On most image types the rootfs ends at an erase-block. However, at least
with brnImages this is not the case: while the partitions are aligned
with the erase-block size there is a 12 byte footer at the end of the
partition which must not be touched by any filesystem. This lead to a
rootfs_data partition which was not aligned properly (and thus ended up
being readonly):
0x000000480000-0x00000085a800 : "rootfs_data" (128 KiB EB)

This allows splitting EVA images (usually found in fritz devices). The
firmware will be split into a kernel and a separate rootfs partition.

This adds brnImage (used with the brnboot bootloader) firmware parsing
support. brnboot verifies the integrity of the firmware stored on the
"Code Image" partitions by looking at the 12 byte footer at the very end
of the partition. This footer contains the checksum of the original
brnImage (kernel + rootfs/squashfs) and must not be touched (by our JFFS2
rootfs_data - otherwise the image will not be bootable anymore).
Big thanks to Mathias Kresin for analyzing the brnImage structure and
finding out the information how to keep images valid even when adding a
nested rootfs_data partition.

Given those patches are relevant to any ARC platform and even
ISA version it makes perfect sense for patches to exist
in one place instead of being duplicated for each new ARC-based ASIC.
Note this is a prerequisite for upstreaming of ARC HS38 support in
OpenWRT.

Some switches can force link speed for a port. Let's add API that will

This fixes regression introduced in my recent ledtrig-netdev commit.
Events triggered by different interfaces were stopping timer so it
wasn't working for tx/rx mode.

The ppp0 interface is renamed after the connection is established. Due
to a missing NETDEV_REGISTER event, the ledtrig-netdev isn't aware of
the renamed interface and literally ignores the device
(no tx/rx indication, led isn't switched off with 'ifdown wan').

As explained earlier, using SWITCH_TYPE_LINK gives more flexibility,
it doesn't require e.g. string parsing to read some data.

So far we were sending link data as a string. It got some drawbacks:
1) Didn't allow writing clean user space apps reading link state. It was
needed to do some screen scraping.
2) Forced whole PORT_LINK communication to be string based. Adding
support for *setting* port link required passing string and parting
it in the kernel space.

We may just delete timer on every trigger update and then start it again
if needed. This will let us avoid both: races and locking in frequently

All supported kernels require patching ledtrig-netdev in the same way,
so it's safe to just move these changes to the base version of this
driver. We needed these patches for some old kernels 2.6.36 and 3.11.

In r45970 the MAC swap handling was made opt-in, however some boards
have been forgotten during the conversion. Since the reference design
uses this MAC swapping, and pretty much all known boards using this chip
seem to do so too, enabling the swapping is a more reasonable default
than leaving it disabled.
Change the code to still allow boards to opt-out of this.

In old days mtd_add_partition was checking for partitions overlapping
which was breaking our splitting feature. We had to modify this function
by adding an extra bool dup_check parameter. Upstream commit:
3a434f66e6da ("mtd: part: Remove partition overlap checks")
removed that check so we don't need our modification anymore.

For a long time we have a dedicated firmware splitter for uimage as a
replacement for the one builtin into mtd subsystem. For a year we got a
proper warning for users sticking to the old one (r43700). It should be
really safe to drop it now, especially since we do it for 4.4 only.
