Hello, Steven,

I realized that and made change, I use reg-shift of 1 which u-boot uses
and works for the CF.

localbus@f0010100 {
      #address-cells = <2>;                   
      #size-cells = <1>;
      compatible = "fsl,mpc8248-localbus",    
                   "fsl,pq2-localbus",
                   "simple-bus"; 
      reg = <0xf0010100 0x40>;                
      ranges = <0x3 0x0 0x30000000 0x10000    
                0x4 0x0 0x40000000 0x10000>;  

      pata@3,0 {
         compatible = "fsl,tr5000v2-pata", "ata-generic";
         reg = <0x3 0x0 0x10 0x4 0xC 0x2>;   
         reg-shift = <1>;                    
         pio-mode = <6>;                     
         // interrupts = <0x19 0x8>;         
         // interrupt-parent = <&PIC>;       
      };


U-Boot (1.3.4) shows this:

bus 0: OK
  Device 0: Model: SanDisk SDCFJ-128 Firm: HDX 2.27 Ser#:
116904C2505X4026
            Type: Removable Hard Disk
            Capacity: 122.5 MB = 0.1 GB (250880 x 512)


This is the console output after setting reg = <0x3 0x0 0x10 0x4 0xC
0x2>:

ata_host_alloc: ENTER
ata_port_alloc: ENTER
__ata_port_freeze: ata4294967295 port frozen
scsi0 : pata_platform
ata1: PATA max PIO6 no IRQ, using PIO polling mmio cmd 0x30000000 ctl
0x4000000c

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.

Any more insights/ideas?
