4 Subject: [PATCH] ARM: dts: NSP: Add DT files for Meraki MX64 series
5
6 MX64 & MX64W Hardware info:
7 - CPU: Broadcom BCM58625 Cortex A9 @ 1200Mhz
8 - RAM: 2 GB (4 x 4Gb SK Hynix H5TC4G83CFR)
9 - Storage: 1 GB (Micron MT29F8G08ABACA)
10 - Networking: BCM58625 internal switch (5x 1GbE ports)
11 - USB: 1x USB2.0
12 - Serial: Internal header
13 - WLAN(MX64W only): 2x Broadcom BCM43520KMLG on the PCI bus
14
15 This patch adds the Meraki MX64 series-specific bindings. Since some
16 devices make use of the older A0 SoC, changes need to be made to
17 accommodate this case, including removal of coherency options and
18 modification to the secondary-boot-reg.
