Since commit 8b41fc4454 ("kbuild: create modules.builtin without
Makefile.modbuiltin or tristate.conf"), MODULE_LICENSE declarations
are used to identify modules. As a consequence, uses of the macro
in non-modules will cause modprobe to misidentify their containing
object file as a module when it is not (false positives), and modprobe
might succeed rather than failing with a suitable error message.
So remove it in the files in this commit, none of which can be built as
modules.

SPI NOR changes:
* small fixes on core and spansion driver.
Add a mechanism to handle the case in which partitions are present as
direct child of the nand controller node and #size-cells is set to <0>.
This could happen if the nand-controller node in the DTS is supposed to
have #size-cells set to 0, but for some historical reason/bug it was set
to 1 in the past, and the firmware (e.g. U-Boot) is adding the partition
as direct children of the nand-controller defaulting to #size-cells
being to 1.
This prevents a real boot failure on colibri-imx7 that happened during v6.1
development cycles.

This fixes the following compile error on mips architecture with clang
version 16.0.0 reported by the 0-DAY CI Kernel Test Service:
ld.lld: error: undefined symbol: __udivdi3
referenced by scpart.c
mtd/parsers/scpart.o:(scpart_parse) in archive drivers/built-in.a
As a workaround this makes 'offs' a 32-bit type. This is enough, because
the mtd containing partition table practically does not exceed 1 MB. We
can revert this when the [Link] has been resolved.

Commit dd5c672d7c ("arm64: bcmbca: Merge ARCH_BCM4908 to ARCH_BCMBCA")
removes config ARCH_BCM4908 as config ARCH_BCMBCA has the same intent.
Probably due to concurrent development, commit 002181f5b1 ("mtd: parsers:
add Broadcom's U-Boot parser") introduces 'Broadcom's U-Boot partition
parser' that depends on ARCH_BCM4908, but this use was not visible during
the config refactoring from the commit above. Hence, these two changes
create a reference to a non-existing config symbol.
Adjust the MTD_BRCM_U_BOOT definition to refer to ARCH_BCMBCA instead of
ARCH_BCM4908 to remove the reference to the non-existing config symbol
ARCH_BCM4908.

There is some code in the parser that tries to read 0x8000
bytes into a block to "read in the middle" of the block. Well
that only works if the block is also 0x10000 bytes all the time,
else we get these parse errors as we reach the end of the flash:

The Sercomm partition map table contains real partition offsets, which

In the event of a skipped partition (case when the entry name is empty)
the kernel panics in the cleanup function as the name entry is NULL.
Rework the parser logic by first checking the real partition number and
then allocate the space and set the data for the valid partitions.
The logic was also fundamentally wrong as with a skipped partition, the
parts number returned was incorrect by not decreasing it for the skipped
partitions.

Some devices use fixed partitioning with some partitions requiring some
extra logic. E.g. BCM4908 may have multiple firmware partitions but
detecting currently used one requires checking bootloader parameters.
To support such cases without duplicating a lot of code (without copying
most of the ofpart.c code) support for post-parsing callback was added.
BCM4908 support in ofpart can be enabled using config option and results
in compiling & executing a specific callback. It simply reads offset of
currently used firmware partition from the DT. Bootloader specifies it
using the "brcm_blparms" property.

In the case of failure while parsing the partitions, the iterator should
be pre decremented by one before starting to free the memory allocated

Some devices (especially QCA ones) are already using hardcoded partition
names with colons in it. The OpenMesh A62 for example provides following
mtd relevant information via cmdline:
root=31:11 mtdparts=spi0.0:256k(0:SBL1),128k(0:MIBIB),384k(0:QSEE),64k(0:CDT),64k(0:DDRPARAMS),64k(0:APPSBLENV),512k(0:APPSBL),64k(0:ART),64k(custom),64k(0:KEYS),0x002b0000(kernel),0x00c80000(rootfs),15552k(inactive) rootfsname=rootfs rootwait
The change to split only on the last colon between mtd-id and partitions
will cause newpart to see following string for the first partition:
KEYS),0x002b0000(kernel),0x00c80000(rootfs),15552k(inactive)
Such a partition list cannot be parsed and thus the device fails to boot.
Avoid this behavior by making sure that the start of the first part-name
("(") will also be the last byte the mtd-id split algorithm is using for
its colon search.

With commit 91e81150d3 ("mtd: parsers: bcm63xx: simplify CFE
detection"), we generate a reference to fw_arg3 which is the fourth
firmware/command line argument on MIPS platforms. That symbol is not
exported and would cause a linking failure.
The parser is typically necessary to boot a BCM63xx-based system anyway
so having it be part of the kernel image makes sense, therefore make it
'bool' instead of 'tristate'.

Using uninitialized_var() is dangerous as it papers over real bugs[1]
(or can in the future), and suppresses unrelated compiler warnings
(e.g. "unused variable"). If the compiler thinks it is uninitialized,
either simply initialize the variable or make compiler changes.
In preparation for removing[2] the[3] macro[4], remove all remaining
needless uses with the following script:
git grep '\buninitialized_var\b' | cut -d: -f1 | sort -u | \
xargs perl -pi -e \
's/\buninitialized_var\(([^\)]+)\)/\1/g;
s:\s*/\* (GCC be quiet|to make compiler happy) \*/$::g;'
drivers/video/fbdev/riva/riva_hw.c was manually tweaked to avoid
pathological white-space.
No outstanding warnings were found building allmodconfig with GCC 9.3.0
