Apart from the necessity to do this change for multi-platform kernels the previous logic depended on the zImage decompressor to write the physical and virtual address to a magic memory location. If the decompressor is unused or not correctly configured for the current machid, the addruart macro was an infinite loop. Moreover debugging the early zImage code was not possible either.

Fix debug port choice config dependency for traditional DaVincis. Modify debug port config names and add help text.] Signed-off-by: Sekhar Nori <nsekhar@ti.com>
