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.

Revert "Platform/RaspberryPi: Setup option for disabling Fast Boot"

2021-08-03T16:37:04+00:00

This reverts commit efdc159ef7c9f15581a0f63d755a1530ff475156. This commit is not longer required as Boot Discovery Policy has been implemented for Raspberry Pi.

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.

Platform/RaspberryPi: User control of eMMC2 DMA

2021-02-20T14:37:20+00:00

DMA translation on the eMMC2 vary based on SoC, and this is made worse by the poor _DMA support in Linux. For now the "safe" option is to simply run the eMMC2 controller in PIO mode. More advanced users or !Linux operating systems may choose to enable this to gain a perf boost. Signed-off-by: Jeremy Linton Reviewed-by: Pete Batard Reviewed-by: Andrei Warkentin

Platform/RaspberryPi: Add entry for user fan control

2020-09-01T12:11:30+00:00

Add a menu item that allows the user to enable GPIO based fan control via SSDT and the previous NameObj replacement commit. This should only be seen/enabled on RPI4 because that is what its been tested with. Given GPIO pin current limitations its likely that a bit of additional circuitry is required to drive a fan, and the GPIO high/low signal can only be used as a enable/disable signal. A search for "rpi npn gpio fan" or similar should turn up some hits for how to do this. Alternatively there are some commercial boards (FAN SHIM) which operate via simple GPIO control.
