This is for new platform enablement for Agilex7 M-series.

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.

1c37e59bfb arm: armv8: Improve SPL data save and restore implementation
Introduce a new symbol in the beginning of .data section in
the common ARMv8 linker script and use that as a reference
for data save and restore.

Previously, the code would rely on calculating the start of
the .data section address via data size, however, we observed
that the data size does not really reflect the SPL mapped
addresses.

In our case, the binman_sym section size was not included in
the data size, which will result in a wrong address for the
.data start section, which prevents us from properly saving
and restoring SPL data.

This approach skips the calculation for the starting address
of the .data section, and instead just defines the beginning
address of the .data section and calling the symbol as needed,
in which we think as a simpler and much more robust method.

EL3 mode, this driver model provide user the high level access
to system register and abstract user from low level access.

The base address of system manager can be retrieved
using DT framework through the System Manager driver.

60d96038d7 fpga: intel_sdm_mb: add support for query SDM config error and status
Currently the FPGA reconfig status only return a single error status
which make the debugging of FPGA reconfiguration hard.

This patch is to expose the error status, major error code and
minor error code, for the FPGA reconfig to upper layer app.

dd18d65ff0 arch: arm: mach-socfpga: Mailbox buffer and SDM doorbell improvement
The current write and notify SDM to read mechanism has a flaw where
SDM is not notified enough to be able to read all the data in the buffer.

This is caused by SDM doorbell will only be sent out once the command
buffer overflow check is satisfied. If the command buffer does not reach
overflow status, no SDM doorbell will be sent out, which may cause a
timeout as the mailbox driver will be waiting for the SDM to read the
buffer to empty even though SDM is not notified to do so.

The solution is to remove the command buffer overflow check
and set the SDM doorbell to always trigger at the end of the command
buffer.

This will ensure that the SDM is able to read all of the data.
