The SPI functions should have never been part of the export interface. As far as I can see now, they have been added by commit bedd8403f7 export SPI functions to standalone apps While we're here, fix the broken #ifdef handling in _exports.h. Signed-off-by: Mike Frysinger <vapier@gentoo.org> in 2009. Actually I must even have seen them, as I complained about incorrect comment style :-( But no, SPI support should not be inclluded. I2C was there because it was needed for reading the environment from an EEPROM, but then the interface was frozen ano no more new interfices / drivers should be allowed. Viele Grüße, Wolfgang Denk
