Steven/Aaron,
I found the problem. On my board, the CF is on a 16 bit interface on bus
of MPC8248. The HW is connected in Big Endian format. PPC Bit D0 is
connected to CF Bit D15, and PPC D1 to CF Bit D14, till PPC D0 to CF
D15. I had to swap the bytes in u-boot. I forgot to do it in Kernel.
After making the change, CF is detected. But I can not access /dev/hda
or any scsi/sda devices under /dev.
# cd /dev
# ls *hd*
hda hda10 hda12 hda14 hda16 hda3 hda5 hda7 hda9
hda1 hda11 hda13 hda15 hda2 hda4 hda6 hda8
# ls *sda*
ls: *sda*: No such file or directory
# ls *scsi*
ls: *scsi*: No such file or directory
# mount -t msdos /dev/hda /mnt
mount: mounting /dev/hda on /mnt failed: No such device or address
Any insights/suggestions?
I am not sure if I need to use CONFIG_BLK_DEV_SD=y. I use it anyway, and
saw
Driver 'sd' needs updating - please use bus_type methods
On console.
I don't know how to fix this.

On my board, I get the following:
ata1: PATA max PIO6 mmio cmd 0x1c1000000 ctl 0x1c1000098 irq 32
Note that the addresses I provided got turned into 36-bit addresses
because I am using a PPC440EPx chip.
I am suspicious of the addresses you got, but I don't know enough
about how the mpc8248 sets up its memory map. Perhaps someone with
knowledge of that chip can comment.
Have you hooked a logic analyzer to the device? You should be sure
that the chip selects are really responding at the reported addresses.
Since the CF works with Uboot, at least we know the hardware is good.
