fs: fat: support unlink

2018-09-23T19:55:30+00:00

In this patch, unlink support is added to FAT file system.
A directory can be deleted only if it is empty.

In this implementation, only a directory entry for a short file name
will be removed. So entries for a long file name can and should be
reclaimed with fsck.

fs: fat: extend get_fs_info() for write use

2018-09-23T19:55:29+00:00

get_fs_info() was introduced in major re-work of read operation by Rob.
We want to reuse this function in write operation by extending it with
additional members in fsdata structure.

fs: fat: fix wrong casting to unsigned value of sect_to_cluster()

2018-06-13T11:49:11+00:00

After the commit 265edc03d5a1 ("fs/fat: Clean up open-coded sector
<-> cluster conversions"), it is hung up writing new file to FAT16
disk with more than 19 files in armv7. It is because result value
of sect_to_cluster() is not proper by casting from signed value to
unsigned value. Fix the wrong casting of sect_to_cluster().

SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12+00:00

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

fs: fat: Drop CONFIG_SUPPORT_VFAT

2018-01-22T21:43:31+00:00

fat.h unconditionally defines CONFIG_SUPPORT_VFAT (and has done since
2003), so as a result VFAT support is always enabled regardless of
whether a board config defines it or not. Drop this unnecessary option.

fs/fat: Clean up open-coded sector <-> cluster conversions

2017-09-15T13:03:15+00:00

Use the clust_to_sect() helper that was introduced earlier, and add an
inverse sect_to_clust(), plus update the various spots that open-coded
this conversion previously.

fs/fat: fix case for FAT shortnames

2017-09-15T13:03:14+00:00

Noticed when comparing our output to linux.  There are some lcase bits
which control whether filename and/or extension should be downcase'd.

fat/fs: move ls to generic implementation

2017-09-15T13:03:13+00:00

Add a generic implementation of 'ls' using opendir/readdir/closedir, and
replace fat's custom implementation.  Other filesystems should move to
the generic implementation after they add opendir/readdir/closedir
support.

fat/fs: remove a bunch of dead code

2017-09-15T13:03:12+00:00

Spotted by chance, when trying to remove file_fat_ls(), I noticed there
were some dead users of the API.
