[PATCH v1 1/1] Makefile.lib: Always rebuild DSDT
by Andy Shevchenko 09 Dec '23

09 Dec '23

The dsdt.asl is usually combined out of several files that are included in the main one. Whenever we change the content of any of such files, build system is not able to recognize them. Hence the easiest way is to force DSDT rebuild each time we run make.

[PATCH] dfu: add CONFIG_DFU_NAME_MAX_SIZE configuration
by Jaehoon Chung 07 Nov '23

[PATCH v3 0/9] New boards support: db845c and qcs404-evb
by Sumit Garg 11 Sep '23

11 Sep '23

Add support for two new boards db845c and qcs404-evb: - db845c is a 96boards compliant platform aka RB3 based on Qualcomm SDM845 SoC. - qcs404-evb is an evaluation board from Qualcomm based on QCS404 SoC. Both these platforms have one thing in common that u-boot is chain-loaded in 64-bit mode via Android Boot Loader (ABL) which is an EFI application. For further details on chain-loading refer to platform specific documentation: - doc/board/qualcomm/sdm845.rst - doc/board/qualcomm/qcs404.rst Changes in v3: - Add clocks re-initialization for UART and eMMC for qcs404-evb. - Pick up Ramon's review tag for patches 1-7. Changes in v2: - Added patch #1 to fix DT node overrides in starqltechn-uboot.dtsi. - Updated patch #2 commit description. - Fixed a typo (s/96Board/96Boards/) in patch #5.

