This is off topic here. Please post to a Linux related list.
But I can tell you so much: just chosing a random board configuration and hoping it would work is always a pretty reliable way for a big disappointment. You actually have to *port* Linux to your hardware.
We were surprised to see that a "make uImage" would use the vmlinux.gz kernel (linked at 0xc000.0000) and not the zImage.elf(linked at 0x0040.0000), which includes the files in arch/ppc/boot/simple.
Why are you surprised?
The serial console is initialized and handled in ./arch/ppc/boot/simple/m8260_tty.c, and we suspect that since this is not included in vmlinux, that is the reason why we don't see any messages.
You misunderstand. The Linux bootstrap loader is never used with U-Boot.
Should we try to somehow add it to vmlinux (if this is possible)?
Don't.
I know this is not the list, but why is the linux make file is generating these two different files? My guess is that zImage is for systems with no u-boot bootloader.
Right.
