[Xen-devel] [PATCH v4 04/10] xen/arm: Switch to SYS_STATE_boot just after end_boot_allocator()

[Julien Grall <julien.grall@xxxxxxx>]

We should consider the early boot period to end when we stop using the
boot allocator. This is inline with x86 and will be helpful to know
whether we should allocate memory from the boot allocator or xenheap.
