at the coreboot CBMEM console messages board status repository,
you’ll find a lot of truncated preram CBMEM console messages.
Currently the buffer size is 0xc00 – 3 kB, right –, which is too small
for quite some boards. The mainboard *Kabylake LPDDR3 RVP3* overrides
it to 0xd00.
So I am thinking about increasing it , but it’s of course not that
simple, especially as I don’t understand all the implications.

This means a lower stack size (higher console buffer size) would result
in a stack overflow. In other words, a brick.
One more question. How was the size 0xc00 chosen in the first place?
 mentions log output of above 2KiB. Looks like it was just rounded up
to 3KiB. But I doubt that all boards were tested if any gives more out-
put by default.
