[U-Boot] [PATCH v2 0/8] fs/fat: cleanups + readdir implementation

[Rob Clark <robdclark@gmail.com>]

Introduce directory traversal iterators, and implement fs_readdir()
which is needed by EFI_LOADER.

The part re-working fat.c to use the directory iterators itself is
nearly a 2:1 negative diffstat, and a pretty big cleanup.  I fixed
one or two other small issues along the way.  It hasn't really been
tested with a wide variaty of different fat filesystems (if someone
has a collection of disk images to test with somewhere, let me know),
but it seems at least not worse than what it is replacing.

Changes since v1:
 * fix+comment downcase()
 * fix partition-is-whole-disk case
 * fix missing fs_closedir() in generic ls implementation

Rob Clark (8):
  fs/fat: split out helper to init fsdata
  fs/fat: introduce new director iterators
  fat/fs: convert to directory iterators
  fs: add fs_readdir()
  fs/fat: implement opendir/readdir/closedir
  fat/fs: remove a bunch of dead code
  fat/fs: move ls to generic implementation
  fs/fat: fix case for FAT shortnames
