[PATCH 0/3] rockchip: rk35xx: Fix writing to eMMC
by Jonas Karlman 03 Feb '24

03 Feb '24

Writing to eMMC using DDR52 mode does not work reliably or at all on RK356x and RK3588 boards. This series fixes this issue by changing RK356x and RK3588 boards to prefer use of the more reliably HS200 mode. This series depend on the series "rockchip: rk35xx: Sync device tree with linux v6.8-rc1" [1]. [1] https://patchwork.ozlabs.org/cover/1891669/ Jonas Karlman (3): rockchip: rk35xx: Remove use of eMMC DDR52 mode rockchip: rk356x: Enable eMMC HS200 mode rockchip: rk3588: Enable eMMC HS200 mode arch/arm/dts/rk3566-quartz64-a-u-boot.dtsi | 1 - arch/arm/dts/rk3566-quartz64-b-u-boot.dtsi | 1 - arch/arm/dts/rk3566-radxa-cm3-io-u-boot.dtsi | 1 - arch/arm/dts/rk3566-soquartz-u-boot.dtsi | 1 - arch/arm/dts/rk3568-lubancat-2-u-boot.dtsi | 1 - arch/arm/dts/rk3568-nanopi-r5s-u-boot.dtsi | 1 - arch/arm/dts/rk3568-odroid-m1-u-boot.dtsi | 1 - arch/arm/dts/rk3568-radxa-e25-u-boot.dtsi | 1 - arch/arm/dts/rk3568-rock-3a-u-boot.dtsi | 1 - arch/arm/dts/rk3588-rock-5b-u-boot.dtsi | 1 - arch/arm/dts/rk3588-turing-rk1-u-boot.dtsi | 1 - arch/arm/dts/rk3588s-rock-5a-u-boot.dtsi | 1 - configs/anbernic-rgxx3-rk3566_defconfig | 2 ++ configs/bpi-r2-pro-rk3568_defconfig | 2 ++ configs/evb-rk3568_defconfig | 2 ++ configs/evb-rk3588_defconfig | 2 ++ configs/lubancat-2-rk3568_defconfig | 2 ++ configs/nanopc-t6-rk3588_defconfig | 2 ++ configs/neu6a-io-rk3588_defconfig | 2 ++ configs/neu6b-io-rk3588_defconfig | 2 ++ configs/odroid-m1-rk3568_defconfig | 2 ++ configs/orangepi-5-plus-rk3588_defconfig | 2 ++ configs/quartz64-a-rk3566_defconfig | 2 ++ configs/quartz64-b-rk3566_defconfig | 2 ++ configs/quartzpro64-rk3588_defconfig | 2 ++ configs/radxa-cm3-io-rk3566_defconfig | 2 ++ configs/rock-3a-rk3568_defconfig | 2 ++ configs/rock5a-rk3588s_defconfig | 2 ++ configs/rock5b-rk3588_defconfig | 2 ++ configs/soquartz-blade-rk3566_defconfig | 2 ++ configs/soquartz-cm4-rk3566_defconfig | 2 ++ configs/soquartz-model-a-rk3566_defconfig | 2 ++ configs/turing-rk1-rk3588_defconfig | 2 ++ 33 files changed, 42 insertions(+), 12 deletions(-) -- 2.43.0

[PATCH 0/2] riscv: cpu: Add support for cv1800b SoC
by Kongyang Liu 03 Feb '24

03 Feb '24

This series add basic support for cv1800b SoC and enable dcache support. The cv1800b utilizes CSR instructions to manipulate the first and second bits in the MHCR register (0x7C1) to indicate the activation status of icache and dcache. As the icache and dcache are already enabled in the FSBL (first stage bootloader) provided by the vendor, and the U-Boot running in S-Mode is unable to manipulate CSR registers, support for operations related to enabling, disabling, or checking the status of the cache is not provided.

[PATCH v9 0/2] arm64: Add a build target for Flat Image Tree
by Simon Glass 02 Feb '24

