[coreboot] sgabios no console output from Seabios (was: coreboot Digest, Vol 113, Issue 17)

[Wen Wang]

Paul,

I am on an old coreboot branch for this Rangeley/fsp experiment. This branch only has cbmem.py utility. I seem to have issue running the python script on target. I will need to spend some time figuring out the problem or switch to the newer cbmem.c to check cbmem.

Meanwhile, as Wang Fei pointed out, I changed seasbios I/O port base address and I am able to see seabios output using sgabios as option rom.  

Thanks,

Wen

If you build and run the utility `cbmem` as shown below, what is the output of the last two commands?

        $ cd util/cbmem
        $ make
        $ sudo cbmem -l
        $ sudo cbmem -c


Thanks,

Paul
