The Ethernet PHY's reset GPIO should be specified in the node of the PHY
itself, instead of the MAC (`fec`). The latter is deprecated, and was an
i.MX-specific extension, incompatible with the new reset controller
subsystem.

Reorganize the Curve25519 library code:
- Build a single libcurve25519 module, instead of up to three modules:
libcurve25519, libcurve25519-generic, and an arch-specific module.
- Move the arch-specific Curve25519 code from arch/$(SRCARCH)/crypto/ to
lib/crypto/$(SRCARCH)/. Centralize the build rules into
lib/crypto/Makefile and lib/crypto/Kconfig.
- Include the arch-specific code directly in lib/crypto/curve25519.c via
a header, rather than using a separate .c file.
- Eliminate the entanglement with CRYPTO. CRYPTO_LIB_CURVE25519 no
longer selects CRYPTO, and the arch-specific Curve25519 code no longer
depends on CRYPTO.
This brings Curve25519 in line with the latest conventions for
lib/crypto/, used by other algorithms. The exception is that I kept the
generic code in separate translation units for now. (Some of the
function names collide between the x86 and generic Curve25519 code. And
the Curve25519 functions are very long anyway, so inlining doesn't
matter as much for Curve25519 as it does for some other algorithms.)

Curve25519 is used only via the library API, not the crypto_kpp API. In
preparation for removing the unused crypto_kpp API for Curve25519,
remove the unused "curve25519-neon" kpp algorithm.
Note that the underlying NEON optimized Curve25519 code remains fully
supported and accessible via the library API.
It's also worth noting that even if the kpp support for Curve25519 comes
back later, there is no need for arch-specific kpp glue code like this,
as a single kpp algorithm that wraps the library API is sufficient.

There is an issue possible where TI AM33xx SoCs do not boot properly after
a reset if EMU0/EMU1 pins were used as GPIO and have been driving low level
actively prior to reset [1].
"Advisory 1.0.36 EMU0 and EMU1: Terminals Must be Pulled High Before
ICEPick Samples
The state of the EMU[1:0] terminals are latched during reset to determine
ICEPick boot mode. For normal device operation, these terminals must be
pulled up to a valid high logic level ( > VIH min) before ICEPick samples
the state of these terminals, which occurs
[five CLK_M_OSC clock cycles - 10 ns] after the falling edge of WARMRSTn.
Many applications may not require the secondary GPIO function of the
EMU[1:0] terminals. In this case, they would only be connected to pull-up
resistors, which ensures they are always high when ICEPick samples.
However, some applications may need to use these terminals as GPIO where
they could be driven low before reset is asserted. This usage of the
EMU[1:0] terminals may require special attention to ensure the terminals
are allowed to return to a valid high-logic level before ICEPick samples
the state of these terminals.
When any device reset is asserted, the pin mux mode of EMU[1:0] terminals
configured to operate as GPIO (mode 7) will change back to EMU input
(mode 0) on the falling edge of WARMRSTn. This only provides a short period
of time for the terminals to return high if driven low before reset is
asserted...
If the EMU[1:0] terminals are configured to operate as GPIO, the product
should be designed such these terminals can be pulled to a valid high-logic
level within 190 ns after the falling edge of WARMRSTn."
We've noticed this problem with custom am335x hardware in combination with
recently implemented cold reset method
(commit 6521f6a195c70 ("ARM: AM33xx: PRM: Implement REBOOT_COLD")).
It looks like the problem can affect other HW, for instance AM335x
Chiliboard, because the latter has LEDs on GPIO3_7/GPIO3_8 as well.
One option would be to check if the pins are in GPIO mode and either switch
to output active high, or switch to input and poll until the external
pull-ups have brought the pins to the desired high state. But fighting
with GPIO driver for these pins is probably not the most straight forward
approch in a reboot handler.
Fortunately we can easily control pinmuxing here and rely on the external
pull-ups. TI recommends 4k7 external pull up resistors [2] and even with
quite conservative estimation for pin capacity (1 uF should never happen)
the required delay shall not exceed 5ms.

Common name for Ethernet controllers is "ethernet", not "eth", also
recommended by Devicetree specification in "Generic Names
Recommendation". Verified lack of impact using dtx_diff.

All users of the generic vDSO library also use the generic vDSO datastore.
Remove the now unnecessary Kconfig symbol.

The cntvct_ok variable has not had any external user since commit
c7a18100bdff ("lib/vdso: Avoid highres update if clocksource is not
VDSO capable").
It also only has one user in vdso.c, once during init, so rather than
having the caller of patch_vdso() initialize cntvct_ok, just call
cntvct_functional() directly and avoid the global variable entirely.

Pull SoC fixes from Arnd Bergmann:
"These are mainly devicetree fixes for the rockchip and nxp platforms
on arm64, addressing mistakes in the board and soc specific
descriptions.
In particular the newly added Rock 5T board required multiple bugfixes
for PCIe and USB, while on the i.MX platform there are a number of
regulator related fixes. The only other platforms with devicetree
fixes are at91 with a fixup for SD/MMC and a change to enable all the
available UARTS on the Axiado reference board.
Also on the at91 platform, a Kconfig change addresses a regression
that stopped the DMA engine from working in 6.17-rc.
Three drivers each have a simple bugfix, stopping incorrect behavior
in op-tee firmware, the tee subsystem and the qualcomm mdt_loader.
Two trivial MAINTAINERS file changes are needed to make sure that
patches reach the correct maintainer, but don't change the actual
responsibilities"
