am65x build issues
by Jan Kiszka 01 May '20

01 May '20

Hi all, I've noticed that building am65x_evm_a53_defconfig causes the dtbs to be built twice, once for the main u-boot and once for the spl. This is because of an extra dependency in mach-k3/config_secure.mk added by 508369672ca3. Why should the produced dtbs depend on the target that produces them? Why not simply this? diff --git a/arch/arm/mach-k3/config_secure.mk b/arch/arm/mach-k3/config_secure.mk index 6d63c57665..cbe9b684fb 100644 --- a/arch/arm/mach-k3/config_secure.mk +++ b/arch/arm/mach-k3/config_secure.mk @@ -34,11 +34,8 @@ MKIMAGEFLAGS_u-boot.img_HS = -f auto -A $(ARCH) -T firmware -C none -O u-boot \ -n "U-Boot $(UBOOTRELEASE) for $(BOARD) board" -E \ $(patsubst %,-b arch/$(ARCH)/dts/%.dtb_HS,$(subst ",,$(CONFIG_OF_LIST))) -OF_LIST_TARGETS = $(patsubst %,arch/$(ARCH)/dts/%.dtb,$(subst ",,$(CONFIG_OF_LIST))) -$(OF_LIST_TARGETS): dtbs - u-boot-nodtb.bin_HS: u-boot-nodtb.bin FORCE $(call if_changed,k3secureimg) -u-boot.img_HS: u-boot-nodtb.bin_HS u-boot.img $(patsubst %.dtb,%.dtb_HS,$(OF_LIST_TARGETS)) FORCE +u-boot.img_HS: u-boot-nodtb.bin_HS u-boot.img dtbs FORCE $(call if_changed,mkimage) Disclaimer: I didn't actually test the HS path, just the unsigned build.

[RFC 0/7] rockchip: Add PHY drivers
by Jagan Teki 30 Apr '20

30 Apr '20

This patch add support for USB2PHY and PCIe PHY driver on rockchip platform and tested the same in rk3399. Basic code is referenced from Linux, hence all the license SPDX are reused. The reason behind sending this as RFC is PHY devices for u2phy, pcie_phy nodes are unable to get via Generic PHY framework. The observed reasons are 1) u2phy is not part of root node. 2) pcie_phy is not part of root node and also parent is of non-PHY type. This is sample PHY provider topology that Generic PHY is failed to get PHY device. /{ grf: syscon@ff770000 { compatible = "rockchip,rk3399-grf", "syscon", "simple-mfd"; reg = <0x0 0xff770000 0x0 0x10000>; #address-cells = <1>; #size-cells = <1>; u2phy0: usb2-phy@e450 { compatible = "rockchip,rk3399-usb2phy"; reg = <0xe450 0x10>; clocks = <&cru SCLK_USB2PHY0_REF>; clock-names = "phyclk"; #clock-cells = <0>; clock-output-names = "clk_usbphy0_480m"; status = "disabled"; u2phy0_host: host-port { #phy-cells = <0>; interrupts = <GIC_SPI 27 IRQ_TYPE_LEVEL_HIGH 0>; interrupt-names = "linestate"; status = "disabled"; }; u2phy0_otg: otg-port { #phy-cells = <0>; interrupts = <GIC_SPI 103 IRQ_TYPE_LEVEL_HIGH 0>, <GIC_SPI 104 IRQ_TYPE_LEVEL_HIGH 0>, <GIC_SPI 106 IRQ_TYPE_LEVEL_HIGH 0>; interrupt-names = "otg-bvalid", "otg-id", "linestate"; status = "disabled"; }; }; pcie_phy: pcie-phy { compatible = "rockchip,rk3399-pcie-phy"; clocks = <&cru SCLK_PCIEPHY_REF>; clock-names = "refclk"; #phy-cells = <1>; resets = <&cru SRST_PCIEPHY>; drive-impedance-ohm = <50>; reset-names = "phy"; status = "disabled"; }; }; So, this series moved these nodes as part of root to make it work but of course any suggestions on this will be taken into consideration. Any inputs? Jagan.

