In order to key off the brcmnand_probe() code in subsequent changes
depending upon ctrl->soc, assign that variable as early as possible,
instead of much later when we have checked that it is non-NULL.

In preparation for encapsulating more of what the loop calling
brcmnand_init_cs() does, avoid using platform_device when it is the
device behind platform_device that we are using for printing errors.

In order to initialize a given chip select object for use by the
brcmnand driver, move all of the Device Tree specific routines outside
of brcmnand_init_cs() in order to make it usable in a platform data
configuration which will be necessary for supporting BCMA chips.

The BCMA devices include the brcmnand controller but they do not wire up
any interrupt line, allow the main interrupt to be optional and update
the completion path to also check for the lack of an interrupt line.

Subject: [PATCH v3 6/9] mtd: rawnand: brcmnand: Add platform data structure for BCMA
Date: Fri, 07 Jan 2022 10:46:11 -0800
Content-Type: text/plain; charset="utf-8"
Update the BCMA's chipcommon nand flash driver to detect which
chip-select is used and pass that information via platform data to the
brcmnand driver. Make sure that the brcmnand platform data structure is
always at the beginning of the platform data of the "nflash" device
created by BCMA to allow brcmnand to safely de-reference it.

Make use of the recently refactored code in brcmnand_init_cs() and
derive the chip-select from the platform data that is supplied. Update
the various code paths to avoid relying on possibly non-existent
resources, too.

For some odd and unexplained reason the BCMA NAND controller, albeit
revision 3.4 uses a command shift of 0 instead of 24 as it should be,
quirk that.

Date: Fri, 07 Jan 2022 10:46:14 -0800
Content-Type: text/plain; charset="utf-8"
Add a BCMA shim to allow us to register the brcmnand driver using the
BCMA bus which provides indirect memory mapped access to SoC registers.
There are a number of registers that need to be byte swapped because
they are natively big endian, coming directly from the NAND chip, and
there is no bus interface unlike the iProc or STB platforms that
performs the byte swapping for us.

commands liks "ps" or "cat /proc/1/cmdline".
This fixes OpenWrt ticket #1485: https://dev.openwrt.org/ticket/1485

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.
