Rework each affected mtdsplit driver to make use of -ENOENT error
instead of -ENODEV to handle new kernel that checks error from parser on
subpartitions.
The only acceptable error is -ENOENT that skip the parser. This follow
pattern used upstream and also by an mtdsplit parser, mtdsplit_bcm_wfi,
and also by a workaround currently implemented for mtdsplit_mstc_boot.

Linux Kernel 6.7 and later versions handle all errors returned by mtd

Currently the detection of external-data FIT images works by checking
if the FIT structure is more than 4 kiB. However, for boards with lots
of different DT-overlays and configurations the FIT structure can
exceed 4 kiB which results in the FIT splitter to fail detecting the
rootfs.
Increase the threshold for external-data FIT to 512 kiB as there aren't
any kernel images smaller than that, and FIT structure less than 512 kiB
will always be an external-data FIT.

Since Linux 6.7, introduced with commit 5c2f7727d437 ("mtd: mtdpart:
check for subpartitions parsing result"), errors during subpartition
parsing cause all MTD partitions to be torn down.
Since the current mtdsplit driver for devices using H3C VFS returns
-EINVAL if it does not find a file system containing an OpenWrt image,
this makes initial installation of OpenWrt impossible.
Work around this by returning 0 when the file system contains unexpected
data. Also print a message in this case to show what is going on.

Add new mtdsplit parser "mstc-boot" for the devices manufactured by MSTC
(Mitra Star Technology Corp.). This is necessary to handle dual-boot on
those devices.
This parser splits kernel+rootfs or only rootfs(or UBI) based on the
image in the firmware partition or pre-defined partitions in dts, and
"bootnum" value in the "persist" (or "working") partition.
Note: "bootnum" is used for switching active firmware partitions on the
devices manufactured by MSTC and '1' or '2' are used on most
devices. But some devices use '0' or '1'. (example: I-O DATA
WN-DEAX1800GR)
Sequence:
1. obtain "bootnum" value
2. child nodes exsist (regardless of bootnum)
-> fixed partitions
(active parts : without bootnum (ex.: "kernel", "rootfs")
inactive parts: with bootnum (ex.: "kernel2", "rootfs2"))
3. current partition is active (dt bootnum == mtd bootnum)
-> image-based partitions
Device Tree:
- common
- mstc,bootnum : "bootnum" value for the mtd partition (0/1/2)
- mstc,persist : phandle of "persist" partition containing "bootnum"
value
- fixed partitions
- #address-cells: indicate cell count of address of child nodes (1)
- #size-cells : indicate cell count of size of child nodes (1)
- (child nodes) : define the child partitions
- reg : define the offset and size
- label-base : define the base name of the partition
- (example) : base:"kernel"->"kernel"(active)/"kernel2"(inactive)
example:
partition@3c0000 {
compatible = "mstc,boot";
reg = <0x3c0000 0x3240000>;
label = "firmware1";
mstc,bootnum = <1>;
mstc,persist = <&mtd_persist>;
#address-cells = <1>;
#size-cells = <1>;
partition@0 {
reg = <0x0 0x800000>;
label-base = "kernel";
};
partition@800000 {
reg = <0x800000 0x2a40000>;
label-base = "ubi";
};
};
- image-based partitions
(no additional properties)
example:
partition@5a0000 {
compatible = "mstc,boot";
label = "firmware1";
reg = <0x5a0000 0x3200000>;
mstc,bootnum = <1>;
mstc,persist = <&mtd_persist>;

The bootloader on some H3C devices (for example HPE 1920 switches) only
supports booting from flash by reading an image from an "VFS" filesystem
which spans most of the available flash. The filesystem size is hard-
coded in the bootloader. However, as long as no write operations are
performed in the bootloader menu, it is sufficient if the start of the
partition contains a valid filesystem with the kernel image.
This mtdsplit parser reads the size and location of the kernel image and
finds the location of the rootfs stored after it. It assumes that the
filesystem image matches the layout of one generated by mkh3cvfs, with
a filename of "openwrt-kernel.bin" for the kernel image.

U-Boot has recently added support for having data blobs in uImage.FIT
images stored at offsets after the FDT structure rather than embedding
the data into the FDT structure itself. This is useful as it allows
parts of the image to be mapped by the FIT partition parser, and it
allows the FIT structure itself to be parsed more easily as it usually
fits into single page.
mtdsplit_fit assumed that the total length of an image is identical
to the length of the FDT structure. For uImage.FIT with external data
this assumption no longer holds true.
Add support for uImage.FIT with external data to mtdsplit_fit and in
in that case only split-off rootfs_data -- selecting and mapping rootfs
partition is left to the block partition parser just like on UBI and
block/GPT based platforms.
