Not quite. Register access is covered quite well but DMA is still
roll-your-own. (Jason how are the bus_dma_*() accessors coming
along? Need help?)
Anyway, PCI DMA seems to be working pretty well in 64-bit SPARC although
32-bit seems to have some problems still. Have any other architectures
used PCI HME successfully? I wouln't be surprised it some htole*() or
htobe*() macros may be required when accessing DMA memory areas with PCI
