This gives each Secure Partition complete freedom on its address space. Previously, the memory used by the exception vectors was reserved and couldn't be used. Also, it always had to be mapped, forcing SPM to generate translation tables that included the exception vectors as well as the Partition memory regions. With this change, partitions can reduce their address space size easily. Change-Id: I67fb5e9bdf2870b73347f23bff702fab0a8f8711 Signed-off-by: Antonio Nino Diaz <antonio.ninodiaz@arm.com>
