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.
This patch series is to be merged after efi_loader: refactor protocols management https://patchwork.ozlabs.org/project/uboot/list/?series=10409
