Oh, so you mean because spi_init is generic? I think you could simply do
something like:
<pre>
if (priv == g_spi0dev)
{
#ifdef BOARD_SPI0_MISO_PIN
/* use pin for SPI, configure it */
#else
/* set SPI to not use it */
#endif
}
else if (priv == g_spi1dev)
{
#ifdef BOARD_SPI1_MISO_PIN
/* use pin for SPI, configure it */
#else
/* set SPI to not use it */
#endif
}
/* ... and so on */
</pre>
If you had the g_spiNdev in an array this could be further simplified with a
parametrized macro
taking the instance number.
