So if you want to merge via your tree: Acked-by: Sudeep Holla 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. -- Regards, Sudeep [1] http://infocenter.arm.com/help/topic/com.arm.doc.ddi0515f/DDI0515F_juno_arm_development_platform_soc_trm.pdf
