2017-02-10MdeModulePkg/PciSioSerialDxe: Use MAX_UINT8 instead of PCI_BAR_ALLRuiyu Ni
When BarIndex equals to 0xFF, default value 0 is used as the BAR index. Though PCI_BAR_ALL and MAX_UINT8 shares the same value, using PCI_BAR_ALL is like to match any BAR not BAR 0, it's more proper to use MAX_UINT8 here.

2016-11-10MdeModulePkg/PciSioSerial: Fix a bug that wrongly produces 2 UARTsRuiyu Ni
When PciSioSerial is firstly started with a non-NULL remaining device path, the UART instance is created using the parameters specified in the remaining device path. Later when the driver is started again on the same UART controller with NULL remaining device path, the correct logic is to directly return SUCCESS instead of current buggy implementation which wrongly produces another UART using the default parameters. The bug causes two UARTs are created when the UART is configured in 57600 baud rate.

2015-12-14MdeModulePkg/PciSioSerialDxe: Fix compiler warningsMichael Kinney
Add missing braces in module global mControllerDevicePathTemplate. Initialize ControllerNumber and ContainsControllerNode in SerialControllerDriverStart() to address warning for potential use before initialization warning. Move initialization of local SerialIo earlier in SerialControllerDriverStart() to address warning for potential use before initialization warning.

2015-12-10MdeModulePkg: Add PciSioSerialDxe driverRuiyu Ni
PciSioSerialDxe driver can manages UARTs on a SIO chip or a PCI/PCIE card. It manages the SIO instance whose last device path node is a ACPI device path and the HID in the ACPI device path node equals to EISA_PNP_ID (0x501). It also manages the PCI IO instance whose class code is 7/0/2 (16550 UART). But when proper value is set to PcdPciSerialParameters, the driver can also manage non-standard PCI serial cards by matching the Vendor ID and Device ID specified in PcdPciSerialParameters. The PCI BAR index, IO/MMIO offset, register stride, clock rate can also be specified through the same PCD.
