At present devres.h is included in all files that include dm.h but few
make use of it. Also this pulls in linux/compat which adds several more
headers. Drop the automatic inclusion and require files to include devres
themselves. This provides a good indication of which files use devres.Signed-off-by: Simon Glass

Add support for operations on files larger than
CONFIG_SYS_DFU_MAX_FILE_SIZE. The buffered io mechanism is still used for

nothing is changed and they will be handled in a single filesystem call.Signed-off-by: Marek Szyprowski

When the `dfu` command is called from the U-Boot environment,
it now accepts an optional parameter that specifies a timeout (in seconds).
If a DFU connection is not made within that time the `dfu` command exits
(as it would if Ctrl+C was pressed). If the timeout is left empty or being
zero the `dfu` command behaves as it does now.This is useful for allowing U-Boot to check to see if anything wants to
upload new firmware before continuing to boot.The patch is based on the commit
https://github.com/01org/edison-u-boot/commit/5e966ccc3c65c18c9783741fa04e0c45e021780c

This patch allows the DFU backend to indicate that that it can't
provide no more data to fill the DFU buffer, by setting b_left =0
without error, even if the size of received data is lower of the
expected total size indicated by get_medium_size.For USB DFU stack point of view, it is acceptable:
the read length < requested size in DFU_UPLOAD and the
transaction is stopped.That avoid infinite loop issue in dfu_read_buffer_fill because the
size for the DFU read is limited by get_medium_size = r_left
and the DFU stack expects that read is allowed up to this size.This issue never occurs for current flash device (where chunk are
always completely read, and b_left will be never 0) but it is useful for
virtual partition when the backend only know the max size of this
alternate, the real size of the data are only known in the read
treatment.PS: for file access on mmc, EOF is never reached as
dfu_get_medium_size_mmc returns the exact size of the file.Signed-off-by: Patrick Delaunay

Add support of DFU for several interface/device

Commit 5d8fae79163e ("dfu: avoid memory leak") brings a regression which
described below. This patch is effectively reverting that commit, adding
corresponding comment to avoid such regressions in future.In case of error in dfu_config_entities(), it frees "dfu" array, which
leads to "data abort" in dfu_free_entities(), which tries to free the
same array (and even tries to access it from linked list first). The
issue occurs e.g. when partition table on device does not match
$dfu_alt_info layout:=> dfu 0 mmc 1
Couldn't find part #2 on mmc device #1
DFU entities configuration failed!
data abortTo fix this issue, do not free "dfu" array in dfu_config_entities(). It
will be freed later in dfu_free_entities().Tested on BeagleBone Black (where this regression was originally found).

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

U-Boot widely uses error() as a bit noisier variant of printf().
This macro causes name conflict with the following line in
include/linux/compiler-gcc.h:# define __compiletime_error(message) __attribute__((error(message)))
This prevents us from using __compiletime_error(), and makes it
difficult to fully sync BUILD_BUG macros with Linux. (Notice
Linux's BUILD_BUG_ON_MSG is implemented by using compiletime_assert().)Let's convert error() into now treewide-available pr_err().
