Turns out Microship (formerly Micrel) meanwhile integrated proper support for the DLL setup on their KSZ9131. Unfortunately, this conflicts with our previous board code doing that. Fix this by getting rid of our board code and just relying on the generic implementation relying on rgmii-id being used as phy-mode.

Fixes: commit c6df0e2ffdc4 ("net: phy: micrel: add support for DLL setup on ksz9131") Fixes: commit af2d3c91d877 ("ARM: dts: imx8mm-verdin: Set PHY mode to RGMII-ID") Signed-off-by: Marcel Ziswiler marcel.ziswiler@toradex.com Reviewed-by: Fabio Estevam festevam@gmail.com

Prepare for DEK blob encapsulation support through "dek_blob" command. On ARMv8, u-boot runs in non-secure, thus cannot encapsulate a DEK blob for encrypted boot. The DEK blob is encapsulated by OP-TEE through a trusted application call. U-boot sends and receives the DEK and the DEK blob binaries through OP-TEE dynamic shared memory.

To enable the DEK blob encapsulation, add to the defconfig: CONFIG_SECURE_BOOT=y CONFIG_FAT_WRITE=y CONFIG_CMD_DEKBLOB=y

Taken from NXP's commit 56d2050f4028 ("imx8m: Add DEK blob encapsulation for imx8m").

Changes in v3: - Case fold hex string. - Revert binman part of imx8mm-verdin-u-boot.dtsi to a plain copy from imx8mm-evk and postpone further improvements to after migrating to a common binman config as agreed with Frieder and Simon.

Changes in v2: - Explicitly pass filename to binman when generating binaries as suggested by Heiko. - Use proper intermediate binary u-boot-spl-ddr.bin for imximage as pointed out by Heiko.

Variable "kernel_image" is used in boot.scr script only, that sets its own default value to the constant string @@KERNEL_IMAGETYPE@@ in case "kernel_image" is not set. The default name of the kernel image shipped with BSP 5.x is "Image.gz". Setting kernel_image="Image" as a pre-defined u-boot variable breaks booting systems with modern versions of boot.scr, whereas renaming it fixes booting with modern scripts and does not break working of earlier versions of boot.scr.

While at it also update the copyright period, rather than hard-coding fdtfile default fdt_board to dev for the Verdin iMX8M Mini and fix its closing #endif comment.

Enable and set preboot var with fdtfile evaluation. It will be checked and run immediately before starting the CONFIG_BOOTDELAY countdown and/or running the auto-boot command resp. entering interactive mode.

This provides possibility to use different boot cmds in interactive mode without manual setting fdtfile value, as it it's already evaluated before entering interactive mode.

Finally, found the root cause of the issue already once mentioned back here [2] which caused the following error message during boot:

imx_wdt watchdog@30280000: pinctrl_select_state_full: uclass_get_device_by_phandle_id: err=-19

Turns out while the watchdog node itself was already u-boot,dm-spl its pinctrl node was not which caused it to be unavailable at that early stage. Note that any and all other boards I checked also seem to be missing this. However, I can't judge whether or not they might indeed need a similar fix or not.
