It seems that currently both atmel & davinci boards supports only 1 spi instance at a time.
In order to support different spi instances, In case of atmel declare SPIx_BASE as required & set CONFIG_DEFAULT_SPI_BUS to required bus In case of davinci set CONFIG_SYS_SPI_BASE to base address of required spi instance
Also, spi_cs_is_valid() function needs to be updated to support different spi instances. spi_cs_is_valid() function is board dependednt.
Hope this helps.

Hi Gururaja,
It seems that the implementation limit the validity only for bus==0. This means that trying other bus(=spi port ?) will fail even if its not at the same time. In addition to that the CPU's data sheet make no limit.
