Hello All

I am currently reworking a socfpga signer patch which is part of mkimage.

One thing I need to do is to stuff some bytes into a header ensuring the endianism is correct.

This is a trivial thing to do in C, but I have been instructed to use the existing functions put_unaligned_le32() etc.

These are part of Linux in linux/unaligned/access_ok.h. But this includes <asm/*>

It seems to me that this mixing of host space and target space is potentially problematic.

Hmm... Where exactly is there a mixing of host and target?

Is this a safe thing to do?

Thanks

Charles

Amicalement,
