The message
"** %s shorter than offset + len **\n"
may be interesting when debugging but it does not indicate an
error.So we should not write it if we are not in debug mode.
Fixes: 7a3e70cfd88c fs/fs.c: read up to EOF when len would read past EOF

Needed to support efi file protocol. The fallback.efi loader wants
to be able to read the contents of the /EFI directory to find an OS
to boot.Modelled after POSIX opendir()/readdir()/closedir(). Unlike the other
fs APIs, this is stateful (ie. state is held in the FS_DIR "directory
stream"), to avoid re-traversing of the directory structure at each
step. The directory stream must be released with closedir() when it
is no longer needed.Signed-off-by: Rob Clark

FAT and ext4 expect that the passed in block device descriptor not be
NULL. This causes problems on sandbox, where get_device_and_partition()
succeeds for the "host" device, yet passes back a NULL device descriptor.

commands operate as expected on sandbox.Signed-off-by: Stephen Warren

This could be used in scripts such as:
if test -e mmc 0:1 /boot/boot.scr; then
load mmc 0:1 ${scriptaddr} /boot/boot.scr
source ${scriptaddr}
firather than:
if load mmc 0:1 ${scriptaddr} /boot/boot.scr; then
source ${scriptaddr}
fiThis prevents errors being printed by attempts to load non-existent
files, which can be important when checking for a large set of files,
such as /boot/boot.scr.uimg, /boot/boot.scr, /boot/extlinux.conf,
/boot.scr.uimg, /boot.scr, /extlinux.conf.Signed-off-by: Stephen Warren

Fix a few issues with the generic "save" shell command, and fs_write()
function.1) fstypes[].write wasn't filled in for some file-systems, and isn't
checked when used, which could cause crashes/... if executing save
on e.g. fat/ext filesystems.2) fs_write() requires the length argument to be non-zero, since it needs
to know exactly how many bytes to write. Adjust the comments and code
according to this.3) fs_write() wasn't prototyped in like other generic functions;
other code should be able to call this directly rather than invoking
the "save" shell command.Signed-off-by: Stephen Warren

As documented, almost all U-Boot commands expect numbers to be entered
in hexadecimal input format. (Exception: for historical reasons, the
"sleep" command takes its argument in decimal input format.)This rule was broken for the "load" command; for details please see
especially commits 045fa1e "fs: add filesystem switch libary,
implement ls and fsload commands" and 3f83c87 "fs: fix number base
behaviour change in fatload/ext*load". In the result, the load
command would always require an explicit "0x" prefix for regular
(i. e. base 16 formatted) input.Change this to use the standard notation of base 16 input format.
While strictly speaking this is a change of the user interface, we
hope that it will not cause trouble. Stephen Warren comments (see
[1]):I suppose you can change the behaviour if you want; anyone
writing "0x..." for their values presumably won't be
affected, and if people really do assume all values in U-Boot
are in hex, presumably nobody currently relies upon using
non-prefixed values with the generic load command, since it
doesn't work like that right now.[1] http://article.gmane.org/gmane.comp.boot-loaders.u-boot/171172

This allows write of files from the host filesystem in sandbox. There is
currently no concept of overwriting the file and removing its existing
contents - all writing is done on top of what is there. This means that
writing 10 bytes to the start of a 1KB file will only update those 10
bytes, not truncate the file to 10 byte slong.If the file does not exist it is created.

When the generic filesystem load command "fsload" was written, I felt
that "load" was too generic of a name for it, since many other similar
commands already existed. However, it turns out that there is already
an "fsload" command, so that name cannot be used. Rename the new
"fsload" to plain "load" to avoid the conflict. At least anyone who's
used a Basic interpreter should feel familiar with the name!Signed-off-by: Stephen Warren

Commit 045fa1e "fs: add filesystem switch libary, implement ls and
fsload commands" unified the implementation of fatload and ext*load
with the new command fsload. However, this altered the interpretation
of command-line numbers from always being base-16, to requiring a "0x"
prefix for base-16 numbers. Enhance do_fsload() to allow commands to
specify which base to use.Use base 0, thus requiring a "0x" prefix for the new fsload command.
This feels much cleaner than assuming base 16.Use base 16 for the pre-existing fatload and ext*load to prevent a
change in behaviour.Use base 16 exclusively for the loadaddr environment variable, since
that variable is interpreted in multiple places, so we don't want the
behaviour to change.Update command help text to make it clear where numbers are assumed to
be hex, and where an explicit "0x" prefix is required.Signed-off-by: Stephen Warren
