I'm _really_ against disabling relocation of the device tree or ramdisk
when we have enough information to do said checks as it inevitably leads
to people finding a kernel + ramdisk + dtb combination where the kernel
BSS ate something.  What exactly is the layout you're seeing where
things fail, and why can we not use (or, update) bootm_size to describe
the overall region?  Thanks!
