Local variable @action usage in ata_eh_reset() is a bit confusing.
It's used only to cache ehc-i.action to test reset masks after

Port / host stop calls used to be made from ata_host_release() which
is called after all hardware resources acquired after host allocation
are released. This is wrong as port and host stop routines often
access the hardware.

I hope that standard AHCI eventually supports this nice feature

Speaking of which. Do we have a strategy as to how to implement/support

MMmm.. I wonder what the most common use case is for target mode?
Everybody I've dealt with thus far uses it as a high-speed local comms

Some BIOSen map AHCI ABAR but lock the SATA controller to IDE mode.
This patch add quirk to set AHCI mode on ICH board with such case.
Tested on Macbook2,1 (ICH7M)
Intel will complain but it's awful tempting...

The inability to do this in the general case is the main reason why
AHCI was not unconditionally enabled, even in IDE mode, when

The proposed sata_nv patch does the opposite -- guarantees we must

Such patches are OK for the test lab, but in this specific case users

At least for NVIDIA controllers, loading the AHCI driver when the BIOS

What workarounds, if any, are needed?
