Hello Marek and all, I just tried latest master on colibri-imx6ull-emmc and the reset command is broken - it does nothing.
From a bisect the issue was introduced with commit 68dcbdd594d4 ("ARM:
imx: Add weak default reset_cpu()"), U-Boot releases >= v2023.07 are broken.
Any hint? I did not try to debug it myself (yet?).
Ok, the reason for the bug is simple.
Before that change we had drivers/watchdog/imx_watchdog.c:reset_cpu() implementing the reset. However that function is also weak and now the newly defined and empty weak is taking precedence.
I assume every i.MX that is not i.MX8M* or i.MX7ULP is now broken, not just i.MX6ULL nor just the colibri.
