[PATCH v2 0/5] Add Broadcom Northstar Plus Support

[PATCH v2 0/5] Add Broadcom Northstar Plus Support

[Jon Mason]

Changes in version 2 incorporate Olof's comments regarding:
* the removal of all "Reviewed-by" lines not occurring on external
  mailing lists
* reordering of s-o-b lines
* modification of the device tree file to use labels when enabling
* increated description of the modification to the MAINTAINERS entry

Also, modifying the "to" and "cc" recepients so that everyone is
receving all of the patches.

+Broadcom Northstar Plus device tree bindings
+--------------------------------------------
+
+Broadcom Northstar Plus family of SoCs are used for switching control
+and management applications as well as residential router/gateway
+applications. The SoC features dual core Cortex A9 ARM CPUs, integrating
+several peripheral interfaces including multiple Gigabit Ethernet PHYs,
+DDR3 memory, PCIE Gen-2, USB 2.0 and USB 3.0, serial and NAND flash,
+SATA and several other IO controllers.
+
+Boards with Northstar Plus SoCs shall have the following properties:

Jon, you can send a replacement patch and I would drop this one. Thanks!

[PATCH v2 3/5] ARM: NSP: Add basic support for Broadcom Northstar Plus SoC

[Jon Mason]

Broadcom Northstar Plus family of SoCs are used for switching
control and management applications as well as residential
router/gateway applications. The SoC features dual core Cortex
A9 ARM CPUs, integrating several peripheral interfaces including
multiple Gigabit Ethernet PHYs, DDR3 memory, PCIE Gen-2, USB 2.0
and USB 3.0, serial and NAND flash, SATA and several other IO
controllers.

Applied to soc/next at github.com/stblinux, thanks!

This is a little late for 4.3, so this will be queued for 4.4, thanks!

[PATCH v2 5/5] MAINTAINERS: add entry for the Broadcom Northstar Plus SoCs

[Jon Mason]

Modify the iProc MAINTAINER to cover the Nortstar Plus SoCs, and add me
to the list of people responsible for it.  Since iProc is a family of
SoCs that includes more than just Cygnus (i.e., Northstar (BCM5301X),
Northstar Plus, Northstar 2, and a number of other platforms), remove it
from the title to avoid any future confusion.
