On Linux, add support for arbitrary baudrates. (Since there is no

tools: kwboot: Support higher baudrates when booting via UART
Add support for uploading the boot image (the data part only) at higher
baudrate than the standard one.
The kwboot utility already has -B option, but choosing other baudrate
than the standard one (115200 Bd) can only work for debug mode, not for
booting the device. The BootROM for kwboot supported platforms (Orion,
Kirkwood, Dove, Discovery, AXP, A37x, A38x, A39x) cannot change the
baudrate when uploading boot image via the Xmodem protocol, nor can it
be configured via strapping pins.
So instead we add this support by injecting baudrate changing code into
the kwbimage v1 header as a new optional binary extension. This code is
executed by BootROM after it receives the whole header. The code sends
the magic string "$baudratechange\0" just before changing the baudrate
to let kwboot know that it should also change it. This is because the
injected code is run as the last binary extension, and we do not want
to loose possible output from other possible binary extensions that
came before it (in most cases this is U-Boot SPL).
We also inject the code before the payload (the data part of the image),
to change the baudrate back to the standard value, in case the payload
does not reset UART.
This change improves boot time via UART significantly (depending on the
chosen baudrate), which is very useful when debugging.

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
b86f43de0be0 ("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.

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.

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
0e146993bb3 (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.

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.

Before
e2e95e5e254 ("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

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:

1512016235-15909-1-git-send-email-Bhaskar.Upadhaya@nxp.com/
it became apparent that nobody really knows what "SGMII 2500" is.
Certainly, Freescale/NXP hardware engineers name this protocol
"SGMII 2500" in the reference manuals, but the PCS devices do not
support any "SGMII" specific features when operating at the speed of
2500 Mbps, no in-band autoneg and no speed change via symbol replication
. So that leaves a fixed speed of 2500 Mbps using a coding of 8b/10b
with a SERDES lane frequency of 3.125 GHz. In fact, "SGMII 2500 without
in-band autoneg and at a fixed speed" is indistinguishable from
"2500base-x without in-band autoneg", which is precisely what these NXP
devices support.
So it just appears that "SGMII 2500" is an unclear name with no clear
definition that stuck.
As such, in the Linux kernel, the drivers which use this SERDES protocol
use the 2500base-x phy-mode.
This patch converts U-Boot to use 2500base-x too, or at least, as much
as it can.
Note that I would have really liked to delete PHY_INTERFACE_MODE_SGMII_2500
completely, but the mvpp2 driver seems to even distinguish between SGMII
2500 and 2500base-X. Namely, it enables in-band autoneg for one but not
the other, and forces flow control for one but not the other. This goes
back to the idea that maybe 2500base-X is a fiber protocol and SGMII-2500
is an MII protocol (connects a MAC to a PHY such as Aquantia), but the
two are practically indistinguishable through everything except use case.
NXP devices can support both use cases through an identical configuration,
for example RX flow control can be unconditionally enabled in order to
support rate adaptation performed by an Aquantia PHY. At least I can
find no indication in online documents published by Cisco which would
point towards "SGMII-2500" being an actual standard with an actual
definition, so I cannot say "yes, NXP devices support it".

net: dsa: felix: call phy_config at .port_probe() time
It is an unfortunate reality that some PHY settings done by U-Boot
persist even after the PHY is reset and taken over by Linux, and even
more unfortunate that Linux has come to depend on things being set in a
certain way.
For example, on the NXP LS1028A-RDB, the felix switch ports are
connected to a VSC8514 QSGMII PHY. Between the switch port PCS and the
PHY, the U-Boot drivers enable in-band auto-negotiation which makes the
copper-side negotiated speed and duplex be transmitted from the PHY to
the MAC automatically.
The PHY driver portion that does this is in vsc8514_config():
/* Enable Serdes Auto-negotiation */
phy_write(phydev, MDIO_DEVAD_NONE, PHY_EXT_PAGE_ACCESS,
PHY_EXT_PAGE_ACCESS_EXTENDED3);
val = phy_read(phydev, MDIO_DEVAD_NONE, MIIM_VSC8514_MAC_SERDES_CON);
val = val | MIIM_VSC8574_MAC_SERDES_ANEG;
phy_write(phydev, MDIO_DEVAD_NONE, MIIM_VSC8514_MAC_SERDES_CON, val);
The point is that in-band autoneg should be turned on in both the PHY
and the MAC, or off in both the PHY and the MAC, otherwise the QSGMII
link will be broken.
And because phy_config() is currently called at .port_enable() time, the
result is that ports on which traffic has been sent in U-Boot will have
in-band autoneg enabled, and the rest won't.
It can be argued that the Linux kernel should not assume one way or
another and just reinitialize everything according to what it expects,
and that is completely fair. In fact, I've already started an attempt to
remove this dependency, although admittedly I am making slow progress at
it:
https://patchwork.kernel.org/project/netdevbpf/cover/
20210212172341.3489046-1-olteanv@gmail.com/
Nonetheless, the sad reality is that NXP also has, apart from kernel
drivers, some user space networking (DPDK), and for some reason, the
expectation there is that somebody else initializes the PHYs. The kernel
can't do it because the device ownership doesn't belong to the kernel,
so what remains is for the bootloader to do it (especially since other
drivers generally call phy_config() at probe time). This is a really
weak guarantee that might break at any time, but apparently that is
enough for some.
Since initializing the ports and PHYs at probe time does not break
anything, we can just do that.
