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.

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.

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.

Simon Glass [Sun, 27 Mar 2022 20:26:20 +0000 (14:26 -0600)]
dm: core: Deal with a wrinkle with linker lists

When every member of a linker list is aligned by the compiler, we can no
longer rely on the sizeof of the struct to determine the number of
entries.

For example, if the struct size is 0x90 but every entry is aligned to 0xa0
by the compiler, the linker list entries takes more space in memory and
the calculation of the number of entries is incorrect. For example, we may
see 0x12 entries when there are only 0x11.

This is a real problem. There may be a general solution, although I cannot
currently think of one. So far it only bites with OF_PLATDATA_RT which
creates a pointer to each entry of the 'struct udevice' linker_list. This
does not happen without that option, so it only affects SPL.

Work around it by manually calculating the aligned size of struct udevice,
then using that for the n_ent calculation.

rockchip: rk3066: add clock driver for rk3066 soc

Add the clock driver for the rk3066 platform.

Derived from the rk3288 and rk3188 driver it
supports only a bare minimum to bring up the system
to reduce the TPL size for:
  SDRAM clock configuration.
  The boot devices NAND, EMMC, SDMMC, SPI.
  A UART for the debug messages (fixed) at 115200n8.
  A SARADC for the recovery button.
  A TIMER for the delays (fixed).

There's support for two possible frequencies,
the safe 600MHz which will work with default pmic settings and
will be set to get away from the 24MHz default and
the maximum of 1.416Ghz, which boards can set if they
were able to get pmic support for it.

After the clock tree is set during the TPL probe
there's no parent update support.

In OF_REAL mode the drivers ns16550.c and dw-apb-timer.c
obtain the (fixed) clk_get_rate from the clock driver
instead of platdata.

The rk3066 cru node has a number of assigned-clocks properties
that call the .set_rate() function. Add them to the list so that
they return a 0 instead of -ENOENT.
