Subject: [PATCH v3 1/2] ARM64: zynqmp: Use 64bit size cell format
Use 64bit size cell format instead of 32bit for memory
description. Change 64bit sizes also for all others IPs.
Signed-off-by: Michal Simek <michal.simek@...inx.com>
---
Changes in v3:
- Get back to origin solution used in v1.
(https://lkml.org/lkml/2016/2/11/220)
PCIe has a need to describe 8GB and 256GB and this node is placed on
amba bus and IP itself is placed there. Getting pcie node out of amba
bus is wrong solution because it is not there in HW.
Space will be used for configuration and prefetchanble memory
Changes in v2:
- Use ranges for PS amba busses instead of changing them to
64 size cell
