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.
