+
+So, if you're not using devfs, you must create those inodes in /dev
+on the root filesystem used by your SA1100-based device:
+
+	mknod ttySA0 c 204 5
+	mknod ttySA1 c 204 6
+	mknod ttySA2 c 204 7
+	mknod cusa0 c 205 5
+	mknod cusa1 c 205 6
+	mknod cusa2 c 205 7
+
+Note that the old incorrect use of /dev/ttyS0 in order to use the serial port 
+won't work anymore.  This device node is reserved to the conventionnal 16x50
+UART which may appear on devices like PCMCIA modem, etc.
+
+In addition to the creation of the appropriate device nodes above, you must
+ensure your user space applications make use of the correct device name.
+The classic example is the content of the /etc/inittab where you might have 
+a getty process started on ttyS0.  In this case you have two choices:
+
+1- replace occurences of ttyS0 with ttySA0, ttyS1 with ttySA1, etc.
+
+2- in the occurence of 'ttyS0', you may consider replacing it with 'console'.
+   as in "T0:12345:respawn:/sbin/getty -L console 9600 vt100"
+
+(don't forget to add 'ttySA0', 'console', or the appropriate tty name 
+ in /etc/securetty for root to be allowed to login as well.)
+
+The use of /dev/console has the advantage of being independent of the real
+serial device used.  The kernel automatically forward all operations on
+/dev/console to the apropriate serial device.  The nature of the console may
+also be modified with a kernel command line parameter (see
+Documentation/serial-console.txt for the details).  Of course, 
+/dev/console must have been created as a char device with major 5 minor 1.
+
+Using /dev/console is also compatible with older kernels that used /dev/ttyS0.
+Therefore it is handy for ramdisk images which are targetted for different
+StrongARM platforms and older kernels.
