Refind 0.14.2 can boot if compiled with gnu-efi 3.0.18, but if I use a jpeg banner it is all garbled. If compiled with gnu-efi 3.0.17, the jpeg looks good.

I tried to use libeg/nanojpeg.c from 0.14.0 with the same result (still garbled).

Nice.

Why not just use refit_call3_wrapper gBS->SetMem and drop the specific GNUEFI macros in lib.h? Also extend to cover refit_call3_wrapper gBS->CopyMem as well.

Other toolkits will also happily work with these. I note though, that you tried to follow the same way things were previously done.
