From 48342ae751c797ac73ac9c894b3f312df18ffd21 Mon Sep 17 00:00:00 2001
From: Geert Uytterhoeven <geert+renesas@glider.be>
Date: Wed, 15 Sep 2021 13:46:20 +0100
Subject: [PATCH] ARM: 9124/1: uncompress: Parse "linux,usable-memory-range" DT
property
Add support for parsing the "linux,usable-memory-range" DT property.
This property is used to describe the usable memory reserved for the
crash dump kernel, and thus makes the memory reservation explicit.
If present, Linux no longer needs to mask the program counter, and rely
on the "mem=" kernel parameter to obtain the start and size of usable
memory.
For backwards compatibility, the traditional method to derive the start
of memory is still used if "linux,usable-memory-range" is absent.

From b3b76fc86f0fb4d98918f48c784138bfa950dff6 Mon Sep 17 00:00:00 2001
From: Felix Fietkau <nbd@nbd.name>
Date: Wed, 15 Jun 2022 14:53:34 +0200
Subject: [PATCH] PCI: mediatek: Allow building for ARCH_AIROHA
Allow selecting the pcie-mediatek driver if ARCH_AIROHA is set, because the
Airoha EN7523 SoC uses the same controller as MT7622.
The driver itself is not modified. The PCIe controller DT node should use
mediatek,mt7622-pcie after airoha,en7523-pcie.

Subject: [PATCH] net: bgmac: connect to PHY even if it is BGMAC_PHY_NOREGS
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Recent bgmac change was meant to just fix a race between "Generic PHY"
and "bcm53xx" drivers after -EPROBE_DEFER. It modified bgmac to use
phy_connect() only if there is a real PHY device connected.
That change broke bgmac on bcm47xx. bcma_phy_connect() now registers a
fixed PHY with the bgmac_phy_connect_direct(). That fails as another
fixed PHY (also using address 0) is already registered - by bcm47xx arch
code bcm47xx_register_bus_complete().
This change brings origial behaviour. It connects Ethernet interface
with pseudo-PHY (switch device) and adjusts Ethernet interface link to
match connected switch.
This fixes:
[ 2.548098] bgmac_bcma bcma0:1: Failed to register fixed PHY device
[ 2.554584] bgmac_bcma bcma0:1: Cannot connect to phy
Fixes: b5375509184d ("net: bgmac: improve handling PHY")

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%.

Subject: [PATCH] ssb: reject PCI writes setting CardBus bridge resources
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
If SoC has a CardBus we can set resources of device at slot 1 only. It's
impossigle to set bridge resources as it simply overwrites device 1
configuration and usually results in Data bus error-s.

Every described BCM4908 board has WP pin not connected. This caused
problems for drivers since day 0 but there was no property to describe
that properly. Projects like OpenWrt were modifying Linux driver to deal
with it.
It's not clear if that is hardware limitation or just reference design
being copied over and over but this applies to all known / supported
BCM4908 boards. Handle it by marking WP as not connected by default.

Subject: [PATCH] arm64: don't issue HVC on boot
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Broadcom's CFE loader seems to miss setting SCR_EL3.HCE which results in
generating an UNDEF and kernel panic on the first HVC.
HVC gets issued by kernels 5.12+ while booting, by kexec and KVM. Until
someone finds a workaround we have to avoid all above.

GPHY needs to be enabled to succesfully probe & setup switch port
connected to it. Otherwise hardcoding PHY OUI would be required.

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

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%.

Subject: [PATCH] mtd: don't look for OTP legacy NVMEM cells if proper node
doesn't exist
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
If node with "user-otp" / "factory-otp" compatible doesn't exist it's
important to prevent NVMEM core from looking for legacy NVMEM cells.
Otherwise it would look for them in the device node.
This fixes treating NAND controller attached chips as NVMEM cell.
Problem example:
[ 0.410107] nand: device found, Manufacturer ID: 0xc2, Chip ID: 0xdc
[ 0.416531] nand: Macronix MX30LF4G18AC
[ 0.420409] nand: 512 MiB, SLC, erase size: 128 KiB, page size: 2048, OOB size: 64
[ 0.428022] iproc_nand 18028000.nand-controller: detected 512MiB total, 128KiB blocks, 2KiB pages, 16B OOB, 8-bit, BCH-8
[ 0.438991] Scanning device for bad blocks
(...)
[ 2.848418] nvmem user-otp1: nvmem: invalid reg on /nand-controller@18028000/nand@0
[ 2.856126] iproc_nand 18028000.nand-controller: error -EINVAL: Failed to register OTP NVMEM device
This long standing issue was exposed by the support for Macronix OTP.
Reported-by: Christian Marangi <ansuelsmth@gmail.com>
Fixes: 4b361cfa8624 ("mtd: core: add OTP nvmem provider support")
Fixes: e87161321a40 ("mtd: rawnand: macronix: OTP access for MX30LFxG18AC")
