I tried applying it onto the latest main branch using:
     git am -3 < v8-Add-optimized-Makefile-support-for-SoCFPGA-handoff.patch

However, the application fails with :
    Applying: Add optimized Makefile support for SoCFPGA handoff
    error: corrupt patch at line 61
    error: could not build fake ancestor
    Patch failed at 0001 Add optimized Makefile support for SoCFPGA handoff

It looks like the patch file may have been corrupted during generation 
or transmission (possibly formatting or mbox header issues).

Could you please resend the patch in clean git format-patch (mbox) 
format so that I can apply and submit for PR.


Thanks.
