I presume you are talking about IDE drives?

The HAL needs to export a few macros, HAL_IDE_READ_UINT8,
HAL_IDE_WRITE_UINT8, HAL_IDE_WRITE_CONTROL etc.

The pcmb IDE macros just look at the usual address for IDE
controllers.

The file packages/hal/arm/xscale/picasso/current/src/picasso_ide.c

might give you ideas for a PCI IDE controller.
