I'm working on porting u-boot to my custom HW (using MPC8347E) and I'm curious about the CONFIG_MPC83XX flag. I started with a copy of the MPC8349ITX.h file for my config and it defines CONFIG_MPC834X and CONFIG_MPC8349. But there's a field called bi_immrbar in the bd_info struct (.../include/asm-ppc/u-boot.h) surrounded by a check for CONFIG_MPC83XX. Now it seems to me that this field should be applicable to the 834x processors as well. So my questions is two fold: 1) why doesn't the MPC8349ITX board define CONFIG_MPC83XX to pick it up, and 2) should I be doing so for an MPC8347E processor?

Thanks.
