A faulty PCI device has the Option ROM image size set to 0. UEFI reads
two headers PCI_EXPANSION_ROM_HEADER and PCI_DATA_STRUCTURE to get the
Option ROM information. Because the image size is 0, the Option ROM
header address never changes. As a result, UEFI keeps reading the same
two headers definitely. This patch is intended to fix it.

The return value stored in Status after call to SetDriveParameters
is not made of any use thereafter and hence it remains as UNUSED.
Based on Hao's findings (https://edk2.groups.io/g/devel/message/106844),
the successful execution of SetDriveParameters() is not mandatory for
initializing IDE mode of a hard disk device. Hence remove the 'Status'
assignment of the return value from SetDriveParameters() and instead add
error checks & DEBUG_WARN level messages within SetDriveParameters()
function after sending INIT_DRIVE_PARAM & SET_MULTIPLE_MODE ATA commands.

In RELEASE mode, if for whatever reasons there is no match inside the

there is no "Block" NULL pointer check afterwards and the code proceeds
to do dereferencing "Block" which will lead to CRASH.

This patch changes the return value to an EFI_STATUS so that when

Without this change, any FALSE returned by DiscoverScsiDevice()
will result in EFI_OUT_OF_RESOURCES being returned by
ScsiScanCreateDevice(), which will cause a while loop in
SCSIBusDriverBindingStart() to abort before other possible Puns in

Below code will calculate the reserved bus number for the each PF.
Based on the VF routing ID algorithm, PFRid and LastVF in below code
already sure that "All VFs and PFs must have distinct Routing IDs".
PF will be assigned Routing ID based on secBusNumber, ReservedBusNum
will add into SubBusNumber directly. So the SR-IOV device will be
assigned bus range as SecBusNumber ~ (SubBusNumber=(SecBusNumber +
ReservedBusNum)).
Thus "+1" in below code will cause extra 1 bus, and introduce a bus hole.
PFRid = EFI_PCI_RID (Bus, Device, Func);
LastVF = PFRid + FirstVFOffset + (PciIoDevice->InitialVFs - 1) * VFStride;

In SR-IOV spec, there is a note in section 2.1.2:
Note: Bus Numbers are a constrained resource. Devices are strongly
encouraged to avoid leaving ?holes? in their Bus Number usage to avoid
wasting Bus Numbers
So the issue can be fixed with below code change.
