fca315a382 arch: powerpc: mpc85xx: ensure mdiodev->name is NULL terminated after MDIO_NAME_LEN 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 MDIO_NAME_LEN - 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.

7c2d5d1642 net: freescale: replace usage of phy-mode = "sgmii-2500" with "2500base-x"
After the discussion here:
https://lore.kernel.org/netdev/20210603143453.if7hgifupx5k433b@pali/

which resulted in this patch:
https://patchwork.kernel.org/project/netdevbpf/patch/20210704134325.24842-1-pali@kernel.org/

and many other discussions before it, notably:
https://patchwork.kernel.org/project/linux-arm-kernel/patch/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".

77b11f7604 net: replace the "xfi" phy-mode with "10gbase-r"
As part of the effort of making U-Boot work with the same device tree as
Linux, there is an issue with the "xfi" phy-mode. To be precise, in
Linux there was a discussion (for those who have time to read:
https://lore.kernel.org/netdev/1576768881-24971-2-git-send-email-madalin.bucur@oss.nxp.com/)

which led to a patch:
https://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next.git/commit/?id=c114574ebfdf42f826776f717c8056a00fa94881

TL;DR: "xfi" was standardized in Linux as "10gbase-r".

This patch changes the relevant occurrences in U-Boot to use "10gbase-r"
instead of "xfi" wherever applicable.

ee91d46557 arm: mach-k3: common: Make sure firmware sections are loaded prior to armv8 startup
With Device Manager firmware in an elf file form, we cannot load the FIT
image to the exact same address as any of the executable sections of the
elf file itself is located.

However, the device tree descriptions for the ARMV8 bootloader/OS
includes DDR regions only the final sections in DDR where the Device
Manager firmware is actually executing out of.

As the R5 uC is usually operating at a slower rate than an ARMv8 MPU,
by starting the Armv8 ahead of parsing the elf and copying the correct
sections to the required memories creates a race condition where the
ARMv8 could overwrite the elf image loaded from the FIT image prior to
the R5 completing parsing and putting the correct sections of elf in
the required memory locations. OR create rather obscure debug conditions
where data in the section is being modified by ARMV8 OS while the elf
copy is in progress.

To prevent all these conditions, lets make sure that the elf parse and
copy operations are completed ahead of ARMv8 being released to execute.

We will pay a penalty of elf copy time, but that is a valid tradeoff in
comparison to debug of alternate scenarios.

6887f8e00b arm: mach-k3: am6_init: Prioritize MSMC traffic over DDR in NAVSS Northbridge
NB0 is bridge to SRAM and NB1 is bridge to DDR.

To ensure that SRAM transfers are not stalled due to delays during DDR
refreshes, SRAM traffic should be higher priority (threadmap=2) than
DDR traffic (threadmap=0).

This fixup is critical to provide deterministic access latency to
MSMC from ICSSG, it applies to all AM65 silicon revisions and is due
to incorrect reset values (has no erratum id) and statically setting
things up should be done independent of usecases and board.

This specific style of Northbridge configuration is specific only to
AM65x devices, follow-on K3 devices have different data prioritization
schemes (ASEL and the like) and hence the fixup applies purely to
AM65x.

Without this fix, ICSSG TX lock-ups due to delays in MSMC transfers in
case of SR1 devices, on SR2 devices, lockups were not observed so far
but high retry rates of ICSSG Ethernet (icssg-eth) and, thus, lower
throughput.

turn serve as inputs to other HSDIV output clocks. These clocks use
the actual value to compute the divider clock rate, and need to be

From a Kconfig interface perspective, it makes sense to present two

implementation from sha512.c. The latter doesn't make any sense.

It's reasonable to say in Kconfig that SHA384 depends on SHA512, and

Thus, automatically select SHA512 when SHA384 is enabled.

52ff1626cf xilinx: common: Enabling generic function for DT reselection
U-Boot support board detection at run time and based on it change DT.
This feature is implemented for SOM Kria platforms which contain two
eeproms which contain information about SOM module and CC (Carrier card).
Full U-Boot starts with minimal DT file defined by
CONFIG_DEFAULT_DEVICE_TREE which is available in multi DTB fit image.
It is using default setup of board_name variable initializaed to
DEVICE_TREE which corresponds to CONFIG_DEFAULT_DEVICE_TREE option.

When DTB_RESELECT is enabled board_detection() is called. Keep it your mind
that this code is called before relocation. board_detection() is calling
xilinx_read_eeprom() which fills board_info (xilinx_board_description)
structure which are parsed in board_name_decode().
Based on DT configuration and amount of nvmemX aliases name of the board is
composed by concatenating CONFIG_SYS_BOARD "-" <board_name> "-rev"
<board_revision> "-" <cc_name> "-rev" <cc_revision>.

If CC is not present or more are available it keeps going.

When board name is composed and returned from board_name_decode() it is
assigned to board_name variable which is used by
board_fit_config_name_match() which is called via fdtdec_setup() when it
goes over config options in multi dtb FIT image.

From practical point of view multi DTB image is key point here which has to
contain configs for detected combinations. Unfortunately as of now they
have to be full DTBs and DTBOs are not supported.

That's why configuration like:
config_X {
	description = "zynqmp-board-cc";
	fdt = "board", "cc";
};

needs to be squashed together with:
fdtoverlay -o zynqmp-board-cc -i arch/arm/dts/zynqmp-board.dtb \
arch/arm/dts/zynqmp-cc.dtbo

and only one dtb is in fit:
config_X {
	description = "zynqmp-board-cc";
	fdt = "board-cc";
};

For creating multi DTBs fit image use mkimage -E, e.g.:
mkimage -E -f all.its all.dtb

When DTB_RESELECT is enabled xilinx_read_eeprom() is called before
relocation and it uses calloc for getting a buffer. Because this is dynamic
memory it is not relocated that's why xilinx_read_eeprom() is called again
as the part of board_init(). This second read with calloc buffer placed in
proper position board_late_init_xilinx() can setup u-boot variables as
before.

e69213611e xilinx: zynqmp: Generate different u-boot.itb for MULTI_DTB_FIT
When MULTI_DTB_FIT is enabled fit-dtb.blob fit image is created which
contain all DTBs listed by CONFIG_OF_LIST. And with DTB_RELESELECT there is
a need to handle it as one file with DTBs in it not as separate DTBs in
u-boot.its/itb.
That's why extend mkimage_fit_atf.sh to generate u-boot.itb correctly.
