Finally got JTAG to work just enough to dive into this. Turned out to be
another case of the FDT clashing with the BSS area. Your patch caused
BSS to grow by > 4 MiB so that it now collides with the (old) default
FDT location on this board. There's nothing wrong with your patch, just
the usual black magic of placing initramfs and FDT in RAM on ARM.
