e0dda26c2e bootflow: Rework do_bootflow_menu() slightly
When building this with clang, we get a warning such as:
cmd/bootflow.c:412:27: warning: variable 'bflow' is uninitialized when used here [-Wuninitialized]
        printf("Selected: %s\n", bflow->os_name ? bflow->os_name : bflow->name);
                                 ^~~~~

And a suggestion to just initialize bflow to NULL. This would however
would be ensuring a bad dereference. Instead, looking at the function we
rework things so that when CONFIG_EXPO is not enabled (and so, no UI) we
error early and would never reach this point in the code.  Simplify the
rest slightly as well while at this.

80778f505c ide: Move ide_init() into probing
At present the code does ide_init() as a separate operation, then calls
device_probe() to copy over the information. We can call ide_init() from
probe just as easily.

The only difference is that using 'ide init' twice will do nothing.
However it already fails to copy over the new data in that case, so the
effect is the same. For now, unbind the block devices and remove the IDE
device, which causes the bus to be probed again. Later patches will fix
this up fully, so that all blk_desc data is copied across.

Since ide_reset() is only called from ide_init(), there is no need to init
the ide_dev_desc[] array. This is already done at the end of ide_init() so
drop this code.

The call to uclass_first_device() is now within the probe() function of
the same device, so does nothing. Drop it.

b4fae89c48 fdt: Make fdt addr -q quieter
64597346 "fdt: Add -q option to fdt addr for distro_bootcmd" introduced
the -q option for fdt addr, which sets the current working fdt address
without printing any output.

baf41410 "fdt: Show a message when the working FDT changes" made the
utility function set_working_fdt_addr (in cmd/fdt.c) output a message
on each invocation, even if called via fdt addr -q, in which case its
output is now slightly noisier.

To fix this, split out set_working_fdt_addr into set_working_fdt_addr
plus the static function set_working_fdt_addr_quiet.
set_working_fdt_addr_quiet can be called by "quiet" fdt cmd logic and
set_working_fdt_addr is exported (as before) to other boot logic. The
latter calls the former.

Remove the assertion from the fdt addr test case when calling with the
-q argument.

e2aa078c1c cmd: smccc: Print results in hex instead of dec
Printing return value in HEX instead of DEC. Return values are 64 bit
values which impossible to decode in DEC. For example getting CHIP ID in
dec is quite long.

95d85d0da4 cmd: fdt: Add support for integer arrays in fdt get value with index
Currently any integer array value is set as long up-to-40 character
hexadecimal string into environment variable when extracted from an
FDT using 'fdt get value path prop index', because the support for
handling integer arrays is not implemented, and fdt_value_env_set()
code falls back into the hash handling behavior instead.

Implement this support simply by checking whether user supplied any
index. If index is set and the property length is multiple of four,
then this is an integer array, and the code would extract value at
specified index.

There is a subtle change where default index is set to -1 instead of 0.
This is OK, since the only place which checks for index to be less or
equal zero is the string array handling code in fdt_value_env_set() and
that code would work perfectly well with index -1 too.

c2a5d10780 cmd: fdt: Map address returned from fdt get addr to sysmem
The address returned from 'fdt get addr' command must be mapped
into sysmem, as this is a working FDT. Access to this address
without mapping it would lead to crash e.g. in sandbox.

The following command triggers the crash:
"
./u-boot -Dc 'fdt addr $fdtcontroladdr ; fdt get addr var / compatible ; md $var'
"

22cbd654d3 cmd: fdt: Handle 64bit pointers in fdt get addr
The command assumed 32bit pointers so far, with 64bit pointer the
command would overwrite a piece of stack. Fix it by extending the
array size to cater for 64bit pointer, and use snprintf() to avoid
writing past the end of the array ever again.

3300a60277 cmd: fdt: Align checksign parameter names in help text
The help text references 'addr' as an optional key start address,
but the explanation references the same as 'start', make sure they
both read as 'addr'. Also update the abbreviated 'addr' in the
explanation to 'address'.
