[PATCH] arm: imx8m: remove unused and obsolete board_fix_fdt() in SOC context
by Hugo Villeneuve 02 May '23

02 May '23

From: Hugo Villeneuve <hvilleneuve(a)dimonoff.com> It doesn't seem appropriate for arch/SOC to use a board-level functionality (CONFIG_OF_BOARD_FIXUP), because this prevents boards that need to do FDT fixup from using that feature. Also, this code is completely dead and useless (from comments by Rasmus Villemoes on the mailing list): - No in-tree imx8m-based board seems to set CONFIG_OF_BOARD_FIXUP - The nodes which that function wants to disable don't even exist in the U-Boot copy of imx8mp.dtsi. This code was introduced in commit 35bb60787b88. It seems to be some random import of code from downstream NXP U-Boot, with a commit message that makes no sense in upstream context.

[PATCH v5 0/2] Add MNT Reform 2 board support
by Patrick Wildt 02 May '23

02 May '23

The MNT Reform 2 is a modular DIY laptop. In its initial version it is based on the BoundaryDevices i.MX8MQ SoM. Some parts have been lifted from BoundaryDevices official U-Boot downstream project. This U-Boot patchset supports the serial console, the SD card and eMMC, Gigabit Ethernet and USB. Changes since v4: - Adjusted to Kconfig conversions. - Removed U-Boot-specific device tree changes. - Synced device tree to Linux v5.19-rc3. Changes since v3: - Adjusted to Binman changes in main branch. - Cleaned up environment variables akin to i.MX8MM. - Added vendor-prefix to device tree filename. - Provided ramdisk_addr_r. Changes since v2: - Switched to Binman. Changes since v1: - Synced DTS with files in Linux git repo. - Added support for USB host ports.

[PATCH v5 1/3] regulator: implement basic reference counter
by Eugen Hristev 01 May '23

01 May '23

Some devices share a regulator supply, when the first one will request regulator disable, the second device will have it's supply cut off before graciously shutting down. Hence there will be timeouts and other failed operations. Implement a reference counter mechanism similar with what is done in Linux, to keep track of enable and disable requests, and only disable the regulator when the last of the consumers has requested shutdown.

Pull request: u-boot-sunxi/master for 2023.07
by Andre Przywara 01 May '23

01 May '23

Hi Tom, please pull the second part of the sunxi pull request for this cycle. Another bunch of patches that replace old-school U-Boot hacks with proper DM based code, this time for the raw NAND flash driver, and the USB PHY VBUS detection code. Plus two smaller patches that were sitting in my inbox for a while. Gitlab CI passed. In lack of some supported board with NAND flash I couldn't really test this part, but apparently this was tested by the reviewer. I briefly ran the branch on some boards with USB-OTG, and this still worked.

[PATCH 00/31] Allow building sandbox with MSYS2
by Simon Glass 30 Apr '23

30 Apr '23

This expands the existing work to allow sandbox to build and run on Windows using MSYS2. It also fixes a few issues so that binman can be used. There are various limitations and some features do not work fully yet. In particular, weak functions are not well supported on Windows so these are disabled. Various minor compiler-flag and filename adjustments are also needed. This does not support SDL, so U-Boot has no display. This is potentially possible, but requires using minggw instead of the base toolchain [1] so needs to be dealt with separately.

