Why do I see additional BAR’s reported when executing the lscpi command for Intel® Arria® 10 Hard IP for PCI* Express?

Due to a problem in Intel® Quartus® Prime software version 18.0 and earlier you may see additional BAR’s reported by lspci when using the Intel® Arria® 10 Hard IP for PCI* Express. See the example below:

lspci -nn -vv -s 0000:04:00.0

Region 0: Memory at 11b0200000000 (64-bit, prefetchable) [disabled] [size=128M]
Region 2: Memory at 11b00f0200000 (32-bit, non-prefetchable) [disabled] [size=16]
Region 3: Memory at 11b00f0200010 (32-bit, non-prefetchable) [disabled] [size=16]
Region 4: Memory at 11b00f0200020 (32-bit, non-prefetchable) [disabled] [size=16]
Region 5: Memory at 11b00f0200030 (32-bit, non-prefetchable) [disabled] [size=16]

This problem has been fixed starting in the Intel® Quartus® Prime software version 18.1.
