PCI: pci-epf-test: Use pci_epc_get_features() to get EPC features

2019-02-15T10:01:16+00:00

Use pci_epc_get_features() to get EPC features such as linkup
notifier support, MSI/MSIX capable, BAR configuration etc and use it
for configuring pci-epf-test. Since these features are now obtained
directly from EPC driver, remove pci_epf_test_data which was initially
added to have EPC features in endpoint function driver.

PCI: pci-epf-test: Do not allocate next BARs memory if current BAR is 64Bit

2019-02-15T10:00:18+00:00

It's useless to allocate memory for next BAR if the current BAR is a
64Bit BAR. Stop allocating memory for the next BAR, if the current
BARs flag indicates this is a 64Bit BAR.

PCI: pci-epf-test: Remove setting epf_bar flags in function driver

2019-02-15T10:00:09+00:00

Now that pci_epf_alloc_space() sets BAR MEM TYPE flags as 64Bit or
32Bit based on size, remove setting it in function driver.

PCI: endpoint: Fix pci_epf_alloc_space() to set correct MEM TYPE flags

2019-02-15T09:59:48+00:00

pci_epf_alloc_space() sets the MEM TYPE flags to indicate a 32-bit
Base Address Register irrespective of the size. Fix it here to indicate
64-bit BAR if the size is > 2GB.

PCI: endpoint: Add helper to get first unreserved BAR

2019-02-15T09:59:40+00:00

Add a helper function pci_epc_get_first_free_bar() to get the first
unreserved BAR that can be used for endpoint function.

PCI: endpoint: Add new pci_epc_ops to get EPC features

2019-02-14T16:08:10+00:00

Add a new pci_epc_ops ->get_features() to get the features
supported by the EPC. Since EPC can provide different features to
different functions, the ->get_features() ops takes _func_no_ as
an argument.

PCI: endpoint: functions: Use memcpy_fromio()/memcpy_toio()

2019-02-13T09:50:58+00:00

Functions copying from/to IO addresses should use the
memcpy_fromio()/memcpy_toio() API rather than plain memcpy().

Fix the issue detected through the sparse tool.

PCI: consolidate PCI config entry in drivers/pci

2018-11-23T02:45:34+00:00

There is no good reason to duplicate the PCI menu in every architecture.
Instead provide a selectable HAVE_PCI symbol that indicates availability
of PCI support, and a FORCE_PCI symbol to for PCI on and the handle the
rest in drivers/pci.
