Follow-ups

there is no portmux code currently in the SPI driver for BF538/BF539

ok, even after fixing that, turns out there's nothing we can do.  whoever

designed the BF538F-EZKIT made a stupid SPI connector.  none of the SPI0 SSEL

pins are brought out to the header.

 

so do not test the SPI add-on card with the BF538F-EZKIT

OK, I see. So close this bug.
