Yeah, "qe_mode" variable is confusing, but it wasn't me who introduced it. ;-) So, "the SPI in QE running in CPU mode" is correct. [ Unrelated to that particular patch. Probably qe_mode should be renamed to something better, maybe spi_in_qe? Or we could back to discussion about auto detecting it somehow. ] > - k Thanks, -- Anton Vorontsov email: cbou-JGs/UdohzUI@public.gmane.org backup email: ya-cbou-o+MxOtu4lMCHXe+LvDLADg@public.gmane.org irc://irc.freenode.net/bd2 ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
