Everyone:
This series contains all of the changes I made in order to add support
for NVME storage in Barebox. Majority of the code was adapted directly
from Linux kernel and I tried to keep it as close to the original as
possible. Only a very basic featureset was implemented:
- For obvious reason all of the request both to admin and I/O
queue are fully blocking/syncronous, so none of the I/O
operations are done in parallel
- PRP list only DMA (no SGL lists support)
- No support for shared namespaces
- No support for transports other than PCIe. All of the pluming to
add support for it should be there, however.
- Host memory buffer support is not implemented
Feedback is welcome!
Thanks,
Andrey Smirnov
