SPI ML507 Pins

Hi, I'm using the board of ML507.In EDK,I add the core of SPI,but now I have some problem.The errors is that: ERROR:MapLib:30 - LOC constraint P15 on xps_spi_0_MISO is invalid: No such site on the device. To bypass this error set the environment variable 'XIL_MAP_LOCWARN'. ERROR:MapLib:30 - LOC constraint N15 on xps_spi_0_SCK is invalid: No such site on the device. To bypass this error set the environment variable 'XIL_MAP_LOCWARN'. My ucf file is: ##SPI net xps_spi_0_SCK LOC=N15; net xps_spi_0_SCK IOSTANDARD = LVCMOS33 | SLEW=SLOW | DRIVE=6; net xps_spi_0_MOSI LOC=AF14; net xps_spi_0_MOSI IOSTANDARD = LVCMOS33 | SLEW=SLOW | DRIVE=6; net xps_spi_0_MISO LOC=P15; net xps_spi_0_MISO IOSTANDARD = LVCMOS33 | SLEW=SLOW | DRIVE=6; net xps_spi_0_SS<0> LOC=V9; net xps_spi_0_SS<0> IOSTANDARD = LVCMOS33 | SLEW=SLOW | DRIVE=6; What can I do to pass these errors.Thank you!
