This adds basic support for the Turris Mox board from CZ.NIC, which is
currently being crowdfunded on Indiegogo.
Turris Mox is as modular router based on the Armada 3720 SOC (same as
EspressoBin).
The basic module can be extended by different modules. The device tree
binary for the kernel can be dependent on which modules are connected,
and in what order. Because of this, the board specific code creates
in U-Boot a variable called module_topology, which carries this
information.

This adds support for the CPU watchdog found on Marvell Armada 37xx
SoCs.
There are 4 counters which can be set as CPU watchdog counters.
This driver uses the second counter (ID 1, counting from 0)
(Marvell's Linux also uses second counter by default).
In the future it could be adapted to use other counters, with
definition in the device tree.

The drivers are based on Linux driver by Gregory Clement.
The TBG clocks support only the .get_rate method.
- since setting rate is not supported, the driver computes the rates
when probing and so subsequent calls to the .get_rate method do not
read the corresponding registers again
The peripheral clocks support methods .get_rate, .enable and .disable.
- the .set_parent method theoretically could be supported on some clocks
(the parent would have to be one of the TBG clocks)
- the .set_rate method would have to try all the divider values to find
the best approximation of a given rate, and it doesn't seem like
this should be needed in U-Boot, therefore not implemented

This is needed for Armada 37xx.
This introduces new device tree bindings. AFAIK there is currently no

Xilinx ZynqMP also contains dual Cortex R5 which can run U-Boot.
This patch is adding minimal support to get U-Boot boot.
U-Boot on R5 runs out of DDR with default configuration that's why
DDR needs to be partitioned if there is something else running on arm64.
Console is done via Cadence uart driver and the first Cadence Triple
Timer Counter is used for time.
This configuration with uart1 was tested on zcu100-revC.

Mask HRESET_B after cleared the the RCW_SRC, because in the workaround
we override the RCW_SRC and if HRESET_B is issued after the override
then SoC cannot find valid RCW as the RCW_SRC was overwritten and
result in hang. So we need to mask HRESET_B in case user asserts it,
and the PORESET_B should be asserted which leads to resampling of
cfg_rcw_src pins and loading of correct RCW_SRC.

JR3 was getting removed from device tree only if random number
generation was successful. However, if SEC firmware is present,
JR3 should be removed from device tree node irrespective of the
random seed generation as SEC firmware reserves it for it's use.
Not removing it in case of random number generation failure causes
the kernel to crash.
Random number generation was being called twice. This is not
required. If SEC firmware is running, SIP call can be made to the SEC
firmware to get the random number. This call itself would return
failure if function is not supported. Duplicate calling of random
number generation function has been removed.

The Arria10 uses slightly different boot image header than the Gen5 SoCs,
in particular the header itself contains an offset from the start of the
header to which the Arria10 jumps. This offset must not be negative, yet
the header is placed at offset 0x40 of the bootable binary. Therefore, to
jump into U-Boot, add a trampoline just past the Arria10 boot header and
point to this trampoline at fixed offset from the header generated using
the mkimage -T socfpgaimage_v1 . Note that it is not needed to jump back
to offset 0x0 of the image, it is possible to jump directly at the reset
label and save processing two instructions.
