2022-03-18sdide: add pci id for AMT IDE-r controller on x230cinap_lenrek

2020-09-13kernel: massive pci code rewritecinap_lenrek
The new pci code is moved to port/pci.[hc] and shared by all ports. Each port has its own PCI controller implementation, providing the pcicfgrw*() functions for low level pci config space access. The locking for pcicfgrw*() is now done by the caller (only port/pci.c). Device drivers now need to include "../port/pci.h" in addition to "io.h". The new code now checks bridge windows and membars, while enumerating the bus, giving the pc driver a chance to re-assign them. This is needed because some UEFI implementations fail to assign the bars for some devices, so we need to do it outselfs. (See pcireservemem()). While working on this, it was discovered that the pci code assimed the smallest I/O bar size is 16 (pcibarsize()), which is wrong. I/O bars can be as small as 4 bytes. Bit 1 in an I/O bar is also reserved and should be masked off, making the port mask: port = bar & ~3;

2014-05-02sdide: never timeout or retry scsi commands from the controller drivercinap_lenrek
this was a big mistake. we should never attempt to timeout or retry a scsi command from the controller driver because theres no way to tell how long a command would take or if a command has side effects when being retried.

2012-12-26sdide: packet io byte count.cinap_lenrek
instead of setting the packet io byte count to some bullshit value, use the dlen from the scsi request. limit transfer byte count to 32k for atapi.
