On some systems the host system or even the cross sysroot can
contain a version.h. This leads to the wrong file being picked
up and a PLAIN_VERSION undefined error.This workaround symlinks the version.h into the tool folder to
allow reordering of search folders.Fixes

As pointed out by Wolfgang Denk, the problem with this fix is that while
interactive users will see that we have found one part of the
environment failed and are using the other, progmatic use will not see
this and can lead to problems.Signed-off-by: Tom Rini

When reading the config file, or a script file, use getline rather than
fgets so line lengths aren't limited by the size of a compiled in buffer
(128 characters for config, 1024 for scripts).Rename 'dump' to 'line' so it's clear we're working with a line of text.

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

According to fsync specification [1] some special files (e.g., a pipe, FIFO,
or socket) don't support synchronization and return either EROFS or EINVAL.On the linux side the sys_fsync -> do_fsync() checks if the requested file
has f_op->fsync defined. If not it returns EINVAL [2].This commit prevents writing error messages for files (devices), which
do not support fsync().[1] - http://man7.org/linux/man-pages/man2/fsync.2.html

fw_env_open allocates buffers to store the environment, but these
buffers are never freed. This becomes quite nasty using the fw_ tools as
library, because each access to the environment (even just reading a
variable) generates a memory leak equal to the size of the environment.Fix this renaming fw_env_close() as fw_env_flush(), because the function
really flushes the environment from RAM to storage, and add a
fw_env_close function to free the allocated resources.Signed-off-by: Stefano Babic

Richard reported U-Boot tools issues in OpenEmbedded/Yocto project.
OE needs to be able to change the default compiler. If we pass in
HOSTCC through the make command, it overwrites all HOSTCC instances,
including ones in tools/Makefile and tools/env/Makefile, which breaks
"make cross_tools" and "make env", respectively.Add "override" directives to avoid overriding HOSTCC instances that
really need to point to the cross-compiler.Signed-off-by: Masahiro Yamada

commit 183923d3e412500bdc597d1745e2fb6f7f679ec7 enforces that the
environment must start at an erase block boundary.For block devices the sample fw_env.config does not mandate a erase block size
for block devices. A missing setting defaults to the full env size.Depending on the environment location the alignment check now errors out for
perfectly legal settings.Fix this by defaulting to the standard blocksize of 0x200 for environments
stored in a block device.
That keeps the fw_env.config files for block devices working even with that
new check.Signed-off-by: Max Krummenacher

56086921 added support for unaligned environments access.
U-boot itself does not support this:
- env_nand.c fails when using an unaligned offset. It produces an
error in nand_erase_opts{drivers/mtd/nand/nand_util.c}
- in env_sf/env_flash the unused space at the end is preserved, but
not in the beginning. block alignment is assumed
- env_sata/env_mmc aligns offset/length to the block size of the
underlying device. data is silently redirected to the beginning of
a blockThere is seems no use case for unaligned environment. If there is
some useful data at the beginning of the the block (e.g. end of u-boot)
that would be very unsafe. If the redundant environments are hosted by
the same erase block then that invalidates the idea of double buffering.
It might be that unaligned access was allowed in the past, and that
people with legacy u-boot are trapped. But at the time of 56086921
it wasn't supported and due to reasons above I guess it was never
introduced.
I prefer to remove that (unused) feature in favor of simplicitySigned-off-by: Andreas Fenkart
