Subject: [PATCH] mtd: parsers: trx: parse "firmware" MTD partitions only
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] bcm53xx: partition fixups for Meraki MX64/MX65
We need to enlarge the u-boot partition to add extra features like UBI
booting. The shmoo and newly created env partitions can easily be moved
to the nvram partition. This fixup allows u-boot to be enlarged to up to
1MiB.

Subject: [PATCH] bcm53xx: dts: meraki-mx6x: add OpenWrt-specific LED aliases
Assign green power LED for "boot", "running", orange for "upgrade" and
red for "failsafe" functions - the same as done for MR33 and MR74.

Subject: [PATCH] ARM: dts: BCM5301X: add root pcie bridges
They are always required and instead of duplicating a definition in each
dts file, place it in dtsi with labels and work based on that.
Also changed each bridge@ to pcie@ to get extra dtc static analysis.
Fixed bridge numbers as a result.

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)
