This series aims at bringing the Raspberry Pi 4 platform to a state where its firmware can actually be used with Linux OSes
For instance, we have tested installation of vanilla Debian 10.2 on a USB 3.0 flash drive with a UEFI firmware built with these patches and, notwhistanding the lack of NIC or SD support (that have to do with these drivers not being included/finalized in the current Debian kernel), found that the system could be installed and could run without trouble. A few caveats are however required to achieve this: * If using the serial console, the platform UART should be set to PL011 rather than miniUART, as the miniUART baudrate is altered when the CPU throttles. * ACPI needs to be enforced over Device Tree, with some additional limitations regarding the maximum amount of RAM reported (3 GB max) due to DMA. This series effectively introduces two new build flags (PL011_ENABLE, ACPI_BASIC_MODE_ENABLE) to deal with the above. The rest of the series has mostly to do with ACPI improvements to make the above possible by: * Harmonizing and cleaning up existing ACPI sources * Using full aslc code for FADT, SPCR and DBG2 * Adding an XHCI table as well as a dummy MCFG table (the latter only being added to suppress a warning from the kernel about missing MCFG, since PCIe for that platform is not ECAM compliant) Andrei Warkentin (1): Platform/RPi4: Add XHCI and MCFG ACPI tables Ard Biesheuvel (1): Platform/RPi4: Add ACPI basic mode build option Pete Batard (4): Platform/RPi4: Clean up ACPI definitions Platform/RPi4: Improve FADT ACPI table generation Platform/RPi4: Improve SPCR and DBG2 ACPI table generation Platform/RPi4: Add switch to select between PL011 and miniUART Platform/RaspberryPi/Library/PlatformLib/PlatformLib.inf | 3 + Platform/RaspberryPi/Library/PlatformLib/RaspberryPiMem.c | 8 ++ Platform/RaspberryPi/RPi4/AcpiTables/AcpiTables.h | 12 +- Platform/RaspberryPi/RPi4/AcpiTables/AcpiTables.inf | 9 +- Platform/RaspberryPi/RPi4/AcpiTables/Csrt.aslc | 42 +++--- Platform/RaspberryPi/RPi4/AcpiTables/Dbg2.aslc | 110 +++++++++++++-- Platform/RaspberryPi/RPi4/AcpiTables/Dsdt.asl | 1 + Platform/RaspberryPi/RPi4/AcpiTables/Fadt.aslc | 104 +++++++++++---- Platform/RaspberryPi/RPi4/AcpiTables/Gtdt.aslc | 30 ++--- Platform/RaspberryPi/RPi4/AcpiTables/Madt.aslc | 11 +- Platform/RaspberryPi/RPi4/AcpiTables/Mcfg.aslc | 81 +++++++++++ Platform/RaspberryPi/RPi4/AcpiTables/Pep.asl | 4 +- Platform/RaspberryPi/RPi4/AcpiTables/Pep.c | 6 +- Platform/RaspberryPi/RPi4/AcpiTables/Pep.h | 8 +- Platform/RaspberryPi/RPi4/AcpiTables/Spcr.asl | 48 ------- Platform/RaspberryPi/RPi4/AcpiTables/Spcr.aslc | 101 ++++++++++++++ Platform/RaspberryPi/RPi4/AcpiTables/Uart.asl | 6 +- Platform/RaspberryPi/RPi4/AcpiTables/Xhci.asl | 140 ++++++++++++++++++++ Platform/RaspberryPi/RPi4/RPi4.dsc | 29 ++++ Platform/RaspberryPi/RPi4/RPi4.fdf | 7 + Platform/RaspberryPi/RPi4/Readme.md | 52 ++++++-- Platform/RaspberryPi/RaspberryPi.dec | 3 + 22 files changed, 657 insertions(+), 158 deletions(-) create mode 100644 Platform/RaspberryPi/RPi4/AcpiTables/Mcfg.aslc delete mode 100644 Platform/RaspberryPi/RPi4/AcpiTables/Spcr.asl create mode 100644 Platform/RaspberryPi/RPi4/AcpiTables/Spcr.aslc create mode 100644 Platform/RaspberryPi/RPi4/AcpiTables/Xhci.asl -- 2.21.0.windows.1 -=-=-=-=-=-=-=-=-=-=-=- Groups.io Links: You receive all messages sent to this group.
