e334c01df2 mtd: parsers: bcm47xxpart: make read-only array possible_nvram_sizes static const
Don't populate the read-only array possible_nvram_sizes on the stack at
run time, instead make it static const.

ea265e483e mtd: Use of_property_read_bool()
Use of_property_read_bool() to read boolean properties rather than
of_get_property(). This is part of a larger effort to remove callers
of of_get_property() and similar functions. of_get_property() leaks
the DT property data pointer which is a problem for dynamically
allocated nodes which may be freed.

2538af030d mtd: cmdlinepart: Replace dbg() macro with pr_debug()
This macro was left over from the dawn of Git history.
For some reason it was defined in such a way that
you needed double brackets around it. Replace it with
the now-standard `pr_debug()`.

3e79e1b4ad mtd: bcm63xxpart: remove MODULE_LICENSE in non-modules
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.

84549c816d mtd: parsers: ofpart: add workaround for #size-cells 0
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.

105c14b84d mtd: parsers: scpart: fix __udivdi3 undefined on mips
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.

085679b15b mtd: parsers: refer to ARCH_BCMBCA instead of ARCH_BCM4908
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.

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:

9b78ef0c79 mtd: parsers: add support for Sercomm partitions
This adds an MTD partition parser for the Sercomm partition table that
is used in some Beeline, Netgear and Sercomm routers.

The Sercomm partition map table contains real partition offsets, which
may differ from device to device depending on the number and location of
bad blocks on NAND.

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.

562b4e91d3 mtd: parsers: ofpart: fix parsing subpartitions
ofpart was recently patched to not scan random partition nodes as
subpartitions. That change unfortunately broke scanning valid
subpartitions like:

partitions {
	compatible = "fixed-partitions";
	#address-cells = <1>;
	#size-cells = <1>;

	partition@0 {
		compatible = "fixed-partitions";
		label = "bootloader";
		reg = <0x0 0x100000>;

		partition@0 {
			label = "config";
			reg = <0x80000 0x80000>;
		};
	};
};

Fix that regression by adding 1 more code path. We actually need 3
conditional blocks to support 3 possible cases. This change also makes
code easier to understand & follow.

2d751203aa mtd: parsers: ofpart: limit parsing of deprecated DT syntax
For backward compatibility ofpart still supports the old syntax like:
spi-flash@0 {
	compatible = "jedec,spi-nor";
	reg = <0x0>;

	partition@0 {
		label = "bootloader";
		reg = <0x0 0x100000>;
	};
};
(without "partitions" subnode).

There is no reason however to support nested partitions without a clear
"compatible" string like:
partitions {
	compatible = "fixed-partitions";
	#address-cells = <1>;
	#size-cells = <1>;

	partition@0 {
		label = "bootloader";
		reg = <0x0 0x100000>;

		partition@0 {
			label = "config";
			reg = <0x80000 0x80000>;
		};
	};
};
(we never officially supported or documented that).

Make sure ofpart doesn't attempt to parse above.

bb17230c61 mtd: parsers: ofpart: support BCM4908 fixed 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.
