These instructions are for 64-bit load/store. On ARMv5TE, the CPU
requires addresses to be aligned to 64-bit. When misaligned, behavior is
undefined (effectively either loads the same word twice on LDRD, or
corrupts surrounding memory on STRD).
On ARMv6 and newer, unaligned access is safe.
Removing these instructions for ARMv5TE is necessary, because GCC
ignores alignment information in pointers and does unsafe optimizations
that have shown up as bugs in various places.
This patch was originally added more than 11 years ago in commit b050f87d13,
but got lost 6 years ago, when gcc 9.1 was added in 88c07c6552.
This primarily affects the kirkwood and ixp4xx targets

Fix bootloop on TP-Link EAP615-Wall v1 by reducing LZMA dictionary
size. Before this patch and after an upgrade to kernel 6.12 this
device couldn't boot a kernel because of an error: "lzma compressed:
uncompress error 1".
I have chosen -d22 as dictionary size as suggested by @namiltd.
The usual sizes for problematic devices are -d16, -d20, -d22. I
have confirmed with my tests that this device can boot with a value
up to -d27, but there is no size benefit from values above -d21,
therefore -d22 is good enough.

There is some confusion in the Git log of this file. Specifically,
the commit message on 7b7f1702 incorrectly indicates that there was
"potential fear" about copyright infringement.
Upon review of this situation, there is, in my opinion, no concern of
copyright infringement here. This is not legal advice; it is my
opinion based of years of work on copyright policy for FOSS.
However, Elliott Mitchell's idea was obviously helpful as inspiration
in writing this script and deserves credit. Ideas alone, however,
are not to my knowledge copyrightable anywhere in the world.

With the switch to Linux 6.12 this driver was enabled by accident.
However, it doesn't support any of the router SoCs but is meant to be
used only by the smartphone, tablet and chromebook SoCs.
Disable the driver again to silence a kernel error logline during boot.

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>;
};

Partially revert commit 332645a610 ("uboot-mediatek: sync with
mtk-openwrt/u-boot 20250711") by dropping unused PHY drivers which come
with large embedded firmware (and are hence inacceptable for upstream)
and restoring our previous version of the Airoha EN8811H driver which is
known to work and load firmware from the eMMC boot1 hardware partition
instead of embedding it in the driver.
In future we may switch to the upstream Airoha EN8811H driver which
allows loading the firmware either from a filesystem or overloading the
en8811h_read_fw() for board which may eg. store that firmware directly
inside a eMMC hardware partition or UBI volume, like the BPi-R3 mini
does.
