[PATCH 1/1] efi_loader: stop watchdogs in ExitBootServices()
by Heinrich Schuchardt 10 Nov '21

10 Nov '21

The UEFI specification requires for ExitBootServices() that "the boot services watchdog timer is disabled". We already disable the software watchdog. We should additionally disable the hardware watchdogs.

[PATCH 00/11] fsl_esdhc_imx: port several patches from fsl_esdhc
by Sean Anderson 10 Nov '21

10 Nov '21

This series ports some of the patches from fsl_esdhc to fsl_esdhc_imx. Because these drivers share a common lineage, many of these patches apply with minor changes. For each one, I have noted the originating commit in the style of linux stable backports. In fa33d20749 ("mmc: split fsl_esdhc driver for i.MX"), Yangbo says > For the two series processors, the eSDHCs are becoming more and more different However, these drivers are still extremely similar; the differences between them are not major. However, NXP has not done a good job of porting patches which apply to both drivers. This causes the fsl_esdhc_imx driver to rot, as the fsl_esdhc gets more general fixes. For this reason, I think that the fsl_esdhc_imx driver should be removed unless NXP can commit to creating series like this which port patches which apply to both drivers.

[PATCH 1/1] watchdog: don't autostart watchdog on Sunxi boards
by Heinrich Schuchardt 09 Nov '21

09 Nov '21

The Sunxi boards only support a 16 second watchdog timeout. This is too short to boot Linux. The UEFI specification requires 300 seconds as default timeout.

U-boot is broken with -O0?
by Oleh Kravchenko 09 Nov '21

09 Nov '21

Hello guys! I think the CI verification job for u-boot patches should be updated to include CFLAGS like -O0 Because I'm not able to build u-boot for Raspberry Pi (or to another board) with -O0 Here the commands how to quickly reprodice the problem: export ARCH=arm64 export CROSS_COMPILE=aarch64-linux-gnueabi- export KCFLAGS=-O0 make rpi_4_defconfig make -j$(nproc) I've attached part of the build log to this email. P.S.: Sorry if I've added you to CC by mistake.

[RFC PATCH 00/23] sunxi: Add and use a pinctrl driver
by Samuel Holland 09 Nov '21

09 Nov '21

This series resolves some longstanding TODOs by implementing a pinctrl driver for sunxi platforms and converting DM drivers to use it. I am sending this as RFC because I have only tested this on a limited amount of hardware, and there are quite a few magic numbers involved, so it is likely I missed something. Also, I'm not sure the how best to split up the patches by subsystem, or if that is necessary. This series depends on the sunxi-gpio series I just sent.

[PATCH v3 0/6] Improved sysreset/watchdog uclass integration
by Samuel Holland 09 Nov '21

09 Nov '21

This series hooks up the watchdog uclass to automatically register watchdog devices for use with sysreset, doing a bit of minor cleanup along the way. The goal is for this to replace the sunxi board-level non-DM reset_cpu() function. I was surprised to find that the wdt_reboot driver requires its own undocumented device tree node, which references the watchdog device by phandle. This is problematic for us, because sunxi-u-boot.dtsi file covers 20 different SoCs with varying watchdog node phandle names. So it would have required adding a -u-boot.dtsi file for each board. Hooking things up automatically makes sense to me; this is what Linux does. However, I put the code behind a new option to avoid surprises for other platforms. Changes in v3: - Move condition to wdt-uclass.c to fix build errors. - Include watchdog name in error message. Changes in v2: - Extend the "if SYSRESET" block to the end of the file. - Also make gpio_reboot_probe function static. - Rebase on top of 492ee6b8d0e7 (now handle all watchdogs). - Added patches 5-6 as an example of how the new option will be used.
