[Concept] ARM64 EFI_STUB on SM6115

I'm currently trying to bring a SM6115 device on Linux but... without much success... I have replaced my ABL with qcomm/abl2eps which allows me to boot an efi application. I've tried to use ARM64 EFI STUB for that but the resulting u-boot-efi-payload.efi doesn't look like an PE32+ binary.... file u-boot-payload.efi u-boot-payload.efi: data Could you help me Thanks
