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.

Refresh patches. A number of patches have landed upstream & hence are no
longer required locally:
062-[1-6]-MIPS-* series
042-0004-mtd-bcm47xxpart-fix-parsing-first-block
Reintroduced lantiq/patches-4.4/0050-MIPS-Lantiq-Fix-cascaded-IRQ-setup
as it was incorrectly included upstream thus dropped from LEDE.
As it has now been reverted upstream it needs to be included again for
LEDE.

Make switch port LEDs blink on activity as they do with stock firmware.
The u-boot loader sets suitable values in the LED control register that
unfortunately get blown away by the linux switch driver init. Restore
that value by using driver 'initvals'. 0x0431 is the led control
register, the value 0x0960. Each nybble represents each LED's mode
(LED3,2,1,0) in this case OFF, 1000LINK+Activity, 100/10LINK+Activity,
OFF. Only LED1&2 are physically present.
Enabling the blinkenlights exposed the fact that an RRCP packet was
being emitted by the switch on all ports every second. Further initvals
copied from stock firmware's u-boot driver disabled this 'feature'.

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.

Signed-off-by: Mathias Kresin <dev@kresin.me>
Using the lantiq,wan device tree property for one interface node and
the lantiq,switch device tree property for another interface node at
the same time was never intended/isn't supported at the moment.
The property is meant to be used in 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 to have two netdevs.
If both properties are used at the same time, the lantiq,wan interface
is shown as independent netdev but not able to operate independent. The
port needs to be managed via swconfig. These dependency is not obvious
and fooled already a lot of users.
Add a default WAN vlan for xrx200 devices having an ethernet WAN port
and remove the lantiq,wan device tree property. Leave it up to the user
to set the ethernet WAN port as default WAN interface or to use this
port as additional LAN port.

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 ASL56026 is a VDSL2 router with dual 100mbit ethernet,
also known as the ECI B-FOCuS V-2FUb/I.
CPU: Lantiq XRX268 v1.1 at 333MHz
Modem: Lantiq VRX208
RAM: 32MiB DDR2 at 167MHz
Flash: 8MiB NOR, Spansion S29GL064N90TF04
UART is at JP1:
Pin 1 TX
Pin 2 GND
Pin 3 +3.3V
Pin 4 NC
Pin 5 RX
Boot selection pins are exposed via several resistor jumpers:
boot_sel0 is at J15, on the rear of the board. Default is high.
boot_sel1 is at J3, next to the flash - it is also the flash CE# pin. Default is low.
boot_sel2 is at J12, directly below the SoC. Default is low.
boot_sel3 is at J16, on the rear of the board. Default is low.
The boot_sel pins should never be shorted, the jumper must be moved or
a lower value resistor used to change the pull (existing resistors are 4k7, 1k should work)
To install with the stock bootloader you must break the built in image selection process
which uses at least the following vars: f_upgrade_addr, f_upgrade2_addr, loadaddr, kernel_addr, activeregion, committedregion
This is done by setting loadaddr and both f_upgrade_addr vars to the same address:
VR9 # setenv loadaddr 0xB0040000
VR9 # setenv f_upgrade_addr 0xB0040000
VR9 # setenv f_upgrade2_addr 0xB0040000
VR9 # saveenv
Then flash the firmware image:
VR9 # tftpboot 0x81000000 lede-lantiq-xrx200-ASL56026-squashfs-sysupgrade.bin
VR9 # erase B0040000 +${filesize}

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

Disabling ethernet during reboot (only to enable it again when the
ethernet driver attaches) can put the chip into a faulty state where it
corrupts the header of all incoming packets.
This happens if packets arrive during the time window where the core is

flood ping to the broadcast address.
