00a1deed1c tools: kwboot: Fix kwboot_xm_sendblock() function when kwboot_tty_recv() fails
When kwboot_tty_recv() fails or times out, it does not set the `c`
variable to NAK. The variable is then compared, while it holds either
an undefined value or a value from previous iteration. Set `c` to NAK so
that the other side will try to resend current block, and remove the
now unnecessary break.

In other failure cases return immediately.

e453bb42ce tools: kwboot: Refactor and fix writing buffer
There are 3 instances in kwboot.c where we need to write() a given
buffer whole (iteratively writing until all data are written), and 2 of
those instances are wrong, for they do not increment the buffer pointer.

Refactor the code into a new function kwboot_write() where it is fixed.

c67fecd212 ARM: zynq: Enable capsule update for qspi and mmc
Generate dfu_alt_info setup at runtime for capsule update.
Enabling this feature will help with upgrading boards without remembering
what is where.

The similar change was done for ZynqMP by commit b86f43de0b ("xilinx:
zynqmp: Add support for runtime dfu_alt_info setup").
Code needs to be enabled by CONFIG_SET_DFU_ALT_INFO.

And also enable capsule on disk for RAW firmware images with efidebug
command.

Two indexes are supported for SPL flow. Images can be generated like:
./tools/mkeficapsule --raw spl/boot.bin --index 1 capsule1.bin
./tools/mkeficapsule --raw u-boot.img --index 2 capsule2.bin

Then place them to SD card and load them:
load mmc 0 10000000 capsule1.bin && efidebug capsule update -v 10000000
load mmc 0 10000000 capsule2.bin && efidebug capsule update -v 10000000

FSBL flow will also work where only index 1 capsule is used. There
should be enough space for using boot.bin with bitstream too.

Zynq also support multiple boot locations in SPI or MMC but it is not wired
by this patch.

65513f3c18 arm: dts: armada8040: Fix CP0 eMMC/SDIO support
During the migration to a single DTSI for the CP110-s specific pinctrl
compatibles were moved to the SoC DTSI as CP0 and CP1 have some specifics.
Namely, CP0 eMMC/SDIO support depends on the mvebu-pinctrl driver setting
the BIT(0) in eMMC PHY IO Control 0 Register to 0 in order for the connect
the eMMC/SDIO PHY to the controller and not use it as a MPP pin multiplexor.

So, the mvebu-pinctrl driver check specifically for the
"marvell,armada-8k-cpm-pinctrl" compatible to clear the that bit.

Issue is that compatibles in the 8040 DTSI were set to "marvell,8k-cpm-pinctrl"
for CP0 and "marvell,8k-cps-pinctrl" for the CP1.
This is obviously incorrect as the pinctrl driver does not know about these.

So fix the regression by applying correct compatibles to the DTSI.
Regression found and tested on the Puzzle M801 board.

24ea366add imx: imx7d-sdb: fix ethernet, sync .dts with linux
Commit 0d52bab46 (mx7dsabre: Enable DM_ETH) changed these flags from 0
(aka GPIO_ACTIVE_HIGH) to GPIO_ACTIVE_LOW. It claimed to "Also sync
device tree with v5.5-rc1", but in the linux tree, these gpios have
always been GPIO_ACTIVE_HIGH ever since this node was introduced
around v4.13 (linux commit 184f39b5).

I'm guessing that the reason for the GPIO_ACTIVE_LOW was to work
around the behaviour of the soft-spi driver back then, which
effectively defaulted to spi-mode 3 and not 0. That was arguably a bug
in the soft-spi driver, which then got fixed in 0e146993bb (spi: add
support for all spi modes with soft spi), but that commit then broke
ethernet on this board.

Fix it by setting the gpios as active high, which as a bonus actually
brings us in sync with the .dts in the linux source tree.

Without this, one gets

    Net:   Could not get PHY for FEC0: addr 0
    No ethernet found.

With this, ethernet (at least ping and tftp) works as expected from
the U-Boot shell.

b8919eaa68 mtd: nand: raw: convert nand_dt_init() to ofnode_xx() interface
nand_dt_init() is still using fdtdec_xx() interface.
If OF_LIVE flag is enabled, dt property can't be get anymore.
Updating all fdtdec_xx() interface to ofnode_xx() to solve this issue.

For doing this, node parameter type must be ofnode.

First idea was to convert "node" parameter to ofnode type inside
nand_dt_init() using offset_to_ofnode(node). But offset_to_ofnode()
is not bijective, in case OF_LIVE flag is enabled, it performs an assert().

So, this leads to update nand_chip struct flash_node field from int to
ofnode and to update all nand_dt_init() callers.

b81ce79df0 mtd: spi: Set CONFIG_SF_DEFAULT_MODE default to 0
Before e2e95e5e25 ("spi: Update speed/mode on change") most systems
silently defaulted to SF bus mode 0. Now the mode is always updated,
which causes breakage. It seems most SF which are used as boot media
operate in bus mode 0, so switch that as the default.

This should fix booting at least on Altera SoCFPGA, ST STM32, Xilinx
ZynqMP, NXP iMX and Rockchip SoCs, which recently ran into trouble
with mode 3. Marvell Kirkwood and Xilinx microblaze need to be checked
as those might need mode 3.

a4f2d83414 mtd: spi: nor: force mtd name to "nor%d"
Force the mtd name of spi-nor to "nor" + the driver sequence number:
"nor0", "nor1"... beginning after the existing nor devices.

This patch is coherent with existing "nand" and "spi-nand"
mtd device names.

When CFI MTD NOR device are supported, the spi-nor index is chosen after
the last CFI device defined by CONFIG_SYS_MAX_FLASH_BANKS.

When CONFIG_SYS_MAX_FLASH_BANKS_DETECT is activated, this config
is replaced by to cfi_flash_num_flash_banks in the include file
mtd/cfi_flash.h.

This generic name "nor%d" can be use to identify the mtd spi-nor device
without knowing the real device name or the DT path of the device,
used with API get_mtd_device_nm() and is used in mtdparts command.

This patch also avoids issue when the same NOR device is present 2 times,
for example on STM32MP15F-EV1:

The same mtd name "mx66l51235l" identify the 2 instances
mx66l51235l@0 and mx66l51235l@1.

This patch fixes a ST32CubeProgrammer / stm32prog command issue
with nor0 target on STM32MP157C-EV1 board introduced by
commit b7f060565e ("mtd: spi-nor: allow registering multiple MTDs when
DM is enabled").

4df9f5e39f scripts: ensure the cocci script for miiphy_register does not leak the MDIO bus
When mdio_register fails, mdio_free should be called on the mdiodev that
was previously allocated with mdio_alloc.

4fdc7e3530 net: dsa: ensure port names are NULL-terminated after DSA_PORT_NAME_LENGTH truncation
strncpy() simply bails out when copying a source string whose size
exceeds the destination string size, potentially leaving the destination
string unterminated.

One possible way to address is to pass DSA_PORT_NAME_LENGTH - 1 and a
previously zero-initialized destination string, but this is more
difficult to maintain.

The chosen alternative is to use strlcpy(), which properly limits the
copy len in the (srclen >= size) case to "size - 1", and which is also
more efficient than the strncpy() byte-by-byte implementation by using
memcpy. The destination string returned by strlcpy() is always NULL
terminated.

bf35c3121a net: mdio-uclass: rewrite dm_mdio_post_probe using strlcpy
dm_mdio_post_probe used to be vulnerable after truncation, but has been
patched by commit 398e7512d8 ("net: Fix Covarity Defect 244093").
Nonetheless, we can use strlcpy like the rest of the code base now,
which yields the same result.
