As part of making the chip-specific mix and match of different accesses
(DMA/bus space) work as desired, the intent is to map the HCB memory as
uncacheable. Prior to VM_MEMATTR_*, the !x86 way of indicating this to
bus_dmamem_alloc(9) was BUS_DMA_COHERENT. Then later on in

It described how to install the driver, gave informations on driver features and summerized important changes between versions. These informations are now available using `man sym' for driver usage and features description, and `cvs log' for driver changes. I haven't removed this README file from the repository since I may have to provide additional documentation to people interested in understanding the driver sources and/or in helping driver development and maintenance. As a result, this file is now under reconstruction. :-) -- "Gerard Roudier"<groudier@free.fr>
