Block device IO


Hello,

I'am currently working on putting things together for
accessing block devices under eCos.

I have a simple IO layer to read/write blocks trough cyg_io_bwrite/read and
a synthetic device wich reads/writes blocks to and from file for testing.

On top on that I have a block cache layer wich caches blocks - the interface
used is the same (cyg_io_bwrite/read).

Now I'am thinking about a third layer to do the position -> block/offset translation.
Maybe it would be cleaner to put it into a library since the only way I see to set
block numbers is trough set_config interface (?) .


Is there any similar effort wich will be contributed back to eCos ?

I would like to keep things close to the way block devices will (or are planned to)
work under eCos because of further development.


thanx
savin
