What about https://lore.kernel.org/u-boot/CAFLszTjLAKaYK_jLXJ7Z571L-QMtoiqE-oxHCRs186dZ... ?
Yes, I reordered the patches in this series.
You don't need to reorder them. As Heinrich already pointed out some of these functions are used in EFI protocols. e.g duplicate_device_path() requires the memory to be allocated by EFI memory services, you can't just replace it with malloc.
The pointers returned can be freed with EFI services. I don't see any problem here. All the tests pass and all the spec rules are followed, so far as I can tell.
Where exactly does that happen in the current patch?
efi_alloc() calls efi_allocate_pool() and when we need to free the device path we are calling efi_free_pool()
Looking at it again, this wasn't very clear. The previous patch converts efi_allocate_pool() to use malloc. So this patch is not needed at all
That's right, but ultimately I'd like to drop efi_alloc() and the only other place it is used is once in lib/efi_loader/efi_bootmgr.c
