We used to specify explicitly serial port with all its settings for init to instantiate getty. This limits usecases when the same one rootfs could be used. For example following cases won't work well with hardcoded serial console settings: * On the same board other serial port is expected to be used * The same rootfs is intended to be used on different boards with different serial ports (like ttySx vs ttyAMAx or even ttyx) With this change by default we rely on "console" specified in kernel's boot command line. What is important getty will be set on the last console specified in bootargs. For example is a kernel comand line: --->--- bootargs="... console=tty0 console=ttyS3,115200n8..." --->--- This now will instantiate serial console on ttyS3 but not on tty0. Tested with both Busybox and SysV init.
