Feel free to add that. But like I mentioned in my reply, for all existing drivers, except for pci-keystone.c, in practice BAR_RESERVED actually means BAR_DISABLED. (Since all drivers except for pci-keystone.c call reset_bar() in init(), and pci-epf-test will not enable BARs marked as BAR_RESERVED). So if you add a BAR_DISABLED, make sure that you convert all existing uses of BAR_RESERVED (except for pci-keystone.c) to BAR_DISABLED. pci-keystone.c and pcie-tegra194.c can then be the only drivers that have BARs marked as BAR_RESERVED (all other drivers would use BAR_DISABLED). Please just make sure that you don't regress the amount of currently passing pci_endpoint_test test cases that are passing for pcie-tegra194.c. (Which would be the case if you revert the patch in $subject without first adding your proposed new BAR_DISABLED, such that we can have a distinction between BAR_DISABLED and BAR_RESERVED.)
