By the way I do not have a "CMC state machine binary", which it says: #We don't ship that, but booting without it is bound to fail in the src/southbridge/intel/sch/Makefile.inc file. What is it, how can get it?
Is it likely for that to cause this serial output problem??
Thanks in advance.

Are you able to use the serial port when the vendor BIOS/(U)EFI image is
used? Yes I can get output if I append the following to the kernel line in grub: console=ttyS0,115200 console=tty0
And I have also set the show POST codes on the debug console but it doesn't produce anything either..

Found Winbond W83627HF/F/HG/G (id=0x52, rev=0x41) at 0x2e Register dump: idx 02 20 21 22 23 24 25 26 28 29 2a 2b 2c 2e 2f val ff 52 41 ff fe c0 00 00 00 00 fe c0 ff 00 ff def 00 52 NA ff 00 MM 00 00 00 00 7c c0 00 00 00
CR24 (idx 24, in the above output) means control register 24, here is a
link to the
superio's datasheet:
http://www.itox.com/pages/support/wdt/W83627HF.pdf
Ok, I got it, but doesn't CR24 is set inside the w83627hf_set_clksel_48() function..
Yes it is, bit 6 (in control register 24), is raised in w83627hf_set_clksel_48() . http://review.coreboot.org/gitweb?p=coreboot.git;a=blob;f=src/superio/winbon...
I still got no output from the serial unfortunately? :(
