This series adds support for file renaming to EFI_FILE_PROTOCOL.SetInfo(). One of the use cases for renaming in EFI is to facilitate boot loader boot counting.
No existing filesystems in U-Boot currently include file renaming, resulting in support for renaming at the filesystem level and a concrete implementation for the FAT filesystem.
