Are you sure that your image is working at all? Does it boot when you
download it over TFTP and boot then?

You should know the memory map of your board better that we.  In  any
case it seems likely to me that there is flash or ROM at address 0 on
your  board,  and  not  RAM,  so  using  0x0000 as load & entry point
address is obviously plain wrong.

Neither one nor the  other.  U-Boot  is  _attempting_  to  start  the
kernel, which is not there where you pretend it is.
