Change on it own looks good. So if you want to merge via your tree:
Acked-by: Sudeep Holla <sudeep.holla@arm.com>
Let me know if you decide not to take it via your tree and you want me
to send it to arm-soc.
On the side note I just noticed the Juno TRM[1] has 64k for each of
these MSI frames(page 3-24 section 3.3.5 Application memory map summary)
I am not sure if TRM is wrong. This patch is just copying the 4k size
from frame 0 which got added with initial Juno DTS.
