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.

CONFIG_FORTIFY_SOURCE=y is already set in the generic kernel
configuration, but it is not working for MIPS on kernel 5.4, support for
MIPS was only added with kernel 5.5, other architectures like aarch64
support FORTIFY_SOURCE already since some time.
This patch adds support for FORTIFY_SOURCE to MIPS with kernel 5.4,
kernel 5.10 already supports this and needs no changes.
This backports one patch from kernel 5.5 and one fix from 5.8 to make
fortify source also work on our kernel 5.4.
The changes are not compatible with the
306-mips_mem_functions_performance.patch patch which was also removed
with kernel 5.10, probably because of the same problems. I think it is
not needed anyway as the compiler should automatically optimize the
calls to memset(), memcpy() and memmove() even when not explicitly
telling the compiler to use the build in variant.
This increases the size of an uncompressed kernel by less than 1 KB.

AR2315 Ethernet driver pass NULL instead of a real device pointer to DMA
(un-)map calls. With kernel version 5.4 such behaviour causes a kernel
panic. Fix this issue by preserving device pointer during the probe
procedure and pass it to each skb data DMA (un-)map call.

Rework ethernet supported link modes to linkmode bitmask.
This is needed to suppress compilation errors:

Kernel commit e7bfb3fdbde3 ("mtd: Stop updating erase_info->state
and calling mtd_erase_callback()") removed erase_info->state
updates and calls of mtd_erase_callback().
Drop these erase callback invocations from AR2315 MTD driver as well.

Discussion on the mailing list reveals that this target has active
users. As we are finally able to upgrade this target to kernel 5.4,
add it back to master.
This reverts commit 7d29a55714 ("ath25: drop target") and
immediately moves the relevant files to 5.4, without touching
the content.
