As I've said: you are using a wrong "arcNumber". Doozan's u-boot is patched so 
that the arcNumber can be set as u-boot environment variable.
Basically arcNumber is just some term used by Doozan. In the Linux kernel it 
is called machine type. Have a look 
at /usr/src/linux/include/generated/mach-types.h for a complete list. There 
you'll find:
#define MACH_TYPE_DOCKSTAR             2998
#define MACH_TYPE_SHEEVAPLUG         2097
If you want your kernel to recognize the dockstar you have to use 2998 as 
arcNumber in u-boot.
