Please do a quick experiment: eliminate (#if 0) contents of the  
platform_mpp_init() in sys/arm/mv/kirkwood/db88f6xxx.c and recompile/ 
rerun. The SP device could have MPP/GPIO layed out differently (note  
you're using DB-88F6281 dev board configuration): we could be  
overwriting UART lines connection settings and hence lose console  
output.
