On request/suggestion from Simon Glass back in May 22 2019 [1], the
'strsep' mechanism implemented in bcb_set() was set to work directly
with user-provided argv strings, to avoid duplicating memory and for
the sake of simpler implementation.
However, since we recently exposed bcb_write_reboot_reason() API to be
called by U-Boot fastboot, the idea is to be able to pass const string
literals to this new BCB API, carrying the reboot reason.
Since 'strsep' (just like its older/superseded sibling 'strtok')
modifies the input string passed as parameter, BCB command in its
current state would attempt to perform in-place modifications in a
readonly string, which might lead to unexpected results.
Fix the above with the cost of one dynamic memory allocation ('strdup').
This will also ensure no compiler warnings when passing string literals
to bcb_write_reboot_reason().

Fastboot is evolving and beginning with commit [1], the
upstream implementation expects bootloaders to offer support for:
- reboot-recovery
- reboot-fastboot
The most natural way to achieve the above is through a set of
pre-defined "reboot reason" strings, written into / read from
the BCB "command" field, e.g.:
- bootonce-bootloader [2]
- boot-fastboot [3]
- boot-recovery [4]
Expose the first 'bcb' API meant to be called by e.g. fastboot stack,
to allow updating the BCB reboot reason via the BCB 'command' field.

The UEFI Self Certification Test (SCT) checks the SetTime() service with
the following steps:
* set date
* reset
* check date matches
To be compliant the sandbox should keep the offset to the host RTC during
resets. The implementation uses the environment variable
UBOOT_SB_TIME_OFFSET to persist the offset.

At present if these calls are used with of-platdata, a confusing error is
produced, referring to a function not actually called by the code causing
the problem.
Fix this by not inlining, so that the error mentions the dev_read_...()
function and it is more obvious what is going on.

The EC can store small amounts of data for the benefit of the

It is useful to be able to figure out which phase we are loading next and
which phase we came from. Add some functions to handle this as well as
returning the name of a phase. This allows messages like "Booting to x"
where x is the next phase.
At present, TPL says 'Jumping to U-Boot' at the end, when in fact it is
jumping to SPL. This is confusing, so use the new functions to correct
this.
Tests for this will come with an upcoming minor SPL test refactor.

Signed ARM_SMCCC_FAST_CALL value is shifted to 31'st bit. Then, it is expanded
to 64 bit value, which results in 1s in higher 32 bits.
This causes corrupted values in 64-bit SMC IDs and issues in buggy handlers of
32-bit calls.
We need to make ARM_SMCCC_FAST_CALL unsigned long, so it would work properly
on 32 bit architectures.

Moved out PHY specific code out of Cortina NI Ethernet driver

A few minor changes:
* Get rid of leftover comments, other commits removed the defines they
referred to.
* CONFIG_SYS_NETA_INTERFACE_TYPE is not used anymore since commit
e3b9c98a23ca9 ("net: mvneta: Convert to driver model").
* Drop CONFIG_USB_MAX_CONTROLLER_COUNT: it is per-HCI type, so XHCI and
EHCI could still both work be used.
* Unconditionally define CONFIG_EHCI_IS_TDI: it has no effect on XHCI so
that conditional doesn't make any sense.
* Define a larger PHY_ANEG_TIMEOUT: In my test bed, the NIC is directly
connected to some RTL8111 and the default 8s timeout was often too
short.

H616 is very similar to H6 so most of the infrastructure can be reused.
However, two big differences are that it doesn't have functional SRAM A2
which is usually used for TF-A and it doesn't have ARISC co-processor.
It also needs bigger SPL size - 48 KiB.

It turns out that there are at least 2 other SoCs which have basically
the same memory map, similar clocks and other features as H6. It's very
likely that we'll see more such SoCs in the future. In order to ease
porting to new SoCs and lower ifdef clutter, introduce common symbol for
them.

This patch converts the dart6ul ethernet support to DM_ETH and cleans
up the legacy ethernet code. The clean up, more specifically:
* moves the fec2 node and pin definition to the carrier board DTS
since the phy associated with it is on the carrier board and not on
the SoM;
* add the reset pin associated to each phy;
* separate the ethernet, mdio and reset pins of each fec so that they
are easier to reference;
* add clock properties to the phy nodes since they are connected to the
50Mhz ENET[12]_TX_CLK clock of the SoC;
* remove CONFIG_BOARD_EARLY_INIT_F since the function is now empty.
