error compiling ffmpeg on a T4

HI!
It seems to me than on my kernel 5.7.2 I have all the requirements meet to enable the VPU acceleration.

building on armhf root

Hi, I'm trying to build ffmpeg with your script on a debian bullseye on pbp with an aarch64 kernel and an armhf root but I think that there are some aarch64 libraries hardcoded somehere.
I get the error:
/libavutil/aarch64/bswap.h:31:5: error: invalid 'asm': invalid operand for code 'w'
Is there a way to fix this or maybe I've to compile with an arm64 buildchain?
thanks in advance
Matteo

kernel 5.10 mainline?

I tried this scripts and it works well,
I built kernel 5.8.5.
Is there a way to build a newer kernel (such as kernel 5.10) with this script?
