According to the calling convention of the o32 ABI the
caller function must reserve stack space for $a0-$a3
registers in case the callee needs to save its arguments.
The assembly startup code does not reserve stack space
for these registers thus when the main C function needs
to save its arguments, that will cause a stack overflow.
Fix the assembly code to reserve stack space for the
registers to avoid that.
Compile tested only.

Instead of using our patch-dtb program just place the device tree

This also adds support for having the device tree file in the boot

With the backport of the kernel 4.5 pinctrl-xway patches (3551609d &
826bca29) the pinmux group "spi" was splitted into "spi_di", "spi_do" &
"spi_clk". But the no longer existing group "spi" is still used by some
device tree source files.
This fixes the detection of the wireless chipset of the VGV7510KW22.

The stock u-boot doesn't disable unused flash banks. Therefore, the nand
driver tries to initialize a not connected NOR flash and the device
hangs on boot.
Workaround the issue by selecting the second flash bank (NAND).

r48381 added CONFIG_MTD_SPLIT_UIMAGE_FW=Y to the lantiq kernel
configuration. That unfortunately contains a typo since the "y" has to
be lower-case. This leads to the kernel asking whether the config
symbol should be enabled and thus breaking the build.

Until linux 4.1 the lantiq target used CONFIG_MTD_UIMAGE_SPLIT=y. That
option however is only available until linux 4.3 - thus it was not added
to lantiq's 4.4 kernel config (in r48307). This results in broken images

The following patches were dropped because they are already applied
upstream:
- 0038-MIPS-lantiq-fpi-on-ar9.patch

- 0042-USB-DWC2-big-endian-support.patch

All other patches were simply refreshed, except the following:
- 0001-MIPS-lantiq-add-pcie-driver.patch
Changes to arch/mips/lantiq/xway/sysctrl.c (these changes disabled
some PMU gates for the vrx200 / VR9 SoCs) were removed since the
upstream kernel disables unused PMU gates automatically (since
95135bfa7ead1becc2879230f72583dde2b71a0c
"MIPS: Lantiq: Deactivate most of the devices by default").
- 0025-NET-MIPS-lantiq-adds-xrx200-net.patch
Since OpenWrt commit 55ba20afcc2fe785146316e5be2c2473cb329885 drivers

available for drivers anymore since it's called automatically within
of_get_mac_address().

Compared to the "old" driver:
- Each device must assign a pinctrl setting to the SPI node to allow the
new SPI driver to configure the SPI pins.
While here we are also using separate input and output settings so we
are independent of whether the bootloader configures the pins correctly.
- We use the new "compatible" strings to make the driver choose the
correct number of chip-selects for each SoC.
- The new driver starts counting the chip-selects at 1 (instead of 0, like
the old one did). Thus we have to adjust the devices accordingly.

SVN-Revision: 48293
The new driver provides a few improvements over the old one:
- Separate compatible strings per SoC type (this allows removing some
hardcoded of_device_is_compatible() checks)
- It does not rely upon spi-bitbang anymore
- chip-selects are numbered as in the datasheet (= starting at 1 instead
of 0)

After the latest pinctrl backports there are only 50 (instead of 56 as
before) GPIOs/pins exported (thus the first GPIO on VRX200 SoCs is now
462, before it was 456). This means that any hardcoded GPIOs have to be
adjusted.
This broke the PCIe driver (which seems to be the only driver which uses
hardcoded GPIO numbers), it only reports:
ifx_pcie_wait_phy_link_up timeout
ifx_pcie_wait_phy_link_up timeout
ifx_pcie_wait_phy_link_up timeout
ifx_pcie_wait_phy_link_up timeout
ifx_pcie_wait_phy_link_up timeout
pcie_rc_initialize link up failed!!!!!
To prevent more of these issues in the future we remove the hardcoded
PCIe reset GPIO definition and simply pass it via device-tree (like the
PCI driver does).

These were introduced in upstream commit
be14811c03cf "pinctrl/lantiq: introduce new dedicated devicetree
bindings" and finally allow us to use the individual pins within our dts
(for example spi_clk, etc.).
Please note that this changes the number of GPIOs which are available for
some SoCs. VRX200 SoCs for example only have 50 pins, but previously 56
pins were exposed. This means that all places which are using hardcoded
GPIO numbers (which are not passed via device-tree) need to be adjusted
(because the first GPIO number is now 462, instead of 456).

Upstream commit be14811c03cf2 "pinctrl/lantiq: introduce new dedicated
devicetree bindings" allows us to use each pin in the pinmux. This is
useful for example in the "spi" group which contains some pins which
are inputs, and some which are outputs.
These can only be used once the new compatible strings for the pinctrl
node are used.
Additionally 0150-lantiq-pinctrl-xway.patch and the "GPIO PORT3 fix"
(which was part of 0012-pinctrl-lantiq-fix-up-pinmux.patch) were
replaced with their upstream variants which are also in 4.5.
