New Revision: 1203

Added:
   trunk/src/target/kernel/patches/config-nr-tty-devices.patch
Modified:
   trunk/src/target/kernel/patches/series
Log:
* decrease the number of VT devices to four, this gives a udev speedup.
  Also, we won't use that many VT's anyway.  It's a phone, after all

++	  This is the highest numbered device created in /dev. You will actually have
++	  NR_TTY_DEVICES+1 devices in /dev. The default is 63, which will result in
++	  64 /dev entries. The lowest number you can set is 11, anything below that, 
++	  and it will default to 11. 63 is also the upper limit so we don't overrun
++	  the serial consoles.
