e2aa04d1e5 kernel: mtk_bmt: add support for the bbt format used on mt7621
This does not have spare blocks for remapping, and it is also not suitable
for random write access. It only skips over bad blocks on linear writes of an
image to a partition. As such, it is really only suitable for the kernel
partition, or other partitions with mostly static data

2d19e6c6a4 generic: platform/mikrotik: use MTD notifier
If the SPI probe is sufficiently delayed, the routerboot driver may fail
to init as the routerboot partitions are not yet available.

Register an MTD user notifier instead of doing straight init so that the
init subroutines are only executed when the target MTD partitions are
present.

Because the init/exit routines can now be called outside of the kernel
normal init/exit calls, they cannot be jettisoned and must always be
available: the __init and __exit qualifiers are thus removed.

0b2c1d8b9a Move mvswitch 88E6060 driver to the ath25
ath25 requires a 88E6060 driver to support boards such as Fonera 2.0g
(FON2202). The swconfig based mvswitch driver has not yet been ported to
the 5.10 kernel as the only user is the ath25 target while all other
targets have been switched to the upstream DSA implementation.

Switching ath25 to the DSA implementation is a complex task, since we
need either per-board platform data or DTS support. ath25 lacks both of
them and builds only a single generic image. So we need to keep the
swconfig driver implementation to easly and quickly port ath25 to the
5.10 kernel.

Since porting the mvswitch driver to 5.10 as a generic driver is not an
option, and since the ath25 is its only user, make mvswitch a target
specific driver to be able to port it to the 5.10 kernel as part of the
kernel version update of the target. This will allow us quickly migrate
to the next kernel version and not delay the next firmware release.

b2cfed48f6 Revert "swconfig: fix Broadcom b53 support"
This reverts commit 8f9cd1af0f.

That commit was meant to add a single EXPORT_SYMBOL_GPL() but it
actually also added few .of_match_table-s. One commit should handle one
thing and should not introduce unrelated changes.

Regarding actual changes:
1. EXPORT_SYMBOL_GPL is not required as we don't build swconfig drivers
   as modules.
2. PHY drivers must not have .of_match_table. That is allowed for MDIO
   drivers. This could work for some time (although is didn't for me on
   bcm53xx) but does not with kernel 5.10. It causes a soft lockup and
   upstream developers confirmed it's an unsupported design.

kernel: support FIT partition parser on mtdblock devices
Allow using the FIT block-device partition partition parser to work on
top of mtdblock devices.
This is more tricky than it sounds as it requires to reorganize the
procedure of registering mtdblock devices in order to avoid locking
troubles caused by the block partition parsers then trying to open
the mtdblock device for reading while locks are still being held.
Fix that by moving the adding of the disks after the entire device
has been probed when locks no longer need to be held.
Also address issue with mtdsuper surfaced when using sub-partitions
which prevented mounting JFFS2 using the /dev/mtdblock* device.

kernel: mtdsplit_fit: support FIT with external data
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.

e6aac8d98f image: add support for building FIT image with filesystem
Allow for single (external-data) FIT image to hold kernel, dtb and
squashfs. In that way, the bootloader verifies the system integrity
including the rootfs, because what's the point of checking that the
hash of the kernel is correct if it won't boot in case of squashfs
being corrupted? Better allow bootloader to check everything needed
to make it at least up to failsafe mode. As a positive side effect
this change also makes the sysupgrade process on nand potentially
much easier as it is now.
In short: mkimage has a parameter '-E' which allows generating FIT
images with 'external' data rather than embedding the data into the
device-tree blob itself. In this way, the FIT structure itself remains
small and can be parsed easily (rather than having to page around
megabytes of image content). This patch makes use of that and adds
support for adding sub-images of type 'filesystem' which are used to
store the squashfs. Now U-Boot can verify the whole OS and the new
partition parsers added in the Linux kernel can detect the filesystem
sub-images, create partitions for them, and select the active rootfs
volume based on the configuration in FIT (passing configuration via
device tree could be implemented easily at a later stage).

This new FIT partition parser works for NOR flash (on top of mtdblock),
NAND flash (on top of ubiblock) as well as classic block devices
(ie. eMMC, SDcard, SATA, NVME, ...).
It could even be used to mount such FIT images via `losetup -P` on a
user PC if this patch gets included in Linux upstream one day ;)

41b867165d generic: platform/mikrotik: implement multi caldata
MikroTik recently changed again the way they store wlan calibration data
on devices. Prior to this change, ERD calibration data for all available
radios was stored within a single identifier node ("tag" in RouterBoot
parlance).

Recent devices have been seen with calibration (and BDF) data stored in
separate identifiers within LZOR packing for each radio: this patch
addresses this by:
1) ensuring that both variants are properly supported,
2) preserving backward compatibility with existing data consumers,
3) allowing for more than 2 calibration blobs to be exposed via sysfs.

Specifically, before this patch, the driver would provide a single sysfs
file named /sys/firmware/mikrotik/hard_config/wlan_data that contained
whatever calibration data found on the device's flash. After this patch,
when executed on a device that uses the old style storage, this behavior
is unchanged, but when executed on a device that uses new style storage
(for either traditional "ERD" packing or "LZOR" packing), the driver
replaces that single file with a folder containing one or more files
each containing the data encoded within individual identifiers.

As far as OpenWRT is concerned, this means that for devices which are
known to exist with both styles of data storage, a suitable hotplug stub
could look like this for e.g. the second radio:

wdata="/sys/firmware/mikrotik/hard_config/wlan_data"
( [ -f "$wdata" ] && caldata_sysfsload_from_file "$wdata" 0x8000 0x2f20 ) || \
( [ -d "$wdata" ] && caldata_sysfsload_from_file "$wdata/data_2" 0x0 0x2f20 )

This patch has been tested with LZOR old and new style packing on ipq4019,
and with old style on ath79.
