There have been lots of changes here recently, hopefully I can get
one of the MontaVista folks to explain the details.......

You need to at least configure CONFIG_BLK_DEV_IDE and
CONFIG_BLK_DEV_IDEDISK (whatever the proper questions are to set
these).  You have to be careful not to configure _too_ much, as
the 8xx port is a little sensitive to this (probing places where
it shouldn't).

Installing PCMCIA hard disk on DVK MPC823

[Phuc Le]

Hi There,

My name's Phuc Le. I am new on this field. I just installed
PCMCIA HDD on the the DVK MPC823 but it failed. Following
is step by step of the installing.

1. Install the embedded linux and cross-platform development
kit from Montavista in the pc-linux
2. Install the pcmcia package in there
3. Install the kernel patch supporting pcmcia
4. Install the pcmcia patch
5. Modify something belong to the document attached along with
the pcmcia package
6. Build and install the embedded kernel and also the pcmcia
7. Boot the DVK via tftp
8. Load pcmcia modules such as 'pcmcia_core.o', 'm8xx_pcmcia.o'
and 'ds.o'
9. Run the cardmgr

At this point everything really seemed to be OK.

10. Flug the pcmcia hard disk

The result was the cardmgr detects the flugged pcmcia device to be
ATA/IDE and it tried to load the 'ide_cs.o' module. But it failed. The error
message were displayed as below:

... ide_cs.o: unresolved symbol 'ide_register'
... ide_cs.o: unresolved symbol 'ide_unregister'

I tried to rebuilt the kernel with turn-on some IDE features in the
configuration phase and recompile the pcmcia based on the new kernel.

The result was still failed with the kernel to be panic status.

Have someone done this task? please tell me how to fix that.

Thanks in advances,
LMP
