[PATCH v11 00/15] FWU: Add FWU Multi Bank Update feature support
by Sughosh Ganu 01 Nov '22

01 Nov '22

The patchset adds support for the FWU Multi Bank Update[1] feature. Certain aspects of the Dependable Boot[2] specification have also been implemented. The FWU multi bank update feature is used for supporting multiple sets(also called banks) of firmware image(s), allowing the platform to boot from a different bank, in case it fails to boot from the active bank. This functionality is supported by keeping the relevant information in a structure called metadata, which provides information on the images. Among other parameters, the metadata structure contains information on the currect active bank that is being used to boot image(s). Functionality is being added to work with the UEFI capsule driver in u-boot. The metadata is read to gather information on the update bank, which is the bank to which the firmware images would be flashed to. On a successful completion of the update of all components, the active bank field in the metadata is updated, to reflect the bank from which the platform will boot on the subsequent boots. Currently, the feature is being enabled on the STM32MP157C-DK2 and Synquacer boards. The DK2 board boots a FIP image from a uSD card partitioned with the GPT partioning scheme, while the Synquacer board boots a FIP image from a MTD partitioned SPI NOR flash device. This feature also requires changes in a previous stage of bootloader, which parses the metadata and selects the bank to boot the image(s) from. Support has being added in tf-a(BL2 stage) for the STM32MP157C-DK2 board to boot the active bank images. These changes have been merged to the upstream tf-a repository. The patch for adding a python test for the feature has been developed, and was sent in the version 5 of the patches[3]. However, the test script depends on adding support for the feature on MTD SPI NOR devices, and that is being done as part of the Synquacer patches. Hence these set of patches do not have the test script for the feature. That will be added through the patches for adding support for the feauture on Synquacer platform.

[PATCH v2 1/2] timer: sti: convert sti-timer to arm a9 global timer
by William Zhang 31 Oct '22

STI timer is actually ARM Cortex A9 global timer. Convert the driver to use generic global timer name and make it consistent with Linux kernel global timer driver. This also allows any A9 based device to use this driver.

[PATCH v2 0/3] arm: bcmbca: move bcm6753 support under CONFIG_ARCH_BCMBCA
by William Zhang 31 Oct '22

31 Oct '22

Sorry for another version of patch series with some minor updates. Please see the change log and specific patch for details. BCM6753 is essentially same as the main chip BCM6855 with different SKU number. It is part of the Broadcom BCA (Broadband Carrier Access origin) chipset family. BCM6753 was originally added by Philippe before Broadcom started to upstream the support for BCMBCA SoCs. The ARM based broadband SoC family is now supported under the unified ARCH_BCMBCA config. This patch series migrate the BCM6753 support under the config of ARCH_BCMBCA and BCM6855. This patch series need to apply on top of my previous patch series [1]. This concludes the addition of BCA SoC support to u-boot at least for now.

[PATCH v2] arm: bcmbca: add bcm63138 SoC support
by William Zhang 31 Oct '22

31 Oct '22

BCM63138 is an ARM A9 based DSL Broadband SoC. It is part of the BCA (Broadband Carrier Access origin) chipset family so it's added under ARCH_BCMBCA platform. This initial support includes a bare-bone implementation and dts with CPU subsystem, memory, ARM A9 global timer and Broadcom uart. This SoC is supported in the linux-next git repository so the dts and dtsi files are stripped down version of linux copies with mininum blocks needed by u-boot. The u-boot image can be loaded from flash or network to the entry point address in the memory and boot from there to the console. This patch applies on top of the my previous patch [1].

