  +
  +static inline void iowrite(u32 val, u32 reg)

 Why not just use ioread32/iowrite32 directly ?

Because this increases readability and does not affect functionality at all

 Otherwise this looks way way better.

The IDE controller logic supports PIO, multiword DMA and ultra-DMA modes.
Supports interface to compact Flash (CF) configured in True-IDE mode.

Use ide_setup_dma() since BLK_DEV_PALMCHIP_BK3710 selects BLK_DEV_IDEDMA_PCI
So I deleted exports from ide-dma.c

[PATCH] Palmchip BK3710 IDE driver

2008-01-17 Thread Anton Salnikov

This is Palmchip BK3710 IDE controller support for kernel version 2.6.24-rc8.
The IDE controller logic supports PIO, multiword DMA and ultra-DMA modes.
Supports interface to compact Flash (CF) configured in True-IDE mode.

I had to export two functions (ide_dma_exec_cmd and __ide_dma_test_irq) from 
driver/ide/ide-dma.c to get rid of copying them.
