[PATCH] env: correct overflow check of env_has_init size
by Patrick Delaunay 27 Jul '20

27 Jul '20

Correct the overflow check of the bit-field env_has_init with the max value of env_location= ENVL_COUNT and no more with the size of env_locations. This bit-field is indexed by this enumerate and not by the position in the env_locations (only used in env_get_location) and the 2 values are different, depending of thea ctivated CONFIG_ENV_IS_ options.

[PATCH v4 0/6] Introduce DSA Ethernet switch class and Felix driver
by Claudiu Manoil 27 Jul '20

27 Jul '20

DSA stands for Distributed Switch Architecture and it is a subsystem introduced in the Linux kernel to support switches that: - have an Ethernet link up to the CPU - use some form of tagging to identify the source/destination port for Rx/Tx - may be cascaded in tree-like structures. DSA is described in depth here: https://www.kernel.org/doc/Documentation/networking/dsa/dsa.txt >From the doc: Summarized, this is basically how DSA looks like from a network device perspective: |--------------------------- | CPU network device (eth0)| ---------------------------- | <tag added by switch | | | | | | tag added by CPU> | |--------------------------------------------| | Switch driver | |--------------------------------------------| || || || |-------| |-------| |-------| | sw0p0 | | sw0p1 | | sw0p2 | |-------| |-------| |-------| This patch set introduces a DSA class in U-Boot to support drivers of such switches. DSA drivers have to implement the following ops: - enable/disable of switch ports, - insert a tag in frames being transmitted, used by the switch to select the egress port, - parse a tag in frames being received, used for Rx traffic. DSA class code deals with presentation of switch ports as Ethernet interfaces, deals with the master Ethernet device for I/O and helps with parsing of the DT assuming the structure follows the DSA kernel binding. Support for switch cascading is not included yet. This patch set also introduces a driver for the Ethernet switch integrated into NXP LS1028A, called Felix. The switch has 4 front panel ports, I/O to/fom it is done though an ENETC Ethernet interface and meta-data is carried between the switch and the driver though an additional header pre-pended to the original frame. Network commands like tftp can be used on these front panel ports. The ports are disabled unless used so they do not cause issues on network topologies that include loops.

[PATCH v3 00/14] env: ext4: corrections and add test for env in ext4
by Patrick Delaunay 26 Jul '20

26 Jul '20

Hi, V3 of the serie [1]. In this serie, I add sandbox test with CONFIG_ENV_IS_NOWHERE activated with EXT4 location: load, save and erase. To test this feature, I add 2 new commands to change the ENV location: - env select [target] - env load This serie depends on previous env test introduced in [2] "cmd: env: add option for quiet output on env info" To be able to test invalid file (bad CRC), I also add the support of the command "env erase" for EXT4 env location.

[PATCH v2 1/1] arm: sunxi: increase SYS_MALLOC_F_LEN
by Heinrich Schuchardt 25 Jul '20

25 Jul '20

The current default of 0x400 for SYS_MALLOC_F_LEN is too small if any additional drivers marked as DM_FLAG_PRE_RELOC are loaded before relocation. CONFIG_RSA=y which is needed for UEFI secure boot or for FIT image verification loads the driver mod_exp_sw which has DM_FLAG_PRE_RELOC. CONFIG_LOG=Y is another setting requiring additional early malloc area, cf. log_init(). When running pine64-lts_defconfig with CONFIG_RSA=y and debug UART enabled we see as output in main U-Boot alloc_simple() alloc space exhausted With this patch the default values of SYS_MALLOC_F_LEN is raised to 0x2000. The default for SPL_SYS_MALLOC_F_LEN on ARCH_SUNXI is explicitely set to 0x400 to avoid an increased usage of SRAM on elder SoCs.

[PATCH] arm64: zynqmp: Fix set_fdtfile() not to break u-boots DTB
by Michal Simek 24 Jul '20

24 Jul '20

Origin function was calling strsep which replaced delimiter ',' by a null byte ('\0'). Operation was done directly on FDT which ends up with the following behavior: ZynqMP> printenv fdtfile fdtfile=xilinx/zynqmp.dtb ZynqMP> fdt addr $fdtcontroladdr ZynqMP> fdt print / compatible compatible = "xlnx", "zynqmp" As is visible fdtfile was correctly composed but a null byte caused that xlnx was separated from zynqmp. This hasn't been spotted because in all Xilinx DTs there are at least 3 compatible string and only the first one was affected by this issue. But for systems which only had one compatible string "xlnx,zynqmp" it was causing an issue when U-Boot's DT was used by Linux kernel. The patch removes strsep calling and strchr is called instead which just locate the first char after deliminator ',' (variable called "name"). And using this pointer in fdtfile composing.

Since the atheros PHY dt bindings were merged into master, we can now use them - add environment section in include/configs/kontron_sl28.h - add cover letter changes since v1: - fix watchdog device tree reference Michael Walle (2): armv8: ls1028a: move FSL_LAYERSCAPE to kconfig board: kontron: add sl28 support arch/arm/Kconfig | 10 ++ arch/arm/cpu/armv8/fsl-layerscape/Kconfig | 1 + arch/arm/dts/Makefile | 3 + .../arm/dts/fsl-ls1028a-kontron-sl28-var3.dts | 14 ++ .../arm/dts/fsl-ls1028a-kontron-sl28-var4.dts | 42 ++++++ arch/arm/dts/fsl-ls1028a-kontron-sl28.dts | 128 ++++++++++++++++++ board/kontron/sl28/Kconfig | 18 +++ board/kontron/sl28/MAINTAINERS | 6 + board/kontron/sl28/Makefile | 8 ++ board/kontron/sl28/README | 63 +++++++++ board/kontron/sl28/common.c | 10 ++ board/kontron/sl28/ddr.c | 98 ++++++++++++++ board/kontron/sl28/sl28.c | 92 +++++++++++++ board/kontron/sl28/spl.c | 9 ++ configs/kontron_sl28_defconfig | 102 ++++++++++++++ include/configs/kontron_sl28.h | 119 ++++++++++++++++ include/configs/ls1028a_common.h | 1 - 17 files changed, 723 insertions(+), 1 deletion(-) create mode 100644 arch/arm/dts/fsl-ls1028a-kontron-sl28-var3.dts create mode 100644 arch/arm/dts/fsl-ls1028a-kontron-sl28-var4.dts create mode 100644 arch/arm/dts/fsl-ls1028a-kontron-sl28.dts create mode 100644 board/kontron/sl28/Kconfig create mode 100644 board/kontron/sl28/MAINTAINERS create mode 100644 board/kontron/sl28/Makefile create mode 100644 board/kontron/sl28/README create mode 100644 board/kontron/sl28/common.c create mode 100644 board/kontron/sl28/ddr.c create mode 100644 board/kontron/sl28/sl28.c create mode 100644 board/kontron/sl28/spl.c create mode 100644 configs/kontron_sl28_defconfig create mode 100644 include/configs/kontron_sl28.h -- 2.20.1
