PCMCIA without Card Services

I'm trying to build a kernel with components that will allow and IDE interface through the MPC8xx PCMCIA controller. I have a compact flash connected to the PCMCIA interface.



The PCMCIA controller is configured by the bootloader (u-boot).



In the kernel (v 2.4.26), I have the following configured: CONFIG_IDE=y CONFIG_BLK_DEV_IDE=y CONFIG_BLK_DEV_IDEDISK=y CONFIG_IDEDISK_MULTI_MODE=y CONFIG_BLK_DEV_MPC8xx_IDE=y CONFIG_IDE_8xx_PCCARD=y



On bootup, I get: ... Uniform Multi-Platform E-IDE driver Revision: 7.00beta4-2.4 ide: Assuming 50MHz system bus speed for PIO modes; override with idebus=xx ...



It seems that m8xx_ide_init_hwif_ports() never gets called to do the further initialization.



Why would this be the case? Am I missing an important CONFIG_ ??



Thanks in advance,



- Mike

To my knowledge, PCMCIA without cardservices just recently debuted in kernel 2.6.12-rc3-mm1. I don't think you can do that with 2.4

Thanks, Mickey.

I've seen references to this cofiguration and at first glance, it appears to be talking about v 2.4 kernel. Or so it appears so by the kernel config variables that are being used...one of which I know was obsoleted in 2.6....namely CONFIG_BLK_DEV_IDE_MODES referenced in the document:

Anyways, I got around my original problem another way and I'm going to continue using CardServices.

Thanks alot,

Actually, as it turns out, I may still need to do this without Card Services.

Does anybody have any information on this... which kernel versions support it?

Thanks,
