Subject: early_serial_setup is broken in the 2.5 series
Date: Sun, 15 Dec 2002 15:30:52 +0100 [thread overview]
Message-ID: <3DFC921C.1030302@murphy.dk> (raw)
As far as I can see early_serial_setup should be capable of being
used to dynamically setup a serial port at any time in the boot
process - this is certainly the case in the 2.4 kernels.
However if it is used during architecture initialization, for example,
then the serial8250_reg uart driver has not been registered and
initialized even though it is used in the early_serial_setup call.
What was wrong with the 2.4 implimentation where the registered
serial ports were saved until the serial driver was ready to use them?
