Any SPI-4.2 Lite v5.1 core generated for Spartan-6 FPGA and used in ISE 11.3 will return the following error in Map:
ERROR:LIT:554 - OBUFTDS symbol
"core_pl4_lite_src_top0/U0/pl4_lite_src_io0/src_ddr[4].seto0.one_bit0/ddr0_bu
f" (output signal=TDat_P(4)) has its I input pin driven by an ODDR2 that is
using its D1 input. However, no ODDR2 was found driving the corresponding T
input pin. This will cause the design to not work in hardware. Please ensure
that OBUFTDS symbol
"core_pl4_lite_src_top0/U0/pl4_lite_src_io0/src_ddr[4].seto0.one_bit0/ddr0_bu
f" (output signal=TDat_P(4)) has its T input pin driven by an ODDR2.
