From 64d72bbeeb68b536a27319471f212d413f58bf6f Mon Sep 17 00:00:00 2001 From: Nicolas Ferre Date: Fri, 10 Sep 2010 11:26:42 +0200 Subject: AT91: at91sam9261ek board: remove warnings related to use of SPI or SD/MMC The sd/mmc data structure is not used if SPI is selected. The configuration of PIO on the board prevent from using both interfaces at the same time (board dependent). Remove the warnings at compilation time adding a preprocessor condition.
