The following format worked for me Cedar Trail Canoe Creek boards:
SYSLINUX_OPTS = "serial 3 115200"
SERIAL_CONSOLE = "115200 ttyS3"
APPEND += "console=ttyS3,115200 console=tty3"
This format is based on Fish River 2 BSP:

Subject: [yocto] serial consoles
I have the meta-cedartrail image running on hardware (Marshalltown
board). To make the serial console work, I have in the
machine/cedartrail.conf file:
SERIAL_CONSOLE = "115200 ttyS0"
this works fine, but only after Linux is up and the login prompts are
sent out. I'm trying to also get the Kernel boot console log out, and
possibly syslinux or grub console.
If I look at the release notes for the meta-n450, it has suggestions to
do this for that BSP as below:
# Serial Port Setup for Intel Embedded Development Board 1-N40
SYSLINUX_OPTS_atom-pc = "serial 0 115200"
SERIAL_CONSOLE_atom-pc = "115200 ttyS0"
APPEND_atom-pc = "console=ttyS0,115200 console=tty0"
However, those notes talk about added these statements to the
local.conf file.
I have not been able to translate what works on the n450 to cedartrail.
Any ideas?
