a00a7a2570 ddr: altera: Add uibssm mailbox support for Agilex7 M-series with HBM
Add uibssm mailbox driver for Agilex7 M-series. HPS will interact with UIB
and HBM subsystem through software defined mailbox interface.
HPS can retrieve HBM memory interface calibration status, UIB
configuration, memory interfae configuration, trigger calibration and etc
with the list of supported mailbox command type and opcode.

71916a72f1 arm: socfpga: soc64: Perform warm reset after L2 reset in SPL
SPL checks for a magic word in the system manager's scratch
register to determine if an L2 reset has occurred. If detected,
SPL places all slave CPUs (CPU1–3) into WFI mode. The master
CPU (CPU0) then initiates a warm reset by writing to the RMR_EL3
system register and also enters WFI mode.

This warm reset flow is handled entirely within the HPS. The
function `socfpga_sysreset_request()` triggers the warm
reset, and upon SPL re-entry, the updated `lowlevel_init_soc64.S`
handles the necessary initialization.

binman can omit packaging an optional blob when it is missing.
This allows us to not bother with config options.
The core challenge is the interaction between tf-a and OP-TEE where
U-Boot/binman does not know whether tf-a was built with SPD=opteed or
without. This is important because tf-a might jump into the void when no
optee_os is present, leading to boot failure. Thus by marking it
optional, user is prompted to recheck (due to the warning message)
whether they really have the right combination of tf-a and optee.

Due to a bug in binman, we had to guard binman tee.bin with OPTEE config
as builds would error when tee.bin was not present in path; Even though
optee_os was marked as optional in the binman tree. Since the bug has
been resolved in
commit d4f61eae2a ("Merge patch series "Fix handling of optional blobs in binman"")
we can mark it optional again without getting build errors.

Note that after this commit a warning will be printed when optee is not
present for a binman build.

Image 'image' is missing optional external blobs but is still functional: tee-os

/binman/section/fit/images/tee/tee-os (tee.bin):
   See the documentation for your board. You may need to build Open Portable
   Trusted Execution Environment (OP-TEE) and build with TEE=/path/to/tee.bin

53158c8cf2 net: fec_mxc: Set error code on error exit
In fecmxc_probe if a timeout is detected when resetting the chip no
error code is set before taking the error exit. This could lead to a
silent failure. Instead set an error code.

d011462eea ARM: imx6: dh-imx6: Enable USB OTG ID pin pull up in SPL
Enable SoC pull up for USB OTG ID pin in SPL. There is no dedicated pull up
resistor on the SoM itself, and the pull up is mandatory for correct USB OTG
ID pin detection. U-Boot proper already configures the USB OTG ID pin pull
up via DT pinctrl node entry.

5275b5612b imx: scu_api: Remove unnecessary NULL check
In sc_seco_secvio_dgo_config there is a check for data being NULL but
this occurs after data has already been dereferenced. All callers of the
function provide a valid pointer for data so no need for the NULL check.

The minimum frequency of Fref (Fin / p) is 6MHz for the PLL AC
Electrical Characteristics. Setting p with 9 or 8 voilates the Spec.

Update the settings to match Spec.
