Simultaneous support of CONFIG_MX6UL and CONFIG_MX6ULL
by Matthias Schiffer 09 Nov '21

09 Nov '21

Hi everyone, for the submission of support for our TQMa6UL/TQMa6ULL SoM family I've been wondering if it would be desirable to allow U-Boot configs that support both i.MX6UL and i.MX6ULL. This would allow us to reduce the number of required defconfig variants for our SoMs significantly. I had a look at the differences between these configurations, and most of the code already treats both SoCs the same (lots of "#if defined(CONFIG_MX6UL) || defined(CONFIG_MX6ULL)"). The differences are sufficiently small that it seems easy to change them to use runtime detection for the SoC variant (and maybe not even leave CONFIG_MX6UL and CONFIG_MX6ULL as separate config symbols): - MX6UL selects HAS_CAAM. Runtime detection should already work (will double-check) - Fuse support: Easy to switch to runtime detection - mx6ul_pins.h vs. mx6ull_pins.h: Mostly identical. Only definitions for GPIO5 differ (and none of the differing definitions are used at all) I can propose patches for these changes if you think that it is a good idea. Kind regards, Matthias

[PATCH 0/2] Initial Traverse Ten64 board support
by Mathew McBride 09 Nov '21

09 Nov '21

This patchset adds initial support for the Traverse Ten64 family, which is a networking focused Mini-ITX board using NXP's LS1088A. This patchset is the bare minimum necessary to get a system running on U-Boot and booting via distroboot/EFI. There are still a few more drivers to come, such as the I2C setup for the USB5744 hub and EMC2301 fan controller. Additionally, this patchset does not contain any of the defaults (e.g bootmenu settings) we have in our official firmware releases. This set contains two additions: - The driver for the board microcontroller The microcontroller holds the board MAC address and controls some board functions (like power to the 10G retimer). This has been placed in boards/traverse/common/ as future Traverse products may use it as well. - The board file itself Mathew McBride (2): board: traverse: add Ten64 board controller driver board: traverse: add initial Ten64 support arch/arm/Kconfig | 16 + arch/arm/dts/Makefile | 2 + arch/arm/dts/fsl-ls1088a-ten64.dts | 377 ++++++++++++++++++++ board/traverse/common/Kconfig | 6 + board/traverse/common/Makefile | 1 + board/traverse/common/ten64-controller.h | 28 ++ board/traverse/common/ten64_controller.c | 238 +++++++++++++ board/traverse/ten64/Kconfig | 17 + board/traverse/ten64/MAINTAINERS | 8 + board/traverse/ten64/Makefile | 6 + board/traverse/ten64/eth_ten64.c | 49 +++ board/traverse/ten64/ten64.c | 433 +++++++++++++++++++++++ configs/ten64_tfa_defconfig | 119 +++++++ include/configs/ten64.h | 55 +++ 14 files changed, 1355 insertions(+) create mode 100644 arch/arm/dts/fsl-ls1088a-ten64.dts create mode 100644 board/traverse/common/Kconfig create mode 100644 board/traverse/common/Makefile create mode 100644 board/traverse/common/ten64-controller.h create mode 100644 board/traverse/common/ten64_controller.c create mode 100644 board/traverse/ten64/Kconfig create mode 100644 board/traverse/ten64/MAINTAINERS create mode 100644 board/traverse/ten64/Makefile create mode 100644 board/traverse/ten64/eth_ten64.c create mode 100644 board/traverse/ten64/ten64.c create mode 100644 configs/ten64_tfa_defconfig create mode 100644 include/configs/ten64.h -- 2.30.1

[PATCH] configs: Layerscape: Remove the 'fdt_addr' env
by Zhiqiang Hou 09 Nov '21

09 Nov '21

From: Hou Zhiqiang <Zhiqiang.Hou(a)nxp.com> On Layerscape platforms, the DTB is loaded from boot filesystem, per the fdt_addr description in doc/README.distro, it must be removed. And on many platforms, like ls1046a, ls1088a, ls2088a and lx216xa, the 'fdt_addr' pointed address is not accessible. And with the current EFI boot process, since the EFI_LOADER and CMD_BOOTEFI_BOOTMGR are enabled by default, if the EFI boot components are not deployed in the boot filesystem, it will try to get DTB at address 'fdt_addr' and then result in "SError" or "Synchronous Abort": Error log on ls1046ardb: => run distro_bootcmd switch to partitions #0, OK mmc0 is current device Scanning mmc 0:1... libfdt fdt_check_header(): FDT_ERR_BADMAGIC Scanning disk esdhc(a)1560000.blk...

From: Chao Zeng <chao.zeng(a)siemens.com> When operating the write-protection flash,spi_flash_std_write() and spi_flash_std_erase() would return wrong result.The flash is protected, but write or erase the flash would show "OK".
