serial: msm: Use single character mode
The UART DM controller supports different channel data packing modes,
either the 4-character packing mode (where 32-bit are read/written at once)
or the single-character mode (where only a single character is read/written
at a time). The 4-character mode can be more efficient, but the
single-character mode is much easier to implement.
At the moment, serial_msm uses the 4-character mode. Since the
dm_serial_ops operate on one character at the time, the code goes through
quite some hoops in order to break this down to single characters. This
code is prone to race conditions (e.g. priv->chars_cnt is read from the
registers, then a command is issued, what if another char came in
inbetween?). It also seems to cause another subtle issue with autoboot:
Unlike the previous autoboot failures that happened when UART was
disconnected, this problem occurs when UART is connected and open in a
terminal: For EFI boot, the console size is queried in efi_console.c
query_console_serial() by sending an ANSI escape code via UART. For some
reason, with the current driver we get yet another 0x00 byte (UART break
event?) when reading the reply from serial input. Because of that, reading
the console size fails in efi_console.c, the actual reply remains in the
UART buffer, and later the boot flow aborts because it detects input after
printing a prompt.
Rather than trying to fix the issue in the current complicated approach,
switch the driver to use the single-character mode. This is simple and
straightforward to implement without race conditions:
- We write one character at a time to UARTDM_TF, as long as the TX FIFO
has space available (TX_READY). To flush the console before starting
Linux, we wait for TX_EMPTY.
- We read one character at a time from UARTDM_RF and strip off the
additional error information (assuming there is something in the
RX FIFO, as indicated by RX_READY).
In this mode, querying the serial console size works and autoboot is no
longer interrupted. The overall code is also much shorter.

Revert "serial: serial_msm: Delay initialization to let pins stabilize"
There have been issues with autoboot on DB410c for years, where autoboot
gets interrupted by spurious input on the UART console. Back in 2021, I've
tried to fix this by inserting a delay before UART initialization, but it
has turned out this is not working reliably either.
It looks like the root cause has always been the lack of bias-pull-up,
which was causing the RX line to be floating when UART is disconnected.
The delay does not seem to be needed anymore when applying bias-pull-up,
so drop it again in favor of the proper fix.

The actual changes are not dramatic: the CPU cores get their caches
described properly, some A64 video clocks get fixed, some A64 boards
describe the header pins for the WiFi module, the Pinephone adds an
alternative magnetometer used on some board revisions.
On the H5 side the microSD slots get marked as having no write-protect
detection, and the NanoPi Neo Plus2 board describes its regulators better.

Merge patch series "firmware: scmi: Support SCMI LMM/CPU protocol for i.MX95"
Peng Fan (OSS) <peng.fan@oss.nxp.com> says:
i.MX95 System Manager(SM) implements Logical Machine Management(LMM) and
CPU protocol to manage Logical Machine(LM) and CPUs(eg, M7).
To manage M7 in a separate LM or in same LM as U-Boot/Linux itself. LMM
APIs and CPU APIs are needed.
When M7 is in LM 'lm-m7', and this LM is managable by 'uboot-lm', U-Boot
could use LMM_BOOT, LMM_SHUTDOWN and etc to manage 'lm-m7'.
If in same LM, use CPU_START, CPU_STOP, CPU_RESET_VECTOR_SET and etc to
manage M7.
Both LMM/CPU APIs will be used by remoteproc driver.
The documentation could be found in Linux Kernel:
drivers/firmware/arm_scmi/vendors/imx/imx95.rst

bootstd: make it possible to use tftp for netboot with standardboot
Add the option to load the bootscript with the tftp command (static IP)
instead of the dhcp command (dynamic IP). For this a new function
tftpb_run similar to dhcp_run, is needed. The selection of which command
to use can be done with the ip_dyn environment variable, which can be
set to yes or no. The ip_dyn variable was chosen as it is already in use
on the imx platforms.
Also edit the bootstd doc.

firmware: scmi: Add i.MX95 SCMI CPU Protocol
This protocol allows an agent to start, stop a CPU or set reset vector.
It is used to manage auxiliary CPUs in an LM (e.g. additional cores in an
AP cluster).

phy: ti: phy-j721e-wiz: Allow reinitialization when SERDES is pre-configured
Move the SERDES configuration check after clock and reset initialization
and change it from a hard failure to a skip of WIZ initialization. This
allows the driver to probe successfully when the SERDES has been
pre-configured by a previous boot stage (e.g., ROM or SPL).
This approach aligns with how the Linux kernel handles pre-configured
SERDES, where the driver gracefully skips reinitialization rather than
failing to probe.

firmware: scmi: Add i.MX95 SCMI LMM protocol driver
Add Logical Machine Management(LMM) protocol which is intended for boot,
shutdown, and reset of other logical machines (LM). It is usually used to
allow one LM to manager another used as an offload or accelerator engine.
Following Linux Kernel, created a separate folder for holding vendor
protocol drivers.

arm: armv8: Make save_boot_params simpler
The idiom used in save_boot_params is common for armv7.
In armv8 is much easier to do the same thing with adr/adrp.
So let's simplify the code a bit.

env: fat, ubi: Fix gd->env_valid for the first write
As resolved and explained in detail in commit
e589d5822cac ("env: spi:
Fix gd->env_valid for the first write") and archived discussion there is
a corner case where we don't do the right thing with redundant
environments. This same exact check was present in the mmc code and
resolved with commit
813a0df27a8a ("env: Invert gd->env_valid for
env_mmc_save") and in the discussion of that patch, I noted that both
fat and ubi (and at the time, sf) were doing the same thing. Take the
time now to correct fat and ubi environment.

SCMI_IMX_PROTOCOL_ID_MISC was never used, so drop it. And move
