Yes, that helps as it confirms that a change in u-boot alone is
enough to work around the issue in Linux as well (although it is
debateable whether the kernel should rely on the bootloader in
this case or not).  There has recently been an attempt to address
the issue in mainline u-boot, but that didn't work out as planned
and the patch got rejected:
