[Pkg-xen-devel] [PATCH 00/12] Bunch of patches for cross-compilatio + RP4

[Elliott Mitchell]

Initially out there as #965245.

I strongly prefer to build ARM64 packages on non-ARM systems.  Something
about my main build machine having twice the cores and twice the clock
speed.  As such after many builds I've managed to generate a set of
patches which appear to mostly function to get functioning cross-builds
of Xen.

These are NOT a 100% solution.  Some packaging hacks were needed.  In
particular ocaml-nox|ocaml-native-compilers is a major problem.
ocaml-nox cannot be used for cross-building.  Until ocaml-nox is fixed
the OCAML Xen bits are going to be problematic for cross-compilation.
I've worked around this to the degree possible, even though the resultant
package will have non-functioning OCAML bits replacements should drop-in.

Several of these can likely be squashed together. 1-2 are the two halves
of a bug. 3-4 are another pair, 3 is a genuine bug.  5-7 are another set.

Patch 12 is special, it has already been submitted to Xen for inclusion.
It is though *required* for functioning cross-compilation.

Patches 9-11 are already in Xen's 4.14 branch.  They are popular due to
the Raspberry PI 4's rather significant audience.  I imagine many people
using Debian on ARM highly desire them.

Elliott Mitchell (9):
  Revert "debian/rules: Do not try to move EFI binaries on armhf"
  debian/rules: Only install PV shim for supported architectures
  debian/rules: Fix binary shuffling script for cross-building
  debian/rules: Adjust boot shuffling script for POSIX
  debian/rules: Combine shared Make args
  debian/rules: Add --host to tools configure target
  debian/rules: Set CC/LD for cross-building
  debian/rules: Disable OCAML build when cross-building
  Partially revert "Cross-compilation fixes."

Julien Grall (3):
  xen/arm: Allow a platform to override the DMA width
  xen/arm: Take into account the DMA width when allocating Dom0 memory
    banks
  xen/arm: plat: Allocate as much as possible memory below 1GB for dom0
    for RPI