[PATCH v3 00/13] Fuzzing and ASAN for sandbox
by Andrew Scull 28 Aug '23

28 Aug '23

This series introduces ASAN and a basic fuzzing infrastructure that works with sandbox. The example fuzz test towards the end of the series will find something pretty quickly. That something is fixed by the series "virtio: Harden and test vring" that needs to be applied for the final patch in this series. There is some refactoring to stop using '.' prefixed sections. ELF defines sections with names that contain anything that isn't alphanumeric or an underscore as being for system use which means clang's ASAN instrumentation happily add redzones between the contained objects. That's not what we want for things like linker lists where the linker script has carefully placed the sections contiguously. By renaming the sections, clang sees them as user sections and doesn't add instrumentation. ASAN is left disabled by default as there are still some tests that it triggers on and will need some more investigation to fix. It can be enabled with CONFIG_ASAN or passing `-a ASAN` to buildman. I abandonded the previous attempts to refactor sandbox EFI and getopt declaration as the changes resulted in problems out of the scope of this CL. I haven't tried to understand what EFI on sandbox should look like, but I have found that the linker list implementation is very brittle when up against compiler optimisation since ef123c5253 started to use static, zero-length arrays to mark the beginning and end of lists but the compiler see this as something it can get rid of. >From v1: - corrected handling of EFI symbols by sandbox linker script - per comments, some renaming and explaining - dropped RFC for dlmalloc ASAN instrumentation (work required to improve it) - added patch to reduce logging noise in fuzzer >From v2: - remove sandbox EFI and getopt refactoring, they obstruct the series - resolve a couple more ASAN errors - fix LTO, xtensa and MIPS builds - add ASAN build targets for CI Andrew Scull (13): serial: sandbox: Fix buffer underflow in puts sandbox: Rename EFI runtime sections sandbox: Rename getopt sections linker_lists: Rename sections to remove . prefix sandbox: Add support for Address Sanitizer test/py: test_stackprotector: Disable for ASAN CI: Azure: Build with ASAN enabled fuzzing_engine: Add fuzzing engine uclass test: fuzz: Add framework for fuzzing sandbox: Decouple program entry from sandbox init sandbox: Add libfuzzer integration sandbox: Implement fuzzing engine driver fuzz: virtio: Add fuzzer for vring .azure-pipelines.yml | 6 ++ Kconfig | 16 ++++ arch/Kconfig | 2 + arch/arc/cpu/u-boot.lds | 4 +- arch/arm/config.mk | 4 +- arch/arm/cpu/arm926ejs/sunxi/u-boot-spl.lds | 4 +- arch/arm/cpu/armv7/sunxi/u-boot-spl.lds | 4 +- arch/arm/cpu/armv8/u-boot-spl.lds | 4 +- arch/arm/cpu/armv8/u-boot.lds | 4 +- arch/arm/cpu/u-boot-spl.lds | 4 +- arch/arm/cpu/u-boot.lds | 6 +- arch/arm/mach-at91/arm926ejs/u-boot-spl.lds | 2 +- arch/arm/mach-at91/armv7/u-boot-spl.lds | 2 +- arch/arm/mach-omap2/u-boot-spl.lds | 4 +- arch/arm/mach-orion5x/u-boot-spl.lds | 4 +- arch/arm/mach-rockchip/u-boot-tpl-v8.lds | 4 +- arch/arm/mach-zynq/u-boot-spl.lds | 4 +- arch/arm/mach-zynq/u-boot.lds | 4 +- arch/m68k/cpu/u-boot.lds | 4 +- arch/microblaze/cpu/u-boot-spl.lds | 4 +- arch/microblaze/cpu/u-boot.lds | 4 +- arch/mips/config.mk | 2 +- arch/mips/cpu/u-boot-spl.lds | 4 +- arch/mips/cpu/u-boot.lds | 4 +- arch/nios2/cpu/u-boot.lds | 4 +- arch/powerpc/cpu/mpc83xx/u-boot.lds | 4 +- arch/powerpc/cpu/mpc85xx/u-boot-spl.lds | 4 +- arch/powerpc/cpu/mpc85xx/u-boot.lds | 4 +- arch/riscv/cpu/u-boot-spl.lds | 4 +- arch/riscv/cpu/u-boot.lds | 4 +- arch/sandbox/config.mk | 21 ++++- arch/sandbox/cpu/os.c | 76 +++++++++++++++++ arch/sandbox/cpu/start.c | 2 +- arch/sandbox/cpu/u-boot-spl.lds | 10 +-- arch/sandbox/cpu/u-boot.lds | 32 ++++---- arch/sandbox/dts/test.dts | 4 + arch/sandbox/include/asm/fuzzing_engine.h | 25 ++++++ arch/sandbox/include/asm/getopt.h | 2 +- arch/sandbox/include/asm/main.h | 18 ++++ arch/sandbox/include/asm/sections.h | 4 +- arch/sandbox/lib/sections.c | 8 +- arch/sh/cpu/u-boot.lds | 4 +- arch/x86/cpu/u-boot-64.lds | 6 +- arch/x86/cpu/u-boot-spl.lds | 6 +- arch/x86/cpu/u-boot.lds | 6 +- arch/x86/lib/elf_ia32_efi.lds | 4 +- arch/x86/lib/elf_x86_64_efi.lds | 4 +- arch/xtensa/cpu/u-boot.lds | 4 +- arch/xtensa/include/asm/ldscript.h | 13 ++- board/compulab/cm_t335/u-boot.lds | 4 +- board/cssi/MCR3000/u-boot.lds | 4 +- .../davinci/da8xxevm/u-boot-spl-da850evm.lds | 2 +- board/qualcomm/dragonboard820c/u-boot.lds | 4 +- board/samsung/common/exynos-uboot-spl.lds | 4 +- board/synopsys/iot_devkit/u-boot.lds | 4 +- board/ti/am335x/u-boot.lds | 4 +- board/vscom/baltos/u-boot.lds | 4 +- doc/api/linker_lists.rst | 22 ++--- doc/develop/commands.rst | 4 +- doc/develop/driver-model/of-plat.rst | 4 +- drivers/Kconfig | 2 + drivers/Makefile | 1 + drivers/fuzz/Kconfig | 17 ++++ drivers/fuzz/Makefile | 8 ++ drivers/fuzz/fuzzing_engine-uclass.c | 28 +++++++ drivers/fuzz/sandbox_fuzzing_engine.c | 35 ++++++++ drivers/serial/sandbox.c | 2 +- include/dm/uclass-id.h | 1 + include/fuzzing_engine.h | 51 ++++++++++++ include/linker_lists.h | 18 ++-- include/test/fuzz.h | 51 ++++++++++++ test/Makefile | 1 + test/fuzz/Makefile | 8 ++ test/fuzz/cmd_fuzz.c | 82 +++++++++++++++++++ test/fuzz/virtio.c | 72 ++++++++++++++++ test/py/tests/test_stackprotector.py | 1 + tools/mips-relocs.c | 9 +- 77 files changed, 673 insertions(+), 151 deletions(-) create mode 100644 arch/sandbox/include/asm/fuzzing_engine.h create mode 100644 arch/sandbox/include/asm/main.h create mode 100644 drivers/fuzz/Kconfig create mode 100644 drivers/fuzz/Makefile create mode 100644 drivers/fuzz/fuzzing_engine-uclass.c create mode 100644 drivers/fuzz/sandbox_fuzzing_engine.c create mode 100644 include/fuzzing_engine.h create mode 100644 include/test/fuzz.h create mode 100644 test/fuzz/Makefile create mode 100644 test/fuzz/cmd_fuzz.c create mode 100644 test/fuzz/virtio.c -- 2.36.1.124.g0e6072fb45-goog

