Move code added by Felix to the bcm-ns.dtsi which uses dual licensing.
That syncs more Northstar code to be based on the same licensing schema.
This code was added in the commit 1ff80363524c ("ARM: BCM5301X: Add

Subject: [PATCH] ARM: dts: BCM5301X: Explicitly disable unused switch CPU
ports
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
When redescribing ports I assumed that missing "label" (like "cpu")
means switch port isn't used. That was incorrect and I realized my
change made Linux always use the first (5) CPU port (there are 3 of
them).
While above should technically be possible it often isn't correct:
1. Non-default switch ports are often connected to Ethernet interfaces
not fully covered by vendor setup (they may miss MACs)
2. On some devices non-default ports require specifying fixed link
This fixes network connectivity for some devices. It was reported &
tested for Netgear R8000. It also affects Linksys EA9200 with its
downstream DTS.
Fixes: ba4aebce23b2 ("ARM: dts: BCM5301X: Describe switch ports in the main DTS")

CPU ports
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Ports 5 and 7 are disabled by default because the standard use case is
for port 8 to manage all CPU directed traffic. For experimentation
purposes however it is desirable to provide adequate properties such
that people can experiment with using different ports without having to
figure out their configuration. Some of the use cases include but are
not limited to doubling or tripling the bandwidth by leveraging the
additional ports/Ethernet MAC combinations.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Parsing every partition with "compatible" set to "brcm,trx" results in
parsing both: firmware partition and failsafe partition on devices that
implement failsafe booting. This affects e.g. Linksys EA9500 which has:
partition@200000 {
reg = <0x0200000 0x01d00000>;
compatible = "linksys,ns-firmware", "brcm,trx";
};
partition@1f00000 {
reg = <0x01f00000 0x01d00000>;
compatible = "linksys,ns-firmware", "brcm,trx";
};
Check for MTD partition name "firmware" before parsing. Recently added
ofpart_linksys_ns.c creates "firmware" and "failsafe" depending on
bootloader setup.

Subject: [PATCH] usb: xhci: add support for performing fake doorbell
Broadcom's Northstar XHCI controllers seem to need a special start
procedure to work correctly. There isn't any official documentation of
this, the problem is that controller doesn't detect any connected
devices with default setup. Moreover connecting USB device to controller
that doesn't run properly can cause SoC's watchdog issues.
A workaround that was successfully tested on multiple devices is to
perform a fake doorbell. This patch adds code for doing this and enables
it on BCM4708 family.

Subject: [PATCH] ARM: BCM5301X: Disable MMU and Dcache during decompression
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Broadcom devices have broken CFE (bootloader) that leaves hardware in an
invalid state. It causes problems with booting Linux. On Northstar
devices kernel was randomly hanging in ~25% of tries during early init.
Hangs used to happen at random places in the start_kernel. On BCM53573
kernel doesn't even seem to start booting.
To workaround this problem we need to do following very early:
1) Clear 2 following bits in the SCTLR register:
#define CR_M (1 << 0) /* MMU enable */
#define CR_C (1 << 2) /* Dcache enable */
2) Flush the whole D-cache
3) Disable L2 cache
Unfortunately this patch is not upstreamable as it does above things
unconditionally. We can't check if we are running on Broadcom platform
in any safe way and doing such hacks with ARCH_MULTI_V7 is unacceptable
as it could break other devices support.

Subject: [PATCH] net: disable GRO by default
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
In many cases GRO improves network performance however it comes at a
cost of chacksums calculations. In case of slow CPU and missing hardware
csum calculation support GRO can actually decrease network speed.
On BCM4708 *disabling* GRO results in following NAT masquarade speed
changes:
1. 364 Mb/s → 396 Mb/s (packet steering disabled)
2. 341 Mb/s → 566 Mb/s (packet steering enabled)

Subject: [PATCH] bgmac: reduce max frame size to support just MTU 1500
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
bgmac allocates new replacement buffer before handling each received
frame. Allocating & DMA-preparing 9724 B each time consumes a lot of CPU
time. Ideally bgmac should just respect currently set MTU but it isn't
the case right now. For now just revert back to the old limited frame
size.
This change bumps NAT masquarade speed by ~95%.
