- move the functions to access physical PCI configuration space from pci_pt.c to the new file dm/hw/pci.c, so they can be accessed in sharing mode as well. The new folder dm/hw is created in order to move APIs talking to physical PCI devices out of dm/vpci. - move the common vpci code from header file pci_priv.h to core.c. - move file include/dm/vpci/vpci.h one level up. It seems the folder include/dm/vpci is not necessary. - This patch only moves code around, and doesn't make any logical changes. Besides removes the static keyword from pci_pdev_read_cfg() and pci_pdev_write_cfg() Tracked-On: #1568 Signed-off-by: dongshen <dongsheng.x.zhang@intel.com> Signed-off-by: Zide Chen <zide.chen@intel.com> Reviewed-by: Li, Fei1 <fei1.li@intel.com> Acked-by: Eddie Dong <eddie.dong@intel.com>
