441ee62931 ar71xx: remove AP83 reference design board support
This board is very old and unlikely to still be relevant today. Support
for it contains a significant amount of device specific baggage which is
worth getting rid of.

c312cef223 ar71xx: spi-rb4xx fix.
In new kernels we should use clk_prepare_enable instead of clk_enable
since clk_enable does not make proper initialization that leads
to rise WARN_ON messages and not working spi bus on the device.

59e7999a44 ag71xx: replace delay with sleep calls
I don't see that we're in an atomic context so there's no need to
busy-wait. Therefore replace the delay with sleep calls.
See also Documentation/timers/timers-howto.txt. It states:
"In general, use of mdelay is discouraged and code should
be refactored to allow for the use of msleep."

f5e5477c81 kernel: modify mtd related patches for 3.14
The change is the same as ("kernel/generic: modify mtd related
patches"). Since these files are under files directory, not a files
directory of specific kernel version, better to also change them. So
it will avoid adding files to future specific files directory
(e.g. files-3.14) for this mtd related change.

30ebad2dee ar71xx: ag71xx: increase calculated max frame length value
The r39147 commit introduces a regression: at lease on some routers
with ar8216 switch large packets get lost if 802.1q tagged port is
used on the interface connected to the aforementioned switch.

The r39147 changes code in the way so interface is set to accept
packets no longer than max ethernet frame length for a given mtu.

Unfortunately ar8216 has a feature: it sends two additional bytes
as a packet header and those this header needs to be added to the
max frame length. Otherwise long enough packets get lost.

The problem only manuifests itself if interface is used in vlan
tagged mode. If interface is untagged then ar8216's header fits
into space used by 802.1q tag and not packets are lost.

Include two additional bytes in the max frame length calculation
to fix the issue.

This patch is tested and works with Trendnet TEW-632BRP.

2b220f3550 ar71xx: ag71xx: fix max frame length setup of the built-in switches
The currently used bitmask of the maximum frame length field
is wrong for both models. On AR724x/AR933x the largest frame
size is 2047 bytes, on the AR934x it is 16383 bytes.

Make the MTU setup code model specific, and use the correct
bitmask for both models. Also change the value to the maximum.

Additionaly, disallow to change the MTU value while the
