I think this change may disagree with fastboot select function on
VisionFive2 Lite, where (if I understand this correctly) it is read as
an input; see that schematic listed as the "VisionFive 2 Lit Schematic":

You may reference also the ghidra archive

for decompilation of JH-7110 BootROM loader, and there (to the best of
my understanding) it is not interacting with that register so it must be
purely the SoC reset state.
