[Xen-devel] [PATCH 00/10 V5] arm: support for initial modules (e.g. dom0) and DTB supplied in RAM

[Ian Campbell <Ian.Campbell@xxxxxxxxxx>]

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 in this posting is to push the device-tree PoC bits to
the end of the series after the more generic mechanisms, as discussed in
<1355913325.14620.303.camel@xxxxxxxxxxxxxxxxxxxxxx>. The earlier patches
can now potentially be committed while the later ones (specifically
patches 8 + 9) are still under discussion.

I've included Stefano's "flush dcache after memcpy'ing the kernel image"
patch here too since it depends on the refactoring in this series.

Ian.
