flash_v2: packages/io/pci/current/src/pci.c annotate

annotate packages/io/pci/current/src/pci.c @ 1467:8ad4d297cbf8

* src/pci.c (cyg_pci_get_device_info): Added fix for devices that only implement the bottom 16 bits of an IO BAR. This is allowed by the standard but is very rare and mostly present in older devices only. Without this cyg_pci_allocate_io_priv() gets confused.
