[ELDK] Problem in porting Linux on Kontron VCE405 powerpc board

Tue Feb 1 22:55:05 CET 2011

Hi Rajive,

Seems to me you're missing the FDT BLOB (read up on it
here<http://www.denx.de/wiki/DULG/LinuxFDTBlob>).
Basically you need to describe your hardware to Linux via a textual DTS
file (which you compile to a binary DTB file) loaded and burned exactly like
the kernel and fs images.

I suggest taking a look at arch/powerpc/boot/dts/ep405.dts for reference.
Just make sure to #define CONFIG_OF_LIBFDT and CONFIG_OF_BOARD_SETUP in your
u-boot board config. You will also need to fixup the BLOB
using ft_cpu_setup(blob, bd); on ft_board_setup (populating the BLOB with
information dynamically calculated by u-boot).

This, at least, is what I had to due on a PPC875 (not doing this or missing
something would display what you just described).
