68 depends on SIBYTE_SB1xxx_SOC=y
72 Support for the asynchronous serial interface (DUART) included in
73 the BCM1250 and derived System-On-a-Chip (SOC) devices. Note that
74 the letter D in DUART stands for "dual", which is how the device
75 is implemented. Depending on the SOC configuration there may be
76 one or more DUARTs available of which all are handled.

131 Say Y here if you wish to have the internal AT91 / AT32 UARTs
132 appear as /dev/ttyATn (major 204, minor starting at 154)

134 64). This is necessary if you also want other UARTs, such as
135 external 8250/16C550 compatible UARTs.
136 The ttySn nodes are legally reserved for the 8250 serial driver
137 but are often misused by other serial drivers.
139 To use this, you should create suitable ttyATn device nodes in
140 /dev/, and pass "console=ttyATn" to the kernel.

789 The pmac_zilog driver for the z85C30 chip on many powermacs
790 historically used the device numbers for /dev/ttySn. The
791 8250 serial port driver also uses these numbers, which means
792 the two drivers being unable to coexist; you could not use
793 both z85C30 and 8250 type ports at the same time.
795 If this option is not selected, the pmac_zilog driver will
796 use the device numbers allocated for /dev/ttyPZn. This allows
797 the pmac_zilog and 8250 drivers to co-exist, but may cause
798 existing userspace setups to break. Programs that need to
799 access the built-in serial ports on powermacs will need to
800 be reconfigured to use /dev/ttyPZn instead of /dev/ttySn.
802 If you enable this option, any z85c30 ports in the system will
803 be registered as ttyS0 onwards as in the past, and you will be
