.

With this patch (and multiple keyboards configured in Kconfig) we do not 
have this limitation anymore, and can use both the network KVM remote, 
as well as a "real" keyboard on the device to select e.g. network boot 
or USB install medium.