[GIT PULL] Please pull u-boot-mpc8xx

Hi Tom, This pull request adds support for the last CPU board from CS GROUP France (previously CSSI). That CPU board called CMPCPRO has a mpc8321E CPU (Family PQII PRO hence its name) and can be plugged in place of the CMPC885 board. In order to support that new board, the following changes are included in this series: - Make the mpc8xx watchdog driver more generic for reusing it with mpc83xx - Fix various small problems on mpc83xx platform - Add a GPIO Driver for QE GPIOs - Add support for mpc832x into mpc83xx SPI driver - Refactor existing board code that will be shared with new board - Add the new board CI: https://source.denx.de/u-boot/custodians/u-boot-mpc8xx/-/pipelines/16153 Thanks Christophe The following changes since commit a25dcda452bf6a6de72764a8d990d72e5def643d: Revert "disk: Use a helper function to reduce duplication" (2023-04-03 10:43:37 -0400) are available in the Git repository at: git@source.denx.de:u-boot/custodians/u-boot-mpc8xx.git for-2023.07 for you to fetch changes up to 4d0c8db74d83e43dec4e7481b2d1e194f51d907b: board: cssi: Add CPU board CMPCPRO (2023-04-28 17:52:23 +0200) ---------------------------------------------------------------- Christophe Leroy (15): powerpc: mpc8xx: Migrate to CONFIG_SYS_CLK_FREQ watchdog: mpc8xx: Rename it mpc8xxx watchdog: mpc8xxx: Make it generic watchdog: mpc8xxx: Add support for mpc83xx powerpc: mpc832x: Fix reset word powerpc: mpc83xx: Fix soc.h powerpc: mpc83xx: Don't activate MMU when not necessary clk: mpc83xx: Fix clocks for mpc832x gpio: Add QUICC Engine GPIOs driver spi: mpc8xxx: Add support for SPI on mpc832x board: cssi: Migrate to hashed password board: cssi: Create dedicated file for common sources board: cssi: Refactor EEPROM read board: cssi: Move all mother board code into common.c board: cssi: Add CPU board CMPCPRO arch/powerpc/Kconfig | 2 +- arch/powerpc/cpu/mpc83xx/Kconfig | 5 + arch/powerpc/cpu/mpc83xx/cpu.c | 2 +- arch/powerpc/cpu/mpc83xx/hrcw/Kconfig | 3 +- arch/powerpc/cpu/mpc83xx/start.S | 4 +- arch/powerpc/cpu/mpc8xx/Kconfig | 6 +- arch/powerpc/cpu/mpc8xx/cpu_init.c | 5 +- arch/powerpc/cpu/mpc8xx/speed.c | 4 +- arch/powerpc/dts/Makefile | 1 + arch/powerpc/dts/cmpc885.dts | 12 +- arch/powerpc/dts/cmpcpro.dts | 189 +++++++++++++ arch/powerpc/dts/mcr3000.dts | 20 +- arch/powerpc/include/asm/arch-mpc83xx/gpio.h | 5 + arch/powerpc/include/asm/arch-mpc83xx/soc.h | 16 +- arch/powerpc/include/asm/mpc8xxx_spi.h | 1 + board/cssi/MAINTAINERS | 2 + board/cssi/cmpc885/Makefile | 2 +- board/cssi/cmpc885/cmpc885.c | 241 ++-------------- board/cssi/cmpcpro/Kconfig | 26 ++ board/cssi/cmpcpro/Makefile | 8 + board/cssi/cmpcpro/cmpcpro.c | 404 +++++++++++++++++++++++++++ board/cssi/cmpcpro/cmpcpro.env | 8 + board/cssi/cmpcpro/nand.c | 43 +++ board/cssi/common/common.c | 219 +++++++++++++++ board/cssi/common/common.h | 15 + board/cssi/mcr3000/mcr3000.c | 14 - configs/CMPC885_defconfig | 9 +- configs/CMPCPRO_defconfig | 209 ++++++++++++++ configs/MCR3000_defconfig | 10 +- drivers/clk/mpc83xx_clk.c | 7 + drivers/gpio/Kconfig | 18 ++ drivers/gpio/Makefile | 1 + drivers/gpio/qe_gpio.c | 170 +++++++++++ drivers/spi/mpc8xxx_spi.c | 13 + drivers/watchdog/Kconfig | 26 +- drivers/watchdog/Makefile | 2 +- drivers/watchdog/mpc8xx_wdt.c | 75 ----- drivers/watchdog/mpc8xxx_wdt.c | 112 ++++++++ include/configs/cmpc885.h | 6 + include/configs/cmpcpro.h | 99 +++++++ 40 files changed, 1668 insertions(+), 346 deletions(-) create mode 100644 arch/powerpc/dts/cmpcpro.dts create mode 100644 board/cssi/cmpcpro/Kconfig create mode 100644 board/cssi/cmpcpro/Makefile create mode 100644 board/cssi/cmpcpro/cmpcpro.c create mode 100644 board/cssi/cmpcpro/cmpcpro.env create mode 100644 board/cssi/cmpcpro/nand.c create mode 100644 board/cssi/common/common.c create mode 100644 board/cssi/common/common.h create mode 100644 configs/CMPCPRO_defconfig create mode 100644 drivers/gpio/qe_gpio.c delete mode 100644 drivers/watchdog/mpc8xx_wdt.c create mode 100644 drivers/watchdog/mpc8xxx_wdt.c create mode 100644 include/configs/cmpcpro.h
