This function is a variant of fs_get_type_name() and returns a filesystem
type with which the current device is associated.
We don't want to export fs_type variable directly because we have to take
care of it consistently within fs.c.Signed-off-by: AKASHI Takahiro

fs_ls(), fs_mkdir() and fs_unlink() sets fs_type to FS_TYPE_ANY
explicitly, but it is redundant as they call fs_close().
So just remove those lines.Signed-off-by: AKASHI Takahiro
Reviewed-by: Heinrich Schuchardt -
fs_close() closes the connection to a file system which opened with
either fs_set_blk_dev() or fs_set_dev_with_part(). Many file system
functions implicitly call fs_close(), e.g. fs_closedir(), fs_exist(),
fs_ln(), fs_ls(), fs_mkdir(), fs_read(), fs_size(), fs_write()
and fs_unlink().
So just export it.Signed-off-by: AKASHI Takahiro

fatload command can be used to load the EFI payload since EFI system
partition is always a FAT partition. Call into EFI code from do_load()
to set the device path from which the last binary was loaded. An EFI
application like grub2 can’t find its configuration file without the
device path set.Since device path is now set in do_load() there is no need to set it
in do_load_wrapper() for the load command.Signed-off-by: Mian Yousaf Kaukab

Unlike other generic FS accessors, fs_get_info() does not call fs_close()
at the end of it's operation. Thus, using fs_get_info() in do_fs_type()
without calling fs_close() causes potential memory leak by creating new
filesystem structures on each call of do_fs_type().The test case to trigger this problem is as follows. It is required to
have ext4 filesystem on the first partition of the SDMMC device, since
ext4 requires stateful mount and causes memory allocation.
=> while true ; do mmc rescan ; fstype mmc 1 ; done
Eventually, the mounting of ext4 will fail due to malloc failures
and the filesystem will not be correctly detected.This patch fixes the problem by adding the missing fs_close().

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.Signed-off-by: Tom Rini

fs APIs, this is stateful (ie. state is held in the FS_DIR "directory

is no longer needed.Signed-off-by: Rob Clark