[PATCH v2 0/7] x86: efi: Add a 64-bit coreboot payload
by Simon Glass 30 Apr '20

30 Apr '20

This series creates a new 64-bit 'coreboot64' build which can be launched from coreboot. It uses SPL to effect the jump to 64-bit mode. This was done in an attempt to get the Ubuntu FirmwareTestSuite[1] working. Unfortunately the latest version shows a splash screen and hangs, perhaps due to some missing EFI support. [1] https://wiki.ubuntu.com/FirmwareTestSuite Changes in v2: - Add a new patch to indicate 32/64-bit in bdinfo Simon Glass (7): x86: Allow building an SPL image for coreboot x86: Move work-around out of cpu_jump_to_64bit_uboot() x86: Update SPL for coreboot x86: cbfs: Drop unwanted declaration x86: coreboot: Allow building an SPL image x86: Add an indication of 32/64-bit to bdinfo x86: Add a 64-bit coreboot build Makefile | 6 ++++ arch/x86/cpu/Makefile | 4 ++- arch/x86/cpu/coreboot/Kconfig | 1 + arch/x86/cpu/coreboot/Makefile | 8 ++++- arch/x86/cpu/coreboot/coreboot.c | 3 +- arch/x86/cpu/coreboot/coreboot_spl.c | 12 +++++++ arch/x86/cpu/i386/cpu.c | 10 ------ arch/x86/cpu/intel_common/Makefile | 2 ++ arch/x86/cpu/x86_64/cpu.c | 2 ++ arch/x86/dts/coreboot-u-boot.dtsi | 18 +++++++++++ arch/x86/lib/spl.c | 23 ++++++++++--- board/coreboot/coreboot/MAINTAINERS | 7 ++++ cmd/bdinfo.c | 1 + configs/coreboot64_defconfig | 48 ++++++++++++++++++++++++++++ doc/board/coreboot/coreboot.rst | 10 ++++++ include/cbfs.h | 2 +- 16 files changed, 139 insertions(+), 18 deletions(-) create mode 100644 arch/x86/cpu/coreboot/coreboot_spl.c create mode 100644 arch/x86/dts/coreboot-u-boot.dtsi create mode 100644 configs/coreboot64_defconfig -- 2.26.2.303.gf8c07b1a785-goog

[PATCH v1 00/35] dm: Add programmatic generation of ACPI tables (part B)
by Simon Glass 30 Apr '20

