I was hoping to use the SATA AHCI support but it looks like it hasn't been maintained. Hmm... I see an awful hack coming: you could try and define CONFIG_SYS_ATA_BASE_ADDR, CONFIG_SYS_ATA_IDE0_OFFSET and CONFIG_SYS_ATA_IDE1_OFFSET so that IDE0 points to the CompactFlash port and IDE1 points to the SATA compatibility register. Not sure how this would work out as a not-so-quick-but-very-dirty fix. The cleaner way would be to modify cmd_ide.c to not limit itself to two ports, and not use offsets but a real port base, and then in your case, properly declare IDE0 and IDE1 for CompactFlash and SATA respectively. I had started such work, actually, to support a LaCie board with two SATA controllers with four ports each; I'll try and dig it out.
