We could also do a better job of identifying when different things
(initrd, kernel, dtb) overlap in memory.

detect error when kernel and initrd images exceed ram size
Status in QEMU:
I was unable to figure out why my VM wasn't booting when I added a
"-initrd" image. I would launch qemu and get no output, and no error
message, it would just spin.
Turns out my initrd image was around 270 MB but I wasn't giving an
explicit ram size to qemu. I was told the default memory size was
around 120 MB so this was definitely a problem. I think that the qemu
"pseudo-bootloader" should detect when the kernel image and initrd
image sizes exceed the size of ram and print a nice error to the user,
Error: the total size of the given boot images (342M) exceeds the size
allocated for memory (120M)
