DIP switches are set the same -- 1, 2, & 4 ON, 3 is OFF.

I set DEBUG as specified and this is the result:

I should point out that I've been using the board for about the last year
and a half, but with rrload.  I decided to switch over to u-boot and ran
into these problems.  A little investigating revealed that in the function
get_flash_size() in the file board/omap1510inn/flash.c, the probe for
manufacturer returns 0x12 and that doesn't match INTEL_MANUFACT which is
what's on the board.  After that things go downhill very rapidly.  I think
I'll look into what's going on in rrload to see if that will explain things.

Thanks for the help so far.
