Arun, J15 is the ball on the BGA package that I2C2_SCL is assigned to on the OMAP242x. The reason this may be important for some signals, is they may actually have multiplexing options to come out on a number of different balls. The I2C2_SCL only comes out on J15, so it is redundant, but for convention purposes, stating the ball is used.