30 Apr '20

NOTE: I have resent this as v1 to avoid confusion This is split from the original series in an attempt to get things applied in chunks. This part includes: - writing basic ACPI code for integers, strings, names, packages - writing descriptors for GPIO, I2C, interrupts, SPI - writing code to enable/disable ACPI peripherals via GPIOs - writing SSDT and DSDT tables - additional ways to determine ACPI device names Much of this code is taken from coreboot and I have tried to avoid changing the original code for no reason. Changes include: - splitting the acpi_dp functions into their own file - adding tests - adding (lots of) comments - using a context pointer instead of global variables - tidying up some code where couldn't resist (e.g. acpigen_emit_namestring()) Changes in v1: - Capitalise ACPI_OPS_PTR - Split into more patches for review - Add tests - Fix 'the an' typo - Move header definitions into this patch - Update sandbox driver slightly for testing - Switch parameter order of _acpi_fill_ssdt() and make it static - Fix 'sentinal' and 'METHOD_FILL_SDDT' typos - Correct the commit subject - Generalise the ACPI function recursion with acpi_recurse_method() - Generalise the ACPI function recursion with acpi_recurse_method() - Use OEM_TABLE_ID instead of ACPI_TABLE_CREATOR - Update ACPI_DSTATUS enum - Generalise the ACPI function recursion with acpi_recurse_method() - Use acpi,ddn instead of acpi,desc - Rename to acpi_device_infer_name() - Update newly created sandbox tests Simon Glass (35): dm: core: Add an ACPI name for the root node acpi: Add a function to get a device path and scope acpi: Add a way to check device status irq: Add a method to convert an interrupt to ACPI acpi: Support generation of ACPI code acpi: Support generation of interrupt descriptor gpio: Add a method to convert a GPIO to ACPI acpi: Support string output acpi: Support generation of GPIO descriptor acpi: Support generation of a GPIO/irq for a device acpi: Support generation of I2C descriptor acpi: Support generation of SPI descriptor acpigen: Support writing a length acpigen: Support writing a package acpi: Support writing an integer acpi: Support writing a string acpi: Support writing a name acpi: Support writing a UUID acpi: Support writing Device Properties objects via _DSD acpi: Support writing a GPIO acpi: Support copying properties from device tree to ACPI acpi: Add support for various misc ACPI opcodes acpi: Add support for writing a Power Resource acpi: Add support for writing a GPIO power sequence acpi: Add support for a generic power sequence acpi: Add support for SSDT generation x86: acpi: Move MADT down a bit acpi: Record the items added to SSDT acpi: Support ordering SSDT data by device x86: Allow devices to write an SSDT acpi: Add support for DSDT generation x86: Allow devices to write to DSDT pci: Avoid a crash in device_is_on_pci_bus() dm: acpi: Enhance acpi_get_name() acpi: Add an acpi split command arch/sandbox/dts/test.dts | 14 +- arch/x86/lib/acpi_table.c | 75 ++- cmd/acpi.c | 15 +- doc/device-tree-bindings/chosen.txt | 9 + doc/device-tree-bindings/device.txt | 13 + drivers/core/acpi.c | 207 ++++++- drivers/core/root.c | 13 + drivers/gpio/gpio-uclass.c | 21 + drivers/gpio/sandbox.c | 78 +++ drivers/i2c/sandbox_i2c.c | 1 + drivers/misc/irq-uclass.c | 18 +- drivers/misc/irq_sandbox.c | 16 + drivers/rtc/sandbox_rtc.c | 11 + drivers/spi/sandbox_spi.c | 1 + include/acpi/acpi_device.h | 400 +++++++++++++ include/acpi/acpi_dp.h | 283 +++++++++ include/acpi/acpi_table.h | 6 + include/acpi/acpigen.h | 347 +++++++++++ include/asm-generic/gpio.h | 27 + include/dm/acpi.h | 63 ++ include/dm/device.h | 2 +- include/irq.h | 43 ++ include/spi.h | 4 +- include/test/ut.h | 17 + lib/acpi/Makefile | 3 + lib/acpi/acpi_device.c | 808 ++++++++++++++++++++++++++ lib/acpi/acpi_dp.c | 395 +++++++++++++ lib/acpi/acpigen.c | 475 +++++++++++++++ test/dm/Makefile | 2 + test/dm/acpi.c | 277 ++++++++- test/dm/acpi_dp.c | 510 ++++++++++++++++ test/dm/acpigen.c | 861 ++++++++++++++++++++++++++++ test/dm/gpio.c | 62 ++ test/dm/irq.c | 23 + test/dm/pci.c | 14 + 35 files changed, 5081 insertions(+), 33 deletions(-) create mode 100644 include/acpi/acpi_device.h create mode 100644 include/acpi/acpi_dp.h create mode 100644 include/acpi/acpigen.h create mode 100644 lib/acpi/acpi_device.c create mode 100644 lib/acpi/acpi_dp.c create mode 100644 lib/acpi/acpigen.c create mode 100644 test/dm/acpi_dp.c create mode 100644 test/dm/acpigen.c -- 2.26.2.303.gf8c07b1a785-goog
