On of the MiniPCIe ports on Turris Omnia is also a mSATA port. Whether
it works in SATA or PCIe mode is determined by a strapping pin, which
value is read from the MCU.
We already determine which type of card is connected when configuring
SerDeses.
But until now we left both SATA and PCIe port 0 nodes in device tree
enabled, and so the SATA driver is probed in U-Boot / Linux even if we
know there is no mSATA card, and similarly PCIe driver tries to link on
port 0 even if we know there is mSATA card, not a PCIe card.
Fixup device tree blob to disable SATA node if mSATA card is not
present, and to disable PCIe port 0 node if mSATA card is present.
Do this for U-Boot's DT blob before relocation and also for kernel DT
blob before booting.
This ensures that software does not try to use SATA or PCIe HW when
corresponding PHY is not configured.

Commit aeb0ca64db ("arm: mvebu: turris_omnia: disable MCU watchdog in
SPL when booting over UART") disabled MCU watchdog when booting over
UART to ensure that watchdog does not reboot the board before UART
transfer finishes.
But if UART transfer fails for some reason, or if U-Boot binary crashes,
then board hangs forever as there is no watchdog running which could
reset it.
To fix this issue, enable A385 watchdog with very high timeout before
disabling MCU watchdog to ensure that even slow transfer can finish
successfully before watchdog timer expires and also to ensure that if
board hangs for some reason, watchdog will reset it.
Omnia's MCU watchdog has fixed 120 seconds timer and it cannot be
changed (without updating MCU firmware). A385 watchdog by default uses
25 MHz input clock and so the largest timeout value (2^32-1) can be
just 171 seconds. But A385 watchdog can be switched to use NBCLK (L2) as
input clock (on Turris Omnia it is 800 MHz clock) and in this case final
watchdog clock frequency is calculated as:
freq = NBCLK / 2 / (2 ^ R)
So A385 watchdog on Turris Omnia can be configured to at most 1374
seconds (about 22 minutes). We set it to 10 minutes, which should be
enough even for bigger U-Boot binaries or slower UART transfers.
Both U-Boot and Linux kernel, when initializing A385 watchdog, switch
watchdog timer to 25 MHz input clock, so usage of NBCLK input clock in
U-Boot SPL does not cause any issues.

There is a Factory RESET button on the back side of the Turris Omnia
router. When user presses this button before powering the device up and
keeps it pressed, the microcontroller prevents the main CPU from booting
and counts how long the RESET button is being pressed (and indicates
this by lighting up front LEDs).
The idea behind this is that the user can boot the device into several
Factory RESET modes.
This patch adds support for U-Boot to read into which Factory RESET mode
the user booted the device. The value is an integer stored into the
omnia_reset environment variable. It is 0 if the button was not pressed
at all during power up, otherwise it is the number identifying the
Factory RESET mode.
This patch also changes bootcmd to a special hardcoded value if Factory
RESET button was pressed during device powerup. This special bootcmd
value sets the colors of all the LEDs on the front panel to green and
then tries to load the rescue image from the SPI flash memory and boot
it.

This patch tries to implement a generic watchdog_reset() function that
can be used by all boards that want to service the watchdog device in
U-Boot. This watchdog servicing is enabled via CONFIG_WATCHDOG.
Without this approach, new boards or platforms needed to implement a
board specific version of this functionality, mostly copy'ing the same
code over and over again into their board or platforms code base.
With this new generic function, the scattered other functions are now
removed to be replaced by the generic one. The new version also enables
the configuration of the watchdog timeout via the DT "timeout-sec"
property (if enabled via CONFIG_OF_CONTROL).
This patch also adds a new flag to the GD flags, to flag that the
watchdog is ready to use and adds the pointer to the watchdog device
to the GD. This enables us to remove the global "watchdog_dev"
variable, which was prone to cause problems because of its potentially
very early use in watchdog_reset(), even before the BSS is cleared.

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.
In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.