[PATCH 0/6] introduce Arm FF-A support
by abdellatif.elkhlifi＠arm.com 17 Aug '23

17 Aug '23

From: Abdellatif El Khlifi <abdellatif.elkhlifi(a)arm.com> This patchset adds support for Arm FF-A (Arm Firmware Framework for Armv8-A v1.0). FF-A support is generic by design and can be used by any Arm platform. The features added are as follows: 1/ FF-A device driver 2/ armffa command 3/ FF-A Sandbox driver 4/ FF-A Sandbox test cases 5/ FF-A MM communication The suggested design sees FF-A as a data bus allowing data exchange with the firmware running under TrustZone HW (such as Optee). The same approach was followed in the FF-A driver in Linux kernel (https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/dri… u-boot boards using FF-A can provide a device tree node in a <board>-u-boot.dtsi file. Since the node can not be hosted in Linux device tree, we suggest using u-boot device tree. As a use case, we will send a commit enabling FF-A for the Corstone-1000 platform and providing the FF-A node in u-boot.dtsi files.

[PATCH] odroid_xu3: Fix board environment variable
by Tom Rini 14 Aug '23

14 Aug '23

When migrating CONFIG_CONS_INDEX to Kconfig, on this platform we changed what "board" evaluated to in the environment. This in turn meant that we would no longer try and find the correct fdtfile via the normal distro boot logic. Fix this by overriding board in the default environment, as done on other platforms where CONFIG_SYS_BOARD is not what we want to be in the board environment variable.

[PATCH] freescale: Remove Rajesh Bhagat MAINTAINERS
by Sean Anderson 03 Aug '23

03 Aug '23

Rajesh's email bounces. Remove his email from all boards he maintains. Fortunately, he has co-maintainers on most boards. I have taken the liberty of volunteering Pramod to maintain the LS1012AFRDM, since he also maintains the LS1012AFRWY. Let me know if the board should be orphaned instead.

How to debug u-boot data abort

Hi: I had a custom AM335X board connected my computer by usbnet. It always report data abort when 'dhcp': Next it the log: U-Boot 2022.01-rc1-00183-gfa5b4e2d19-dirty (Feb 25 2022 - 15:45:02 +0800) CPU : AM335X-GP rev 2.1 Model: WISDOM AM335X CCT DRAM: 512 MiB NAND: 256 MiB MMC: OMAP SD/MMC: 0 Loading Environment from NAND... *** Warning - bad CRC, using default environment Net: Could not get PHY for ethernet@4a100000: addr 0 eth2: ethernet@4a100000, eth3: usb_ether Hit any key to stop autoboot: 0 => setenv autoload no => dhcp using musb-hdrc, OUT ep1out IN ep1in STATUS ep2in MAC de:ad:be:ef:00:01 HOST MAC de:ad:be:ef:00:00 RNDIS ready musb-hdrc: peripheral reset irq lost! high speed config #2: 2 mA, Ethernet Gadget, using RNDIS USB RNDIS network up!
