This brings over the few know-how items and little things I found about the BCMBCA LEDs in my previous duplicate driver. This was tested on the BCM6846-based Genexis XG6846B. The main addition is the ability to define the number shifting bits in the serial shift register which is necessary if the previous boot stages have not set up the hardware properly before.
