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: Add ImagePropertiesRecordLib Instance

2023-12-01T08:07:31+00:00

ImagePropertiesRecordLib is used by DxeMain and PiSmmCore, so it needs to be added to most platforms. Signed-off-by: Taylor Beebe Cc: Ard Biesheuvel Cc: Leif Lindholm Cc: Jeremy Linton

RaspberryPi: Platform Build: Resolving newly introduced dependency

2022-08-16T17:53:14+00:00

The new changes in SecureBootVariableLib brought in a new dependency of PlatformPKProtectionLib. This change added the new library instance from SecurityPkg to resolve RaspberryPi platforms build. Signed-off-by: Kun Qin Reviewed-by: Jeremy Linton

RaspberryPi: Add VariableFlashInfoLib

2022-05-19T03:46:19+00:00

REF:https://bugzilla.tianocore.org/show_bug.cgi?id=3479 Adds an instance for the library class VariableFlashInfoLib that was recently introduced in MdeModulePkg. This change is made to allow the new variable driver to build that has a dependency on this library class and does not require any further platform changes.

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: 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: add SecureBootVariableLib resolution to various ARM platforms

2021-08-04T12:29:32+00:00

The edk2 patch SecurityPkg: Create library for setting Secure Boot variables. removes generic functions from SecureBootConfigDxe and places them into SecureBootVariableLib. This patch adds SecureBootVariableLib mapping for each ARM platform which uses SecureBootConfigDxe.

Platform/RaspberryPi: Dynamically build UARTs info in ACPI

2021-06-12T20:02:25+00:00

Changes: 1. Add code to ConfigDxe driver and AcpiTables module to dynamically build either Mini UART or PL011 UART info in ACPI. This also fixes the issue discussed in https://github.com/pftf/RPi4/issues/118. 2. Cleanup by moving duplicate Debug Port 2 table related defines and structures to a newly created header file (RpiDebugPort2Table.h). Testing Done: - Booted to UEFI shell and use acpiview command to check the result of the different UART settings in config.txt (enabling either Mini UART or PL011) and SPCR, DBG2 tables and device BTH0 are dynamically changed as expected.

Platform/RaspberryPi: Setup option for disabling Fast Boot

2021-04-15T18:48:51+00:00

This is a fix for https://github.com/pftf/RPi4/issues/114. Changes: 1. Add a setup option called BootPolicy and consume the setting during boot to decide whether to perform or skip ConnectAll. 2. The Default setting is set to Full discovery because it is not worth enabling Fast boot by default on RaspberryPi systems. Enabling it just saves boot time about 1 second, but caused a lot of issues. Testing Done: - Booted to Standalone UEFI shell on SD card and use drivers command to check the result with Fast Boot and Full discovery settings. Then, child/device handles are created as expected. Note and to-do items: - The root cause looks like that boot loaders and some tools like grub and iPXE haven't supported selective connect/Fast boot. However, system firmware should still provide a setup option for user to enable Fast boot with old version boot loaders and tools, which is why we proposed this change. We will also report this issue to boot loader and tool vendors/open source GitHubs. - We will add more options for connecting specific type devices so that we can still have the shortest boot time for all use cases.
