Platform/RaspberryPi: Give the user control over the XHCI mailbox

2024-03-11T14:18:22+00:00

It's a complete tossup whether removing the mailbox call after we have set up the XHCI works for a given kernel+distro in DT mode. So lets give users who want to try DT the option of flipping this on/off. Users that don't want to have to deal with DT, can use ACPI. Signed-off-by: Jeremy Linton Reviewed-by: Ard Biesheuvel

Platform/RaspberryPi: Cleanup menu visibility

2024-03-11T14:16:23+00:00

Lets allow some of these options to change when the system is in ACPI+DT mode. Plus the fan temp should be disabled when ACPI isn't enabled. Signed-off-by: Jeremy Linton Reviewed-by: Ard Biesheuvel

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: Normal memory should not be marked as uncached

2021-10-19T07:22:17+00:00

The EFI spec seems to indicate that the EFI uncacheable attribute should be mapped to device memory rather than normal-nc. This means that the UEFI mem attribute for the >3G ram doesn't match the remainder of the RAM in the machine. So, lets remove the uncacheable attribute to make it more consistent.

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: Add XHCI/PCI selection menu

2021-08-22T13:54:28+00:00

Arm has standardized a PCI SMC conduit that can be used to access the PCI config space in a standardized way. This functionality doesn't yet exist in many OS/Distro's. Lets add another advanced config item that allows the user to toggle between presenting the XHCI on the base RPi4 as a platform device, or presenting this newer PCIe conduit. The CM4 doesn't have an attached XHCI controller soldered to the PCIe, so PCIe mode is the default.

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).
