Thanks for the help!  I cloned your u-boot-microblaze repository, and 
the same fit_hdr_t issues applied; now I'm also working out other 
various issues.  If it would help, I can attach (or send) my project 
file or files, and even an image of the CompactFlash card I am using -- 
it's a 1GB card, with a 100MB fat16 and the rest in ext2.  Oddly enough, 
ext2ls just plain returns silently.

u-boot-microblaze/drivers/mtd/cfi_flash.c:2088: undefined reference to 
`monitor_flash_len'

I've also noticed that the "top" BSP looks in the Xilinx install path 
and the project path, but not the EDK user repository.

Thanks again for the help.
