Hi

The following patch updates the new CPM1/CPM2 uart driver.

It seems to lose queued characters from the kernel output when userspace
/dev/console is first opened. Should you drain the FIFO before resetting
the hardware on open? Or indeed refrain from resetting the hardware if
you're not actually changing anything?

I haven't seen this problem on 8xx myself.

8265 here.

VFS: Mounted root (nfs filesystem).
Freeing unused kernel memory: 100k iné
sh-2.05b#

Hi there.

The following patch fixes the problem by properly waiting
two character times on mode change.
