In the xrx200_close() function we call napi_disable(), that could
sleep, with priv->hw->chan[i].lock held. This could lead to deadlock
and causes the kernel to complain.
Look at the code I couldn't convince myself about why we
need to protect that specific code part with the lock. IMHO there
seems no reason to protect the refcount variables, because AFAIK
ndo_close() and ndo_open() callbacks are already called with a
semaphore held. Neither I could figure out why napi_disable() have to
be called with that lock held. The only remaining code part for
which I could guess the lock is useful for is ltq_dma_close()
function call.
This patch reduces the lock to the said function call, avoiding the
sleep-with-spinlock-held situation

The patch 0008 removes the vanilla kernel gptu.c of lantiq.
But the replacement file timer.c does not work Amazon-SE and
is also protected therefore with an CONFIG_SOC_AMAZON_SE :-)
This commit will re-activate the default vanilla kernel code
in gptu.c for Amazon-SE.

The generic SPI code calculates how long the issued transfer would take
and adds 100ms in addition to the timeout as tolerance. On my 500 MHz
Lantiq Mips SoC I am getting timeouts from the SPI like this when the
system boots up:
m25p80 spi32766.4: SPI transfer timed out
blk_update_request: I/O error, dev mtdblock3, sector 2
SQUASHFS error: squashfs_read_data failed to read block 0x6e
After increasing the tolerance for the timeout to 200ms I haven't seen
these SPI transfer time outs any more.
The Lantiq SPI driver in use here has an extra work queue in between,
which gets triggered when the controller send the last word and the
hardware FIFOs used for reading and writing are only 8 words long.

SMP state is generally affected by
- CONFIG_SMP build-time kernel configuration option and
- 'nosmp' runtime kernel commandline option
The SMP state within vpe-mt.c is determined by CONFIG_SMP option.
A runtime check is needed if VPE functionality
should be used with a kernel image that supports SMP.
This fix introduces a check for 'nosmp' command line option
if CONFIG_SMP kernel configuration option is enabled.
Note: This patch is needed to use lantiq FXS if CONFIG_MIPS_MT_SMP
(that activates CONFIG_SMP) is enabled within kernel configuration
and the 'nosmp' command line argument is given to disable SMP at runtime.
Without this patch CONFIG_MIPS_MT_SMP must be disabled before using FXS.
With this patch setting the 'nosmp' parameter is enough.
In general, concurrent usage of FXS and SMP
is incompatible and will cause kernel panics.

The two phy operation mode where one phy is assigned to an interface
without lantiq,* device tree property and the other phy is assigned to
an interface with the lantiq,wan device property was broken with the
multicast package leaks between vlans fixes.
Move the multicast packages relevant portmap settings to the condition
which handles multicast packages for better readability.
Replace the priv->port_map based port_map only for the interface which
has the lantiq,switch device tree property set, to allow tagged
multicast packages in two phy mode where the lantiq,switch device tree
property isn't used.

The ethernet driver uses a port map override via special tag to control
the ports on which multicast packets are sent. This was added to work
around an issue in the switch that was occasionally leaking packets onto
the wrong vlan.
Unfortunately the change had some leftover lines that were overwrting
the port map with a list of all ports, thus always leaking packets onto
the wront vlan.
Fix this by only enabling the override with the VLAN port map and only
if a matching VLAN port map was actually found
