-- patch the kernel kexec code to pass DTB to new kernel unconditionally
-- unpatch pernel to pass command line to kexec (breaks DTB passing)
-- decide how we specify rootfs. doing it by number is awkward
-  - may be phram
-  - may be real mtd root
-  - may be real mtd root but renumbered becuase phram exists

-Wild idea: we could probably get rid of the need for declaring a phram
-device in the first kernel, if we can use kexec to copy the squashfs into
-physical ram. As far as I can see this is a simple(sic) matter of
-specifying it as a segment, but we would have to extend kexec-tools
-to do this and it's quite a niche option if we make it do all the
-mtd setup.

-What if: we added derivations for "apply openwrt changes" as packages,
-which could then be called from the kernel derivation's extraPatchPhase?
-There could be one for generic and one for each openwrt targetop
