847990219c power-domain: Fix use of uninitialized value in dev_power_domain_ctrl
If dev_count_phandle_with_args returns 0 or another error, then pd will never
have been initialized by power_domain_get_by_index. Avoid comparing against
pd.dev in this situation.

467f0c4dc2 misc: atsha204a: Remove duplicate CRC-16 implementation
ATSHA204A uses bit-reversed checksum of standard CRC-16 with polynomial
x^16 + x^15 + x^2 + 1.

This ATSHA204A specific checksum can be calculated just by using common
U-Boot functions bitrev16() and crc16().

So replace custom driver CRC-16 implementation by common U-Boot functions.

  Call backtrace:
  Exception in kernel pc f8f8b5f0 signal 0

Inspection showed that gd->malloc_limit is zero. And it is because
generally SPL_FRAMEWORK initialize SPL's gd->malloc_limit. But when
SPL_FRAMEWORK is not enabled then in most cases nobody initialize
gd->malloc_limit and so SPL malloc simple does not work.

So disable SPL_SYS_MALLOC_SIMPLE by default when SPL_FRAMEWORK is not
enabled. SPL_SYS_MALLOC_SIMPLE can be disabled only by setting
SPL_SYS_MALLOC_F_LEN to zero. So do it.

This change fixes SPL error "alloc space exhausted" on P2020 board.

de70e8879b env: Implement lower priority arch_env_get_location()
Currently there is only one way to override desired environment location,
by implementing env_get_location(). This is increasingly being conflated
both on board level and architecture level, which leads to a problem on
boards where this function is already implemented on architecture level,
since those boards have no way to override this environment location on
board level anymore.

Implement arch_env_get_location() function which is architecture specific
and should only ever be implemented in architecture code. This function
has lower priority than env_get_location(), which should only ever be
implemented in board code, and which overrides the arch_env_get_location()
architecture environment selection.

This way, architecture can define its default environment chooser, while
board can now override it as needed at all times.

There is no functional change, since env_get_location() simply returns
arch_env_get_location(), and arch_env_get_location() implements the
current env_get_location() default content.

9e778c7ffc arm: mvebu: dts: uDPU: fix non-working networking
uDPU is a bit of a specific device in that it does not have any copper
ports nor any ethernet PHY-s but 2 SFP ports.

This is an issue since MVNETA requires a PHY phandle or a fixed-link to
be defined under its node.
Since U-boot has no SFP support this is reasonable in order to know how
to configure the MAC.

However this also means that networking does not work on uDPU at all
currently, and fails with:

uDPU>> dhcp
Could not get PHY for neta@30000: addr 0
phy_connect failed
Could not get PHY for neta@40000: addr 1
phy_connect failed

So, to provide working networking using only SFP-s let add the fixed-link
at 1G which is much more common than 2.5G SFP-s as well as disable the
TX_DISABLE pins like done on Armada 7040 and 8040 platforms.

Since uDPU is not using any of the GPIO-s on the SB controller for any
purpose other than GPIO, a call to the pinctrl must be made in order for
it to get probed and thus register the SB GPIO bank, otherwise SB GPIO-s
are not registered at all.

commands between CM3 and A53 cores.

Implement these Marvell fuse reading mbox commands via U-Boot fuse API.

Banks 0-43 are used for accessing Security OTP (44 rows with 67 bits via 44
banks and words 0-2).

Note that of the 67 bits, the 3 upper bits are: 1 lock bit and 2
auxiliary bits (meant for testing during the manufacture of the SOC, as
I understand it).

Also note that the lock bit and the auxiliary bits are not readable
via Marvell commands.

With CZ.NIC's commands the lock bit is readable.

Write support is not implemented yet.

10154b81de arm: mvebu: a37xx: Add support for reading NB and SB fuse OTP value
Implement reading NB and SB fuses of Armada 37xx SOC via U-Boot fuse API.

Banks 0-43 are reserved for accessing Security OTP (not implemented yet).
Bank 44 is used for accessing North Bridge OTP (69 bits via words 0-2).
Bank 45 is used for accessing South Bridge OTP (97 bits via words 0-3).

Write support is not implemented yet because it looks like that both North
and South Bridge OTPs are already burned in factory with some data. The
meaning of some bits of North Bridge is documented in WTMI source code.
The meaning of bits in South Bridge is unknown.

a37b68820c arm: mvebu: Fix Espressobin build for configs where ENV is not in SPI
When storing the UBoot Environment in for example EXT4,
the U-Boot build is broken for several reasons:
1. armada-385-turris-omnia-u-boot.dtsi will not allow
   CONFIG_ENV_OFFSET and CONFIG_ENV_SIZE to be undefined
2. armada-37xx/board.c ft_board_setup function does not
   exist if CONFIG_ENV_IS_IN_SPI_FLASH is not defined

This commit changes these files so that selecting a
different location for the environment is possible.

dd2b8c1155 cmd: gpio: Add gpio read subcommand
As explained in commit 4af2a33ee5 ("cmd: gpio: Make `gpio input`
return pin value again") the `gpio input` is used in scripts to obtain
the value of a pin, despite the fact that CMD_RET_FAILURE is
indistinguishable from a valid pin value.
To be able to detect failures and properly use the value of a GPIO in
scripts we introduce the `gpio read` command that sets the variable
`name` to the value of the pin. Return code of the `gpio read` command
can be used to check for CMD_RET_SUCCESS or CMD_RET_FAILURE.
CONFIG_CMD_GPIO_READ is used to enable the `gpio read` command.
