multiple Arm platforms: set WritePolicyValid for all cache types

acpiview complains: ERROR: On Arm based systems, all cache properties must be provided in the cache type structure. Missing 'Write Policy Valid' flag. ACPI specification says: > Set to 1 if the write policy attribute described is valid.

Platform/RaspberryPi: Update for IORT revision macro renaming

2022-07-29T18:38:45+00:00

The IORT Specification E.d updates the IORT table revision to 5. To reflect this change the IORT header file has been updated to rename the EFI_ACPI_IO_REMAPPING_TABLE_REVISION macro which was at Rev 0 to EFI_ACPI_IO_REMAPPING_TABLE_REVISION_00. Therefore, update the usage of EFI_ACPI_IO_REMAPPING_TABLE_REVISION macro in the IORT table for RaspberryPi platform to EFI_ACPI_IO_REMAPPING_TABLE_REVISION_00.

Platform/RaspberryPi: Add 'clock-frequency' property for miniuart

2022-02-08T16:54:47+00:00

Describe the miniuart clock frequency in a _DSD property, so that it can be read from the Linux driver [1] The miniuart clock frequency is the core clock frequency on the Raspberry Pi. It can be modified by the user using the 'core_freq' property in the config.txt file. So, we fetch it from the underlying Raspberry Pi firmware.

Platform/RaspberryPi: Remove TypeTranslation attribute

The MMIO host bridge window isn't translated as both the primary and secondary side are MMIO. So remove the incorrect TypeTranslation attribute. Signed-off-by: Mark Kettenis Reviewed-by: Ard Biesheuvel

Platform/RaspberryPi/RPi4: Add _DSM ACPI method for 32-bit MMIO xHCI access

2021-09-01T17:29:58+00:00

With the upcoming release of Windows 11, Microsoft has introduced a new USB Device-Specific Method (_DSM) function to enforce 64-bit xHCI registers to be accessed through two sequential 32-bit requests. The new function (Query controller register access type - Function 6) is documented at: https://docs.microsoft.com/en-us/windows-hardware/drivers/bringup/usb-device-specific-method---dsm- Support for this feature is required on the Raspberry Pi 4 where there is a bug/limitation in the xHCI stack that prevents full range 64-bit access from working correctly. It should be noted that an equivalent for this _DSM is not required on Linux, as 64-bit xHCI register access is already broken down into 2x32-bit by the drivers there. With this _DSM, and unlike what is the case for Windows 10, Windows 11 can now be installed on the Raspberry Pi 4 without having to alter any of the installation files, as we were able to validate using the latest Windows 11 Build 22000 Insider image.

Platform/RaspberryPi: Add Linux quirk support

2021-08-22T13:55:32+00:00

Linux, for the time being has refused to support the Arm standard SMCCC for PCIe configuration. Instead they want to continue to maintain per device "quirks". As the RPI isn't really ECAM this is a bit more involved because the MCFG can't really describe the root port+config registers situation. Further platforms which support the SMCCC shouldn't have a MCFG, so we need an additional way to tell linux what it needs to know about this platform.

Platform/RaspberryPi: Add PCIe SSDT

2021-08-22T13:54:45+00:00

Since we plan on toggling between XHCI and PCI the PCI root needs to be in its own SSDT. This is all thats needed of UEFI. The SMC conduit is provided directly to the running OS. When the OS detects this PCIe port on a machine without a MCFG it attempts to connect to the SMC conduit. The RPi definition doesn't have any power mgmt, and only provides a description of the root port. Signed-off-by: Jeremy Linton Tested-by: Jared McNeill

Platform/RaspberryPi: Break XHCI into its own SSDT

2021-08-22T13:54:38+00:00

Lets prepare to switch between XHCI and PCI by moving the XHCI definition into its own SSDT. That way we can select it based on the menu settings. The resource producer/consumer flag is also corrected. Reviewed-by: Andrei Warkentin Signed-off-by: Jeremy Linton Tested-by: Jared McNeill

Platform/RaspberryPi/RPi4: Fix non-standard ACPI CIDs

Remove non-standard RPI ACPI _CIDs that are not needed. This also fixes the FWTS failure reported in https://github.com/pftf/RPi4/issues/67 The windows drivers at https://github.com/raspberrypi/windows-drivers are still able to match the ACPI objects using the HIDs which are supported in the drivers, with these two recent changes needed: 6469702898789e555c6947e50216a3f79e0ddeb9 and 5c5e2742b4c983b3001c473b168b0dae2fcba0c2 Cc: Leif Lindholm Cc: Ard Biesheuvel Cc: Pete Batard Cc: Andrei Warkentin Cc: Mario Bălănică Signed-off-by: Samer El-Haj-Mahmoud Tested-by: Mario Bălănică Reviewed-by: Sunny Wang Tested-by: Sunny Wang Reviewed-by: Andrei Warkentin

Platform/RaspberryPi: Enable Bluetooth and UART in Windows OS

2021-06-12T20:04:08+00:00

This change is based on edk2-platforms-raspberrypi-pl011-bth-noflow.diff in https://github.com/worproject/RPi-Bluetooth-Testing/ with the modifications and additional changes below for enabling Bluetooth and serial port (Mini UART) in Windows IOT. - Remove RPIQ connection for BT_ON/OFF in Uart.asl because it is useless. The firmware already turns on the Bluetooth by default. - Move the GPIO pin muxing stuff from Uart.asl to ConfigDxe driver. Testing Done: - Successfully booted Windows Windows 10 IOT (20279.1) on SD (made by WOR) with the RPi-Windows-Drivers release ver 0.5 downloaded from https://github.com/worproject/RPi-Windows-Drivers/releases and checked that both Bluetooth and serial port (Mini UART) can work fine. - Successfully booted VMware ESXi-Arm Fling v1.3 with only serial console connection (PL011 UART).
