This series adds a new aarch64 machine to QEMU: i.MX 8M Plus EVK [1]. It allows for running Linux distributions such as Buildroot (freescale_imx8mpevk_defconfig) and Arch Linux [2] via direct kernel boot. U-Boot does not work yet. I plan to use this machine in CI and I also want to make it available to a bigger audience, so I propose to add it to QEMU. My goal would be to have it added for 10.0. For this, a Changelog entry could be added under https://wiki.qemu.org/ChangeLog/10.0 such as: * New board model "imx8mp-evk": i.MX 8M Plus Evaluation Kit
The series is structured as follows: The first three patches fix some issues in device models reused by the new machine. Patches 4-17 add the machine step by step which includes documentation. The last patch adds an I²C RTC which I'd like to use along with the new machine. I've based some code on existing one (see "Based on" in file headers) and I'm unsure how to handle the licensing and attribution correctly -- advice welcome. v3: * Pick up R-b tags * Add QTest testcase for the RS5C372 RTC (Phil) * Rephrase machine description (Peter) * Fix typos and confused sentence in machine documentation (Peter) * Use g_autofree for object names (Peter) * Clarify source of "cntfrq" CPU property (Peter) * Fix typo "g[e]neral purpose timers" in commit message (Peter) * Don't `default y if I2C_DEVICES` for hw/gpio/pca955* (Peter) * TYPE_FSL_IMX8M_PCIE_PHY: * Implement reset method (Peter) * Use named constant rather than risking undefined behavior (Peter) * Fix copy'n'paste typo in imx8mp_analog.c Open questions: * How to generate all zero boot rom file in a portable way (Peter) v2: * Rebase onto master, eliminating some patches from the series * Initialize ROM with memory_region_init_rom() (Zoltan) * Mark the machine as "Maintained" (Peter) * Do not select TEST_DEVICES (Peter) * Have separate sources for the two clock tree modules (Peter) * Make PCI devices attach to the correct bus (Peter) * Avoid adding documentation that is removed later (Zoltan) Instead, document Buildroot process in the first place and change it slightly. * Drop TCA6416 device model (Phil, Dmitrii) * Add pca955* Kconfig cleanup patch [1] https://www.nxp.com/design/design-center/development-boards-and-designs/8MPLUSLPD4-EVK [2] https://archlinuxarm.org/platforms/armv8/generic Bernhard Beschow (18): hw/usb/hcd-dwc3: Align global registers size with Linux hw/pci-host/designware: Prevent device attachment on internal PCIe root bus hw/gpio/pca955*: Move Kconfig switches next to implementations hw/arm: Add i.MX 8M Plus EVK board hw/arm/fsl-imx8mp: Implement clock tree hw/arm/fsl-imx8mp: Add SNVS hw/arm/fsl-imx8mp: Add USDHC storage controllers hw/arm/fsl-imx8mp: Add PCIe support hw/arm/fsl-imx8mp: Add GPIO controllers hw/arm/fsl-imx8mp: Add I2C controllers hw/arm/fsl-imx8mp: Add SPI controllers hw/arm/fsl-imx8mp: Add watchdog support hw/arm/fsl-imx8mp: Implement general purpose timers hw/arm/fsl-imx8mp: Add Ethernet controller hw/arm/fsl-imx8mp: Add USB support hw/arm/fsl-imx8mp: Add boot ROM hw/arm/fsl-imx8mp: Add on-chip RAM hw/rtc: Add Ricoh RS5C372 RTC emulation MAINTAINERS | 16 + docs/system/arm/imx8mp-evk.rst | 70 +++ docs/system/target-arm.rst | 1 + include/hw/arm/fsl-imx8mp.h | 285 +++++++++++ include/hw/misc/imx8mp_analog.h | 81 +++ include/hw/misc/imx8mp_ccm.h | 30 ++ include/hw/pci-host/designware.h | 7 + include/hw/pci-host/fsl_imx8m_phy.h | 28 ++ include/hw/timer/imx_gpt.h | 1 + include/hw/usb/hcd-dwc3.h | 2 +- hw/arm/fsl-imx8mp.c | 732 ++++++++++++++++++++++++++++ hw/arm/imx8mp-evk.c | 74 +++ hw/misc/imx8mp_analog.c | 160 ++++++ hw/misc/imx8mp_ccm.c | 175 +++++++ hw/pci-host/designware.c | 18 +- hw/pci-host/fsl_imx8m_phy.c | 98 ++++ hw/rtc/rs5c372.c | 236 +++++++++ hw/timer/imx_gpt.c | 25 + hw/usb/hcd-dwc3.c | 5 + tests/qtest/rs5c372-test.c | 43 ++ hw/arm/Kconfig | 24 + hw/arm/meson.build | 2 + hw/gpio/Kconfig | 8 + hw/misc/Kconfig | 14 +- hw/misc/meson.build | 2 + hw/pci-host/Kconfig | 3 + hw/pci-host/meson.build | 1 + hw/rtc/Kconfig | 5 + hw/rtc/meson.build | 1 + hw/rtc/trace-events | 4 + pc-bios/imx8mp-boot.rom | Bin 0 -> 258048 bytes pc-bios/meson.build | 1 + tests/qtest/meson.build | 1 + 33 files changed, 2143 insertions(+), 10 deletions(-) create mode 100644 docs/system/arm/imx8mp-evk.rst create mode 100644 include/hw/arm/fsl-imx8mp.h create mode 100644 include/hw/misc/imx8mp_analog.h create mode 100644 include/hw/misc/imx8mp_ccm.h create mode 100644 include/hw/pci-host/fsl_imx8m_phy.h create mode 100644 hw/arm/fsl-imx8mp.c create mode 100644 hw/arm/imx8mp-evk.c create mode 100644 hw/misc/imx8mp_analog.c create mode 100644 hw/misc/imx8mp_ccm.c create mode 100644 hw/pci-host/fsl_imx8m_phy.c create mode 100644 hw/rtc/rs5c372.c create mode 100644 tests/qtest/rs5c372-test.c create mode 100644 pc-bios/imx8mp-boot.rom -- 2.48.1
