I experienced similar problems with the serial ports on mpc5200 PSCs
and so i was happy to find your patch, which solved some problem, but
not all. The overrun flag still wasn?t reset after an input overrun
error, so this error was reported persistent for each received character.
I fixed this by adding an command to reset the psc error flags in
receive_char() where the overrun flag is checked. Maybe this isn't
the best solution, but it seems to work.
To reset the overrun error flag, i tried the following statement:
out_8(&psc->command, MPC5xxx_PSC_RST_ERR_STAT);
but i got unpredictable behaviour in some cases ending in a reset.
Doing the same this way:
psc->command = MPC5xxx_PSC_RST_ERR_STAT;
always worked as expected. Does someone know what may be wrong with
'out_8' on mpc5200 with kernel 2.4.25 or is that a configuration problem.
By the way, i improved some other parts of the code, especially the
/proc output and the portconfig stuff, so i also attach a patch here,
even not all of it may be useful.
