The only case when it is not aligned is when IOMMU_PAGE_SIZE > PAGE_SIZE

Meraki was founded in 2006. The start-up quickly rose to prominence
by being based in part on the MIT Roofnet Project.
In December 2012, Cisco Systems, Inc. bought Meraki.
The "Meraki" branding is still around to this day.

This patch adds an DTSI-File that can be used by various device-tree
files for APM82181-based devices.
Some of the nodes (like UART, PCIE, SATA) are used by the uboot and
need to stick with the naming-conventions of the old times'.
I've added comments whenever this was the case. But
Hello,
I've been holding on to these devices dts' for a while now.
But ever since the recent purge of the PPC405, I'm feeling
the urge to move forward.
The devices in question have been running with OpenWrt since
around 2016/2017. Back then it was linux v4.4 and required
many out-of-tree patches

This patch adds the device-tree definitions for
Western Digital MyBook Live NAS devices.
CPU: AMCC PowerPC APM82181 (PVR=12c41c83) at 800 MHz
(PLB=200, OPB=100, EBC=100 MHz)
32 kB I-Cache 32 kB D-Cache, 256 kB L2-Cache, 32 kB OnChip Memory
DRAM: 256 MB (2x NT5TU64M16GG-AC)
FLASH: 512
This patch adds the device-tree definitions for Meraki MR24
Accesspoint devices.
Board: MR24 - Meraki MR24 Cloud Managed Access Point
CPU: APM82181 SoC 800 MHz (PLB=200 OPB=100 EBC=100)
Flash size: 32MiB
RAM Size: 128MiB
Wireless: Atheros AR9380 5.0GHz + Atheros AR9380 2.4GHz
EPHY: 1x Gigabit
This patch tries to integrate the existing bluestone.dts into the
apm82181.dtsi framework.
The original bluestone.dts produces a peculiar warning message.