02 Feb '24

Flat Image Tree (FIT) is a widely used file format for packaging a kernel and associated devicetree files[1]. It is not specific to any one bootloader, as it is supported by U-Boot, coreboot, Linuxboot, Tianocore and Barebox. This series adds support for building a FIT as part of the kernel build. This makes it easy to try out the kernel - just load the FIT onto your tftp server and it will run automatically on any supported arm64 board. The script is written in Python, since it is easy to build a FIT using the Python libfdt bindings. For now, no attempt is made to compress files in parallel, so building the 900-odd files takes a while, about 6 seconds with my testing. The series also includes a few minor clean-up patches. [1] https://github.com/open-source-firmware/flat-image-tree Changes in v9: - Move the compression control into Makefile.lib Changes in v8: - Drop compatible string in FDT node - Correct sorting of MAINTAINERS to before ARM64 PORT - Turn compress part of the make_fit.py comment in to a sentence - Add two blank lines before parse_args() and setup_fit() - Use 'image.fit: dtbs' instead of BUILD_DTBS var - Use '$(<D)/dts' instead of '$(dir $<)dts' - Add 'mkimage' details Documentation/process/changes.rst - Allow changing the compression used - Tweak cover letter since there is only one clean-up patch Changes in v7: - Drop the kbuild tag - Add Image as a dependency of image.fit - Drop kbuild tag - Add dependency on dtbs - Drop unnecessary path separator for dtbs - Rebase to -next Changes in v6: - Drop the unwanted .gz suffix Changes in v5: - Drop patch previously applied - Correct compression rule which was broken in v4 Changes in v4: - Use single quotes for UIMAGE_NAME Changes in v3: - Drop temporary file image.itk - Drop patch 'Use double quotes for image name' - Drop double quotes in use of UIMAGE_NAME - Drop unnecessary CONFIG_EFI_ZBOOT condition for help - Avoid hard-coding "arm64" for the DT architecture Changes in v2: - Drop patch previously applied - Add .gitignore file - Move fit rule to Makefile.lib using an intermediate file - Drop dependency on CONFIG_EFI_ZBOOT - Pick up .dtb files separately from the kernel - Correct pylint too-many-args warning for write_kernel() - Include the kernel image in the file count - Add a pointer to the FIT spec and mention of its wide industry usage - Mention the kernel version in the FIT description Simon Glass (2): arm64: Add BOOT_TARGETS variable arm64: boot: Support Flat Image Tree Documentation/process/changes.rst | 9 + MAINTAINERS | 7 + arch/arm64/Makefile | 11 +- arch/arm64/boot/.gitignore | 1 + arch/arm64/boot/Makefile | 6 +- scripts/Makefile.lib | 16 ++ scripts/make_fit.py | 291 ++++++++++++++++++++++++++++++ 7 files changed, 338 insertions(+), 3 deletions(-) create mode 100755 scripts/make_fit.py -- 2.43.0.rc2.451.g8631bc7472-goog

[PATCH 1/2] mx6sabresd: Fix U-Boot corruption after saving the environment
by Fabio Estevam 02 Feb '24

02 Feb '24

From: Fabio Estevam <festevam(a)denx.de> U-Boot binary has grown in such a way that it goes beyond the reserved area for the environment variables. Running "saveenv" and rebooting the board causes U-Boot to hang because of this overlap. Fix this problem by increasing the CONFIG_ENV_OFFSET. Also, to prevent this same problem to happen in the future, use CONFIG_BOARD_SIZE_LIMIT, which can detect the overlap in build-time. CONFIG_BOARD_SIZE_LIMIT is calculated as follows: CONFIG_BOARD_SIZE_LIMIT = CONFIG_ENV_OFFSET - u-boot-img.dtb offset CONFIG_BOARD_SIZE_LIMIT = 0xd000 - 69 * 1024 CONFIG_BOARD_SIZE_LIMIT = 781312 Signed-off-by: Fabio Estevam <festevam(a)denx.de> --- configs/mx6sabresd_defconfig | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) diff --git a/configs/mx6sabresd_defconfig b/configs/mx6sabresd_defconfig index a90efe4a7786..f19df607e7ae 100644 --- a/configs/mx6sabresd_defconfig +++ b/configs/mx6sabresd_defconfig @@ -9,7 +9,7 @@ CONFIG_SPL_LIBGENERIC_SUPPORT=y CONFIG_NR_DRAM_BANKS=1 CONFIG_SF_DEFAULT_SPEED=20000000 CONFIG_ENV_SIZE=0x2000 -CONFIG_ENV_OFFSET=0xC0000 +CONFIG_ENV_OFFSET=0xd0000 CONFIG_MX6QDL=y CONFIG_TARGET_MX6SABRESD=y CONFIG_DM_GPIO=y @@ -24,6 +24,8 @@ CONFIG_PCI=y CONFIG_FIT=y CONFIG_SPL_FIT_PRINT=y CONFIG_SPL_LOAD_FIT=y +CONFIG_HAS_BOARD_SIZE_LIMIT=y +CONFIG_BOARD_SIZE_LIMIT=781312 CONFIG_SUPPORT_RAW_INITRD=y CONFIG_USE_BOOTCOMMAND=y CONFIG_BOOTCOMMAND="run findfdt;mmc dev ${mmcdev};if mmc rescan; then if run loadbootscript; then run bootscript; else if run loadimage; then run mmcboot; else run netboot; fi; fi; else run netboot; fi" -- 2.34.1