[PATCH v2 0/5] arm: bcmbca: add basic support for Broadcom BCA SoCs

Now that the ARCH_BCMBCA architecture and its first SoC BCM47622 are supported in u-boot 2022.07, this patch series add the basic support for following BCA chips under ARCH_BCMBCA: BCM63178, BCM6846, BCM6878, BCM6756 and BCM63148. We expect to send additional patches for more BCMBCA SoCs in the near future. Changes in v2: - Move COUNTER_FREQUENCY to bcm63178 defconfig - Move COUNTER_FREQUENCY to bcm6846 defconfig - Move COUNTER_FREQUENCY to bcm6878 defconfig - Move COUNTER_FREQUENCY to bcm6756 defconfig - Move COUNTER_FREQUENCY to bcm63148 defconfig William Zhang (5): arm: bcmbca: add bcm63178 SoC support arm: bcmbca: add bcm6846 SoC support arm: bcmbca: add bcm6878 SoC support arm: bcmbca: add bcm6756 SoC support arm: bcmbca: add bcm63148 SoC support MAINTAINERS | 9 +- arch/arm/dts/Makefile | 10 ++ arch/arm/dts/bcm63148.dtsi | 103 ++++++++++++++++++++ arch/arm/dts/bcm63178.dtsi | 120 +++++++++++++++++++++++ arch/arm/dts/bcm6756.dtsi | 130 +++++++++++++++++++++++++ arch/arm/dts/bcm6846.dtsi | 103 ++++++++++++++++++++ arch/arm/dts/bcm6878.dtsi | 111 +++++++++++++++++++++ arch/arm/dts/bcm963148.dts | 30 ++++++ arch/arm/dts/bcm963178.dts | 30 ++++++ arch/arm/dts/bcm96756.dts | 30 ++++++ arch/arm/dts/bcm96846.dts | 30 ++++++ arch/arm/dts/bcm96878.dts | 30 ++++++ arch/arm/mach-bcmbca/Kconfig | 42 +++++++- arch/arm/mach-bcmbca/Makefile | 5 + arch/arm/mach-bcmbca/bcm63148/Kconfig | 17 ++++ arch/arm/mach-bcmbca/bcm63148/Makefile | 5 + arch/arm/mach-bcmbca/bcm63178/Kconfig | 17 ++++ arch/arm/mach-bcmbca/bcm63178/Makefile | 5 + arch/arm/mach-bcmbca/bcm6756/Kconfig | 17 ++++ arch/arm/mach-bcmbca/bcm6756/Makefile | 5 + arch/arm/mach-bcmbca/bcm6846/Kconfig | 17 ++++ arch/arm/mach-bcmbca/bcm6846/Makefile | 5 + arch/arm/mach-bcmbca/bcm6878/Kconfig | 17 ++++ arch/arm/mach-bcmbca/bcm6878/Makefile | 5 + board/broadcom/bcmbca/Kconfig | 35 +++++++ configs/bcm963148_defconfig | 23 +++++ configs/bcm963178_defconfig | 23 +++++ configs/bcm96756_defconfig | 23 +++++ configs/bcm96846_defconfig | 23 +++++ configs/bcm96878_defconfig | 23 +++++ include/configs/bcm963148.h | 11 +++ include/configs/bcm963178.h | 11 +++ include/configs/bcm96756.h | 11 +++ include/configs/bcm96846.h | 11 +++ include/configs/bcm96878.h | 11 +++ 35 files changed, 1095 insertions(+), 3 deletions(-) create mode 100644 arch/arm/dts/bcm63148.dtsi create mode 100644 arch/arm/dts/bcm63178.dtsi create mode 100644 arch/arm/dts/bcm6756.dtsi create mode 100644 arch/arm/dts/bcm6846.dtsi create mode 100644 arch/arm/dts/bcm6878.dtsi create mode 100644 arch/arm/dts/bcm963148.dts create mode 100644 arch/arm/dts/bcm963178.dts create mode 100644 arch/arm/dts/bcm96756.dts create mode 100644 arch/arm/dts/bcm96846.dts create mode 100644 arch/arm/dts/bcm96878.dts create mode 100644 arch/arm/mach-bcmbca/bcm63148/Kconfig create mode 100644 arch/arm/mach-bcmbca/bcm63148/Makefile create mode 100644 arch/arm/mach-bcmbca/bcm63178/Kconfig create mode 100644 arch/arm/mach-bcmbca/bcm63178/Makefile create mode 100644 arch/arm/mach-bcmbca/bcm6756/Kconfig create mode 100644 arch/arm/mach-bcmbca/bcm6756/Makefile create mode 100644 arch/arm/mach-bcmbca/bcm6846/Kconfig create mode 100644 arch/arm/mach-bcmbca/bcm6846/Makefile create mode 100644 arch/arm/mach-bcmbca/bcm6878/Kconfig create mode 100644 arch/arm/mach-bcmbca/bcm6878/Makefile create mode 100644 configs/bcm963148_defconfig create mode 100644 configs/bcm963178_defconfig create mode 100644 configs/bcm96756_defconfig create mode 100644 configs/bcm96846_defconfig create mode 100644 configs/bcm96878_defconfig create mode 100644 include/configs/bcm963148.h create mode 100644 include/configs/bcm963178.h create mode 100644 include/configs/bcm96756.h create mode 100644 include/configs/bcm96846.h create mode 100644 include/configs/bcm96878.h -- 2.37.1

[PATCH v2] video: dw_mipi_dsi: fix [hv]sync active vs back porch
by John Keeping 31 Oct '22

31 Oct '22

The wrong fields are pulled out of the timings here so the values programmed into the DSI_VID_HSA_LINES/DSI_VID_HBP_LINES and DSI_VID_VSA_LINES/DSI_VID_VBP_LINES registers are swapped. Use the right fields so that the correct values are programmed.
