Author: imp Date: Fri Jul 27 05:37:01 2012 New Revision: 238823 URL: http://svn.freebsd.org/changeset/base/238823
Log: Document the dataflash/mmc-sd issue. Add umass driver and usb. Boot off da0s1a instead of ate0. Note that MMC/SD is slot B. Until I switch over to NAND boot, dataflash booting will preclude having SD cards inserted at boot, so this last bit is untested. My SAM9260-EK not boots to multi-user prompt.
