This commit introduces a new API,
request_firmware_into_buf_via_script(),
to the fs_loader framework.
This function allows firmware to be loaded into memory
using a user-defined U-Boot script,
providing greater flexibility for firmware loading scenarios that
cannot be handled
by static file paths or device/partition selection alone.
Please run some 'fmt -w 72' on the paragraph above.
Got it. Will modify for the next version.

I've validated this API on the Banana Pi R3 Mini. Here are my test
commands and logs:
1. `env set en8811h_load_firmware 'env set fw_addr 0x46000000 && env
set fw_size 0x24000 && load mmc 0:3 0x46000000 /boot/EthMD32.dm.bin
&& load mmc 0:3 0x46004000 /boot/EthMD32.DSP.bin
The 'load' command sets $filesize variable AFTER the load completed.
The $filesize variable contains the actual size of the loaded data.
You will likely need to expand the script a bit:
env set fw_addr 0x46000000 && env set fw_size 0x24000 && \
mw.b ${fw_addr} 0 ${fw_size} && # Make sure the memory backing the
# firmware is initialized to some valid
# content.
load mmc 0:3 0x46000000 /boot/EthMD32.dm.bin && \
if test ${filesize} -lt 0x4000 ; then # Validate that the size of loaded
# data is correct
load mmc 0:3 0x46004000 /boot/EthMD32.DSP.bin
# Validate loaded data size here again
else
env set fw_size 0 # Indicate failure
exit 1
fi
OK. I will expand the script you mention.

Looks pretty good otherwise I think , thanks !
Thank you for your great advice.
