Asus P2B-LS board status upload after C environment bootblock conversion

[Paul Menzel]

Dear Keith,

Thank you for uploading the logs of the Asus P2B-LS to coreboot’s board 
status repository [1].

asus/p2b-ls/4.11-711-gd913036e18/2020-01-05T00_12_56Z

Two notes:

1.  The version in the logs unfortunately contain the *dirty* tag. Could 
you run `git status` or `git diff` to see what the differences are and 
maybe upload “clean” logs?

2.  Please rebuild CBMEM, so it knows about all time stamp names.

3.  With C environment bootblock CBMEM timestamp collection seems to 
work now.

romstage seems to take 3 seconds, which seems a lot. Do you have serial 
logs with timestamps, for example, `readserial.py` in SeaBIOS’ 
repository, for comparison with romcc bootblock? (Or you can enable to 
have timestamps printed to the console, so they

Please rebuild cbmem.

That is probably due to having the serial console enabled. Could you 
please do one upload with the serial console disabled?

Is the boot time really that long, and was it the same with romcc bootblock?

Kind regards,
