I have had the same problem with the MPC8266ADS board. In my case I think it turned out to be an inncorect serial console setting in arch/ppc/89260_io/uart.c

Hello,
I am trying to find anyone who has had success in using u-boot to boot an MPC8266ads kernel to give me a pointer or 2 in the right direction. I have rsync'd the latest 2.4 development kernel from penguinppc.org as it contains the appropriate drivers etc. for the board and have u-boot running on the board now. However, when I tftp the kernel to the board and try to bootm, I get:
Uncompressing Kernel Image ... OK
and then no progress from there. Looking through the users list and the README file, I noticed that the the bd_info has to be the same between u-boot.h and the kernel's appropriate header file; there is also some recommendations with regards to the "clocks_in_mhz" option and the synchronization of IMAP_ADDR and CFG_IMMR. I have also built the kernel by hand using the system detailed in the u-boot README file, with the objcopy;gzip -9; mkimage, all to no avail. If anyone has any insight in this regard, I would very much appreciate it.
Thanks in advance,
Currie Reid
