* ArmVirtPkg: Fix some spelling mistakes found by cspellRebecca Cran2024-08-011-14/+14
| | | | | | | | | | | When cspell is installed (via `npm install cspell`), CI checks for spelling mistakes. There are currently a very large number of them: some are genuine mistakes while others are words or acryonyms that cspell doesn't know. Fix a few of the misspellings in ArmVirtPkg.

* ArmVirtPkg: Move PCD of FDT base address and FDT padding to OvmfPkgChao Li2024-02-061-1/+2
| | | | | | | | | | | | | | | | | | | | | Moved PcdDeviceTreeInitialBaseAddress and PcdDeviceTreeAllocationPadding to OvmfPkg for easier use by other architectures. Build-tested only (with "ArmVirtQemu.dsc").

* ArmVirtPkg: introduce DebugLibFdtPL011Uart DXE Runtime instanceLaszlo Ersek2023-10-262-0/+149
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Introduce three new DebugLib instances, forked from MdePkg/Library/BaseDebugLibSerialPort. All three instances rely on PL011UartLib rather than SerialPortLib so that they can customize the PL011 UART that the debug messages are written to. All three instances direct the debug output to the first such PL011 UART that *differs* from the one specified in the Device Tree's /chosen node's "stdout-path" property. From these, DxeRuntimeDebugLibFdtPL011Uart is identical to DebugLibFdtPL011UartRam, with the addition that UART access is permanently disabled when the containing DXE_RUNTIME_DRIVER module is notified about exiting boot services. The contexts in which these DebugLib instances run are identical to those in which the corresponding SerialPortLib instances run. The particular original dependency chain is DxeRuntimeDebugLibSerialPort (DXE_RUNTIME_DRIVER) FdtPL011SerialPortLib gEarlyPL011BaseAddressGuid HobLib PL011UartLib and the new dependency chain is DxeRuntimeDebugLibFdtPL011Uart (DXE_RUNTIME_DRIVER) gEarlyPL011BaseAddressGuid HobLib PL011UartLib The ArmVirtPkg DSC files will be switched to the new library instances in a separate patch. This patch is worth viewing with "git show --find-copies-harder".

* ArmVirtPkg: introduce DebugLibFdtPL011Uart RAM instanceLaszlo Ersek2023-10-264-0/+229

All three instances direct the debug output to the first such PL011 UART that *differs* from the one specified in the Device Tree's /chosen node's "stdout-path" property. From these, DebugLibFdtPL011UartRam mirrors FdtPL011SerialPortLib: it relies on the EarlyPL011BaseAddress GUID HOB, and initializes the UART -- a UART different from FdtPL011SerialPortLib's -- only once in the lifetime of the containing module. Suitable for module types that can only execute from RAM (i.e., all types different from SEC, PEI_CORE, PEIM), except DXE_RUNTIME_DRIVER. (Note that OVMF uses a similar set of dedicated DebugLib instances (PlatformDebugLibIoPort) for logging to the (x86-only) isa-debugcon device from various firmware phases.) The contexts in which these DebugLib instances run are identical to those in which the corresponding SerialPortLib instances run. The particular original dependency chain is BaseDebugLibSerialPort (not SEC, PEI_CORE, PEIM, DXE_RUNTIME_DRIVER) FdtPL011SerialPortLib gEarlyPL011BaseAddressGuid HobLib PL011UartLib and the new dependency chain is DebugLibFdtPL011UartRam (not SEC, PEI_CORE, PEIM, DXE_RUNTIME_DRIVER) gEarlyPL011BaseAddressGuid HobLib PL011UartLib Note that FdtPL011SerialPortLib remains in use (just not via BaseDebugLibSerialPort); for instance by MdeModulePkg/Universal/SerialDxe, which produces the SerialIo protocol, underlying the UEFI console. The ArmVirtPkg DSC files will be switched to the new library instances in a separate patch. This patch is worth viewing with "git show --find-copies-harder".

* ArmVirtPkg: introduce DebugLibFdtPL011Uart Flash instanceLaszlo Ersek2023-10-264-0/+555
Introduce three new DebugLib instances, forked from MdePkg/Library/BaseDebugLibSerialPort. All three instances rely on PL011UartLib rather than SerialPortLib so that they can customize the PL011 UART that the debug messages are written to. All three instances direct the debug output to the first such PL011 UART that *differs* from the one specified in the Device Tree's /chosen node's "stdout-path" property. From these, DebugLibFdtPL011UartFlash mirrors EarlyFdtPL011SerialPortLib: it parses the initial Device Tree, and initializes the UART -- a UART different from EarlyFdtPL011SerialPortLib's -- for every message written. Suitable for SEC, PEI_CORE, PEIM. (Note that OVMF uses a similar set of dedicated DebugLib instances (PlatformDebugLibIoPort) for logging to the (x86-only) isa-debugcon device from various firmware phases.) The contexts in which these DebugLib instances run are identical to those in which the corresponding SerialPortLib instances run. The particular original dependency chain is BaseDebugLibSerialPort (SEC, PEI_CORE, PEIM) EarlyFdtPL011SerialPortLib PcdDeviceTreeInitialBaseAddress FdtSerialPortAddressLib PL011UartLib and the new dependency chain is DebugLibFdtPL011UartFlash (SEC, PEI_CORE, PEIM) PcdDeviceTreeInitialBaseAddress FdtSerialPortAddressLib PL011UartLib Note that EarlyFdtPL011SerialPortLib remains in use (just not via BaseDebugLibSerialPort), namely for direct SerialPortLib calls from SEC, PEI_CORE, PEIM. See for example commit 56035d1c8b25 ("ArmPlatformPkg/PrePeiCore: Print the firmware version early in boot", 2022-10-25). The ArmVirtPkg DSC files will be switched to the new library instances in a separate patch. This patch is worth viewing with "git show --find-copies-harder".
