Oh, yes. SCSI emulation is just what Linux embedded world is asking for...

Well ATAPI is SCSI emulation (its a sort of pidgin SCSI admittedly).

I'm actually seeing two strands of requests (including from embedded)

- CF only small "dumb as president" type driver that is written to be as
compact as possible and preferably considers IRQs as optional
- Full SATA and NCQ aware platform support.

I think that such diverse requests are coming from the different sectors of the embedded market, e.g. consumer electronics and carrier grade respectfully (Octeon probably being an exception here) which different greatly in the horsepower of the backing CPUs -- with carrier grade CPUs being multicore CPUs running at several GHz with a lot of memory (and using chipset ATA controllers) and the consumer electronics employing mostly RISC CPUs running at 200-300 MHz with not that much memory). The only SoC integrated SATA controller I know of in the embedded market is produced by Freescale, others continue embedding good old PATA controllers (although this is probably going to change given much lower pin count needed for SATA).
