[PATCH v5 0/7] Dissociate logical and gic/hardware CPU ID
Hi,
This is the fifth version of this patch series.
With the Versatile Express TC2, it''s possible to boot only with A7 or A15. If
the user choose to boot with only A7, the CPU ID will start at 0x100. As Xen
relies on it to set the logical ID and the GIC, it won''t be possible to use
Xen with this use case.
This patch series is divided in 3 parts:
- Patch 1: prepare Xen
