Up to now the protocols of an EFI handle where contained in an array of fixed size. With the patch series the protocols are managed in a linked list. This both saves memory and gives more flexibility.
The LocateDevicePath boot service is implemented according to the UEFI specification.
A unit test for the LocateDevicePath boot service and the device path to text protocol are added.
Some bug fixes are provided.
v3 Remove patch efi_loader: efi_bootmgr: do not make hidden assignments (A patch to add device path printing in printf() is pending.) Resubmit efi_loader: helloworld.c: remove superfluous include v2 Enhance the helloworld example to check if the image handle is passed corectly. Adjust the related py test.
Use a helper function to initialize EFI objects.
Further minor bug fixes.
