Cover letter [patch 0/2] sata_via: bugfixes for vt6420 and vt6421

Dear all,

The following patches fix two bugs I encountered in the sata_via driver.

- DMA/PIO timings for the pata slave drive on a vt6421 were not handled correctly.

- ATAPI DMA corruption on a vt6420. At least for some burners, the vt6420 needs a small delay between sending the CDB and starting DMA to prevent silent data corruption. I found this solution by experimentation and while it works great for me, it might not work for everyone. Reports of success or failure are appreciated.

Some more background is included in the individual patches.

Groeten,
Bart
