There are already some kind of Bestcomm DMA engine supoprt for some embbeded system (ARCH=ppc). In order to speed up the developement, the API is (almost) compatible so we can use the drivers wrote for this API. For example, the Ethernet driver enterily rely on this API. However, the 'soon to be release' ATA driver has been rewritten. I did not at the time (yet) to look at rheap, but I know the current allocator is not really good (it can not free!). I was just thinking, as this code is alraedy in some Linux tree, we could still use it there, and plan to replace it by a much better one (keeping the API compatible) later on.
