you might also be thinking of the kernel source file
init/initramfs.c, the routine populate_rootfs(), where the early
kernel processing assumes that the initrd image is defined by the two
addresses initrd_start and initrd_end.
if you look at that function, you'll see right near the top where a
call is made to unpack_to_rootfs() to extract the initrd image.
