This depends. When the bootwrapper version is used then yes, the kernel should
get changed. This is because the bootwrapper detects the SDRAM size from the
DDR2 controller and passes it to Linux.
Without bootwrapper no changes are needed, since U-Boot already passes the
corrected memory size to Linux (totalsize-4k currently).
