mtdparts quit when invalid mtd devices found. Add thes patches to skip
the invalid devices, so NAND partitions can be alway found to burn boot
images.For instance,
On i.MX6DL Sabreauto, nand config u-boot didn't enable the weim nor, so
parsing 8000000.nor leads to error:Device nor0 not found!
With the patches, we can skip this invalid device and still get nand
boot partition table:Device nor0 not found!
current device is invalid, skip it and check the next onedevice nand0 , # parts = 5

All U-Boot users must define the mtdparts environment variable with:
setenv mtdparts mtdparts=...While this may ease the partition declaration job to be passed to
Linux, this is a pure software limitation and forcing this prefix is a
complete non-sense. Let the user to declare manually the mtdparts
variable without the prefix.Signed-off-by: Miquel Raynal

In the case that there was no name defined for a partition the
code assumes that name_len is 22 and therefore allocates exactly
that space for a dummy name. But the function sprintf() first
resolves "0x%08llx@0x%08llx" to a string that is longer than 22
bytes. This leads to a buffer overflow. The replacement function
snprintf() limits the copied bytes to name_len and therefore
avoids the buffer overflow.Signed-off-by: Kay Potthoff

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

This header was renamed to rawnand.h in Linux.
The following is the corresponding commit in Linux.
commit d4092d76a4a4e57b65910899948a83cc8646c5a5
Author: Boris Brezillon
Date: Fri Aug 4 17:29:10 2017 +0200mtd: nand: Rename nand.h into rawnand.h
We are planning to share more code between different NAND based
devices (SPI NAND, OneNAND and raw NANDs), but before doing that
we need to move the existing include/linux/mtd/nand.h file into
include/linux/mtd/rawnand.h so we can later create a nand.h header
containing all common structure and function prototypes.Signed-off-by: Masahiro Yamada

When reworking this code to fix other issues found by Coverity, I forgot
to ensure tmp_ep was always cleared before use.Reported-by: Coverity (CID: 166612)

As part of fixing the previously reported issues, it was missed that in
the case of mtdparts_init() we need to make sure that tmp_ep is long
enough to contain PARTITION_MAXLEN and a NULL termination. Then, to be
sure the buffer is NULL terminated, zero the entire buffer rather than
just ensuring the first character is NULL.Cc: Lothar Waßmann

Now that sandbox is building cmd/mtdparts.c Coverity has looked at the
code and found a number of issues. In index_partitions() it is possible
that part will be NULL, so re-work the checks and debug statements to
take this into account. We have a number of string buffers that we
print to in the exact size of, and use string functions on, so we need
to ensure they are large enough to be NULL terminated. In
device_parse() it is not possible for num_partitions to be 0 (we would
have hit a different error first) so remove logically dead code.
Finally, in parse_mtdparts() if we have an error we need to free the
memory allocated to dev.Cc: Lothar Waßmann

CMD_MTDPARTS is something the user might or might not want to select, and
might depends on (or be selected by) other options too.This is even truer for the MTDIDS_DEFAULT and MTDPARTS_DEFAULT options that
might change from one board to another, or from one user to the other,
depending on what it expects and what storage devices are available.In order to ease that configuration, add those options to Kconfig.

Some CPUs contains boot ROM code capable reading first few blocks
(where SPL resides) of NAND flash and executing it. It is wise to
create separate partition here for SPL. As block size depends on
NAND chip used, we could either use worst case (biggest) partition
size or base its size on actual block size. This patch adds support
for the latter option.Signed-off-by: Ladislav Michl

Boards which are defining default mtdparts often need them early
in boot process (to load environment from UBI volume, for example).
This is currently solved by adding mtdparts and mtdids variable
definitions also to default environment. With this change, default
partitions are used by default unless explicitely deleted or
redefined.Signed-off-by: Ladislav Michl

NULL is assigned to p, which is later fed to strncpy.
Also function parameter mtdparts is completely ignored, so use it
