[Xen-devel] [PATCH v9 0/4] xen/arm: Add support for Huawei hip04-d01 platform

[Frediano Ziglio <frediano.ziglio@xxxxxxxxxx>]

This set of patches add Xen support for hip04-d01 platform (see
https://wiki.linaro.org/Boards/D01 for details).

Changes from v8:
- added a maintainer (Julien Grall);
- reduce difference from gic-hip04.c and gic-v2.c (Julien Grall);
- specify base gic-v2.c for gic-hip04.c (Julien Grall);
- other minor fixes (Julien Grall);
- rewrite patch to check for interrupt controller nodes using
  device list classes.

Changes from v7:
- updated patches;
- moved interrupt controller check in a separate patch (Ian Campbell);
- changed conditional include of gic-hip04.c in Makefile (Ian Campbell);
- added MAINTAINERS update (Ian Campbell).

Changes from v6:
- collapsed some patch (Julien Grall);
- remove useless check for irq values;
- test interrupt controller not using DT compatibility;
- remove non standard drivers flag (Ian Campbell).

Changes from V5.99.1:
- removed RFC again;
- use different constants for hip04 instead of redefine standard ones;
- comment compatible string change;
- add an option to ARM to enable non standard drivers;
- rename gicv2 to hip04gic to make clear this is not a standard gic.

Changes from v5:
- do not change gic-v2.c code but use a copy.

To be considered RFC, to see if better to use copy or other techniques.

Changes from v4:
- rebased to new version;
- removed patch for computing GIC addresses as it apply to all platforms;
- removed patches to platform (cpu and system operations) as now they can
  use a bootwrapper which provide them.

Changes from v3:
- change the way regs property is computed for GICv2 (Julien Grall);
- revert order of compaible names for GIC (Julien Grall).

Changes from v2:
- rewrote DTS fix patch (Ian Campbell);
- use is_hip04 macro instead of doing explicit test (Julien Grall);
- do not use quirks to distinguish this platform (Ian Cambell);
- move some GIC constants to C files instead of header (Julien Grall);
- minor changes (Julien Grall).

Changes from v1:
- style (Julien Grall);
- make gicv2_send_SGI faster (Julien Grall);
- cleanup correctly if hip04_smp_init fails (Julien Grall);
- remove quirks using compatibility (Ian Campbell);
- other minor suggestions by Julien Grall.

Frediano Ziglio (4):
  xen/arm: Duplicate gic-v2.c file to support hip04 platform version
  xen/arm: Detect GIC nodes based on class
  xen/arm: Make gic-v2 code handle hip04-d01 platform
  xen/arm: Force dom0 to use normal GICv2 driver on Hip04 platform
