Workspace is RAM.  If your memory controller isn't set up, you can't use 
the workspace.  From your config file it looks like you're planning on 
using some kind of cache for SRAM.  I'd just skip this for now.  Delete 
the WORKSPACE line and you should be able to write to flash.  It'll be 
dog-slow, though.

For my 64Mb Spansion GL flash I use:

CHIPTYPE    MIRRORX16   ;Flash type: Spansion
CHIPSIZE    0x800000    ;The size of one flash chip in bytes
BUSWIDTH    16          ;The width of the flash memory bus in bits (8 | 
16 | 32 | 64)

Yours will probably be the same, but size will be 0x1000000.  I'm 
assuming your flash is 128Mb and not 128MB, but I apologize if this is 
wrong.
