This may not be the case - but I do recall that there was a similar
issue between u-boot.bin and u-boot.imx being loaded.
What is the format of i.MXRT?
I'm also concerned about breaking already supported in-tree boards. Why
i.MXRT needs to make this change? And why other boards don't need that
fix? (do they all have load address equal to entry point ?)
Best regards,
