[Xen-devel] [PATCH 00/09 V4] arm: support for initial modules (e.g. dom0) and DTB supplied in RAM

[Ian Campbell <Ian.Campbell@xxxxxxxxxx>]

(I appear to have labelled V3 as V2 when I sent it out, so this V4)

The following series implements support for initial images and DTB in
RAM, as opposed to in flash (dom0 kernel) or compiled into the
hypervisor (DTB). It arranges to not clobber these with either the h/v
text on relocation or with the heaps and frees them as appropriate.

Most of this is independent of the specific bootloader protocol which is
used to tell Xen where these modules actually are, but I have included a
simple PoC bootloader protocol based around device tree which is similar
to the protocol used by Linux to find its initrd
(where /chosen/linux,initrd-{start,end} indicate the physical address).

The PoC protocol is documented in docs/misc/arm/device-tree/booting.txt
which is added by this series.

The major change this time is to use /chosen/modules/module@<N> rather
than /chosen/module@<N> plus using the compatible node to differentiate
which node is which (so <N> is now arbitrary).

As ever the bootloader half is at:
