Product LED port
In linux kernel since version 2.6.12  
The ETRAX network driver is responsible for flashing LED's when
packets arrive and are sent. It uses macros defined in
<file:arch/cris/include/asm/io.h>, and those macros are defined after
what YOU choose in this option. The actual bits used are configured
separately. Select this if the LEDs are on a memory-mapped latch
using chip select CSP0, this is mapped at 0x90000000.
Some products put the leds on PA or PB instead.
