Generally yes. I'd like to point out though, that PX30 currently sets it unconditionally as well. I thought there may be valid reason to do so in cases where we don't actually use the mainline SPL but an rkbin miniloader blob or something. There was a mention of that in rockchip.rst. In that case, moving it into XPL_BUILD might break, depending on whatever the mini- loader does. > > We should possibly also clear SOC_CON1 to handle reset in similar way as > TF-A / PSCI reset.

So this would make the BOOT_MODE_REG survive every global reset regardless of cause. Is that the intention? I could see a wrinkle with a watchdog specifically: What if the cause of the WDT reboot is related to BOOT_MODE_REG? E.g. we built a U-Boot that somehow locks up during USB boot, then trips the watchdog. The philosophical question now: Should the watchdog go back to maskrom again or resume the standard boot behavior? I guess my expectation would be the latter but not totally sure. Best, Andreas
