We've done the direct connect route on a couple of our platforms (formerly Sandburst Metrobox). Unfortunately, as you state, you lose HS caps. We used two chip selects, and connected the bus as follows: EBC Addr 28:30 <-> CF Addr 2:0 EBC Data CF Data 8 15 9 14 10 13 11 12 12 11 13 10 14 9 15 8 0 7 1 6 2 5 3 4 4 3 5 2 6 1 7 0 /OE & /CSEL are pulled down /REG & /WE are pulled up. Check out Das U-Boot Sandburst Metrobox (include/configs/METROBOX.h) for usage info. We essentially used a technote/appnote from Toshiba (that I can't find right now). Good luck, travis
