This reverts commit 8f9cd1af0f9c325a902dbd0e79e12015372e6bb0.
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.

BCM63XX internal PHYs and BCM5365 SoC internal switch are both using the
same phy_driver->phy_id, causing conflicts and unnecessary probes. E.g
the BCM63XX phy internal IRQ is lost on the first probe.
The full BCM5365 UID is 0x00406370.
Use an additional byte to mask the BCM5365 UID to avoid duplicate driver
phy_id's. This will fix the IRQ issue in internal BCM63XX PHYs and avoid
more conflicts in the future.

Currently, the b53 MDIO switch driver registers the switch on
config-init and not on device probe. Because of this, the switch
gets added every time the associated interface comes up.
This commit fixes this behavior by registering the switch on device
probe.

Since kernel 4.1 bcm47xx_nvram_gpio_pin() is now defined in a global
header and can be safely called even on non-Broadcom platforms.
This change makes b53 look for "robo_reset" on ARCH_BCM_5301X and
slightly simplifies the code.

This adds initial support for kernel 4.14 based on the patches for
kernel 4.9.
In the configuration I deactivated some of the new possible security
features like:
CONFIG_REFCOUNT_FULL
CONFIG_SLAB_FREELIST_HARDENED
CONFIG_SOFTLOCKUP_DETECTOR
CONFIG_WARN_ALL_UNSEEDED_RANDOM
And these overlay FS options are also deactivated:
CONFIG_OVERLAY_FS_INDEX
CONFIG_OVERLAY_FS_REDIRECT_DIR
I activated this:
CONFIG_FORTIFY_SOURCE
CONFIG_POSIX_TIMERS
CONFIG_SLAB_MERGE_DEFAULT
CONFIG_WATCHDOG_HANDLE_BOOT_ENABLED
I am not sure if I did the porting correct for the following patches:
target/linux/generic/backport-4.14/020-backport_netfilter_rtcache.patch

Some devices (e.g. Tenda AC9 based on BCM47189B0) have BCM53125 with
port 5 connected to the second Ethernet interface on the SoC. In such
case there is no PHY and we need to force link manually.
This assumes port 5 can be marked as enabled for such devices. It's not
implemented yet unfortunately.

Our code was assuming CPU port uses the highest number. My BCM53573
device has eth0 connected to port 8 and eth1 connected to port 5. While
working on support for it I tried to:
1) Enable all ports (including port 8)
2) Set CPU port to 5
I noticed port 8 is not accessible anymore. It was just a development
process but it seems like something worth fixing anyway.

On two tested devices: Netgear R6250 (BCM53011 rev 2) and Luxul XWC-1000
(BCM53011 rev 3) it was possible to use port 7 and eth1 (instead of port
5 and eth0). It seems BCM53011 just like BCM53012 has 8 ports and
usually 3 of them are connected to the SoC.

On device reset the sizes for the vlan and port tables were wrongly
calculated based on the pointer size instead of the struct size. This
causes buffer overruns on 64 bit targets, resulting in panics.

At least on my b53 chip, the mask is 3 bits wide, and because
of this some STP states are not set properly and discarded when read.
Maybe for some other chips it makes sense to have just 2 bits width,
but I don't have other versions around to test/validate.
If that's the case then maybe we could add another STP state mask.

On BCM5301X there are two different cases to handle: CPU port 8 vs. any
other one. Support for CPU port 8 was already partially implemented but
it lacked setting some extra bit for 2G speed. It also will need to be
extended to implement "SMP dual core 3 GMAC setup". That's the reason
for handling it in separated code block.
This patch also adds overriding CPU port state for port other than 8. It
requires using recently defined GMII_PORT registers.
It was tested for regressions on BCM53011 revs 2 & 3. It was also
confirmed to fix switch on some internal Broadcom board.

For bcm63xx integrated switches, broadcom changed the data endianess
to match the system endianess. But this only applies to within one word,
which causes 48/64 bit values to be still split into their "litte endian"
groups.
E.g. 48 bit values (with 5 being the most significant byte) aligned
0x00 ..01 or 0123
0x04 2345 45..
will become
0x00 ..10 resp. 3210
0x04 5432 54..
Likewise for 64 bit values.
