This has NOTHING to do with ramdisk sizes.

U-Boot does not uncompress ramdisk images, this is done by the  Linux
kernel.  U-Boot  just  (loads  and) passes the address of the ramdisk
image to the Linux kernel without touching the data at all.

No such change is needed (unless you end up with a Linux kernel  that
does not fit in 4 MB any more).

Best regards,
