Is it necessary to use FMAN micro code to enable Ethernet interfaces in my own standalone binary/bootloader for P2041RDB..?

If yes.. how can I integrate it?

Loading microcode is essential because it controls FMAN internal RISCs. No correct operation at all is possible

if the microcode is not loaded. Microcodes are provided as binaries, they are part of QorIQ SDK. Unpack

the package named 'fm-ucode' to get the binaries. Refer to u-boot source code, file drivers/net/fm/fm.c, function

fman_upload_firmware() on how to upload the microcode.
