How is this right ?

There's only one physical chip-select line per SPI master...

It's a 1:1 mapping.

Now, we have another board which can support 4 slave spi per master, but not only Galileo. Since that board is not public, after discussing with team, we decide to make the
upstream code to support '1'.

I will change it back to 
.num_chipselect = 1,

Best,
