[PATCH v2 0/6] This series adds support for file renaming to EFI_FILE_PROTOCOL.SetInfo().

[Gabriel Dalimonte]

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.

Changes in v2:
 - update create_link() docstring
 - remove ATTR_ARCH being implicitly set in create_link()
 - cleanup log message and verbosity in fs_rename()
 - update fs_close() docstring with reference to fs_rename()
 - clarify fs_rename() behaviour in docstring
 - change fatrename to mv (updating semantics to match mv)
 - add mv command docs
 - add FAT_RENAME Kconfig symbol
 - update rename tests for mv command semantics
 - update rename test docs on whether mv should succeed or fail
 - remove all (fat) prefixes from commands used in rename tests
 - clarify docs in check_path_prefix()
 - stack allocate fat_itr in check_path_prefix()
 - log on observed filesystem corruption in check_path_prefix()
 - change 'break's to 'goto' in check_path_prefix()
 - normalize added logging to use log_debug()
 - correct error code returned when destination directory is not empty
 - remove setting ATTR_ARCH on parent dirs during renames
 - skip updating timestamps if no RTC present
 - make fat_itr stack allocated in update_parent_dir_props
 - update parent dir props in create_link and delete_dentry_link
 - simplify freeing of new_file_name and new_path

Gabriel Dalimonte (6):
  fs: fat: factor out dentry link create/delete
  fs: add rename infrastructure
  fs: fat: add rename
  fs: fat: update parent dirs metadata on dentry create/delete
  efi_loader: move path out of file_handle
  efi_loader: support file rename in SetInfo()
