I note that kconfig includes the lex/yacc output files (blah.c_shipped) so you
don't have to have lex and yacc installed to run "menuconfig". It _also_
includes the lex/yacc source which is what you patch and rebuild the _shipped
files from when they need to be changed.

Milton Miller has some patches that make a "PPC qemu target" kernel image
which doesn't include a device tree, and generates a rom image to boot qemu
with which contains a device tree and hands it off to the Linux kernel. If
qemu can merge that rom image in its BIOS collection, this approach would
meet my immediate needs.
