Thank you for your help. In answer to your questions:
>>>Can you "see" the PCI IDE controller at this address? What's the
output of:

I believe not because

I suppose that the oxFF bytes are not correct for the contents of the
ide controller registers.
What should I look for?
I used 0xE8000000 (apparently incorrectly) because it was reported in
the following messages when initializing with the PPBBoot firmware:
PCI_Scan:Device 4 is present Bus Func 2000 ClassCode 101
IDE device found:

Done - see subject.

Correct. That's _not_ the IDE controller.

Hmmm. I/O access is not enabled. So any access to the I/O spaces will fail.

Also strange. I would expect the BAR's to be assigned to something like:
base address 0 = 0x008001f1
Then you could access this I/O space at 0xe88001f0. Here a dump from our
Walnut with a PCI IDE controller:
Found PCI device 00.01.00:
vendor ID = 0x1191
device ID = 0x0009
command register = 0x0007
status register = 0x02b0
revision ID = 0x10
class code = 0x01 (Mass storage controller)
sub class code = 0x80
programming interface = 0x00
cache line = 0x08
latency time = 0x80
header type = 0x00
BIST = 0x00
base address 0 = 0x00800001
base address 1 = 0x00800009
base address 2 = 0x00800011
base address 3 = 0x00800019
base address 4 = 0x00800081
base address 5 = 0x80000000
cardBus CIS pointer = 0x00000000
sub system vendor ID = 0x1191
sub system ID = 0x0009
expansion ROM base address = 0x40000000
interrupt line = 0x1e
interrupt pin = 0x01
min Grant = 0x0b
max Latency = 0x04
=> md.b e8800010 10
e8800010: 7f 7f 7f 7f 7f 7f 7f 7f ff ff 7f ff ff ff ff ff ................
Do you use the same PCI config setup as the Walnut in your board config file?
Do you use the lastest U-Boot version (current GIT or CVS version)?
Best regards,
Stefan
