254ccf9f4c lantiq: fix an ethernet stability issue triggered by receving packets during boot
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
disabled, and it can be easily reproduced by rebooting while sending a
flood ping to the broadcast address.

24c06e2481 lantiq: fix spurious irq storm
Since the MIPS IRQ stack patches, lantiq devices were emitting a storm
of messages like this:

[  567.872172] Spurious IRQ: CAUSE=0x1100c300

Fix this by reworking the IRQ dispatch code

f036956e1f lantiq: update USB controller initialization
This adds USB initialization fixes for Danube, Amazon SE and xrx300 and
should fix the clock on at least Danube which hopefully closes FS#351.

The xrx200 usb driver now uses more memory for the dwc2 fifos, this was
increased in the chip compared to ar9.

This is based in part on the vendor documentation and the vendor code
base as a reference.

860210c373 lantiq: backport kernel patch to pass of node to nand_dt_init
Backport upstream commit a61ae81a1907af1987ad4c77300508327bc48b23.

The actually purpose of the patch was to do some cleanup. As a side
effect of this cleanup, the device node is now passed to nand_dt_init.

This allows to use the common nand device tree properties

 - nand-bus-width
 - nand-on-flash-bbt
 - nand-ecc-mode
 - nand-ecc-step-size
 - nand-ecc-strength

for the plat_nand driver.

07bc0d6089 lantiq: fix pci issue if mem kernel parameter is used
As specified by e0229a16b0 if the VR9
based router provides FXS ports and they should enabled then the
following must added to the kernel command line:

  mem=[TOTALMEMSIZE-2M] vpe1_load_addr=ADDRESS vpe1_mem=2M

By adding mem= parameter a pci device stop working correctly. The
pci-lantiq.c module use get_num_physpages() to compute dynamically the
memory amount of the board.

The mem= make the module to compute in the wrong way the BAR11MASK, so
in this situation the mask is misaligned with the dma area that the
hardware expects.

This patch is a port of what legacy ifxmips_pci.c does.

e0229a16b0 lantiq: added support for VPE1
Created minimal patchset based on BB rev 43158 by Eddi De Pieri
14.07/openwrt.git 79472c025449efae9310defad0d3a73cff14d756

If the VR9 based router provides FXS ports and they shoud enabled then
the following must added to the kernel command line:
mem=[TOTALMEMSIZE-2M] vpe1_load_addr=ADDRESS vpe1_mem=2M maxvpes=1
maxtcs=1

To use FXS 2M of RAM are needed for the VPE firmware. The size is set
by vpe1_mem.
The available RAM must be reduced by this size using the mem argument.
A correct load address (example 0x83e00000) for the firmware must be given,

23e3314cad lantiq: fix thermal sensors driver
Read the temperature including the decimale place from the CGU_GPHY1_CR
register.

Decrement the temperature read from the register by 38.0 degree celsius.
The temperature range of the sensor is -38.0 to +154 °C and the register
value 0 is equal to -38.0 °C. This fixes the report of unrealistic
temperatures as seen on all tested boards.

Give the SoC a few milliseconds to get the first temperature value. On
some rare occasions there is no temperature value in the register when
read the first time after activation. This leads to a reported
temperature of -38.0 °C on boot.

Only version 1.2 of the vr9 SoC has a temperature sensor. Add a check
to make sure the driver doesn't load on v1.1 vr9 SoCs.

bf32177a1d kernel: remove full cache flush in fuse_copy_do() for MIPS
This patch was introduced in commit r16412 for the brcm47xx target only
and then moved to generic in commit r32395. It was initially added
because of ticket #5186 and should fix some problems with fuse file
systems and MIPS caches. The commit comment in r32395 says that this a
generic problem in MIPS CPUs, but does not name any specifics about
that. There was a fix added to kernel 2.6.21 in commit commit
7575a49f20 "[MIPS] Implement flush_anon_page()." that should fix this
problem, but that was already available before both commits were done
to OpenWrt.

I just tested fuse with ntfs.3g without this patch on a BCM4704
(BMIPS3300 V0.6) SoC and haven't seen any problems. Someone reported
that removing this patch improves some fuse operations by 5 times on
some modern MIPS cores.
My test was only a simple "dd if=/dev/zero of=/mnt/zero bs=5000" to an
USB stick.

This patch removes the patch to OpenWrt, because I assume that it is
not needed any more and Felix, the orginal author, also thinks so.
