Hi,
In drivers/ide/Kconfig at present, if you deselect
BLK_DEV_IDEDMA_PCI you can then *not* select any of the non-generic
chipsets. Thus you lose the ability to auto-tune PIO modes, for
example.
This patch rearranges where the endif moves to disable just the config
options that depend on DMA.

This allows the kernel to change PIO, DMA and UDMA speeds and to

Thats because otherwise you will have compile time hell.
