[U-Boot] ttyO2 and ttyS2 in console bootcmd.

U-Boot passes Linux kernel boot arguments in the "bootargs"
environment variable.  For U-Boot, this is just a variable setting.
U-Boot does not interpret it's content in any way.

U-Boot uses fixed configuration settings and has no notion of such
device names.

This sentence makes no sense to me.

We have no idea what "your custom uboot" might be. [Please note the
correct spelling: U-Boot.]
