http://perforce.freebsd.org/chv.cgi?CH=98926 Change 98926 by imp@imp_lighthouse on 2006/06/10 18:09:18 Initialize the SD card, load the first 16MB of the card into RAM and jump to it. This is a big hack to get something that we can boot off of. the SPI part is too small w/o compression, and compression doesn't work for large kernels (and kernels?) with big ram disks.
