How do I determine the right string to put in this #define?  Looking
at all the .h files in u-boot-xlnx/include/configs, they vary a lot
and I didn't see this defined in any of the zynq board configs.

The flash I'm using is two 64MB devices (Spansion S25FL512S) in dual
stacked configuration.

When I run 'sf probe 0 0 0' from uboot, I get this:
SF: Detected S25FL512S_256K with page size 512 Bytes, erase size 256
KiB, total 128 MiB

Linux reports:
[    1.010771] m25p80 spi32764.0: s25fl512s (131072 Kbytes)

After some digging, I found this thread that indicates that MTD with
SPI flash is not supported, but there is experimental MTD translation
layer driver: http://u-boot.10912.n7.nabble.com/SPI-NOR-MTD-s-td178723.html#a178726

Does this still apply here?  Or are there Xilinx patches for this in
u-boot-xlnx?
