Comment:

 Initial implementation by svn 2800, with test build at
 dev.laptop.org:~wmb/a4c11ma.rom .  By default, that build exports the old
 ATAGs thing in r2.  If you type "use-fdt" before booting, it will instead
 export the flattened device tree via r2.

 This is just a first step.  The device tree needs a lot of work, to

 a) Ensure that necessary device nodes are present in the right form.  One
 example is the twsi node, which should be split into multiple twsi at address
 nodes.

 b) Add interrupts properties to all relevant nodes.

 The Linux kernel needs work too...
