Now that we have the same option for SPL and TPL, simplify the logic for
determining the initial stack.

Note that this changes behaviour as current SPL_STACK is a fallback for
TPL. However, that was likely unintended and can be handled with Kconfig
defaults if needed.

The most common word for features that make a platform work is to use
'HAVE_xxx'. Rename this option to match.

Update the help to use the word 'phase' rather than 'stage', since
that is the current terminology. Also clarify that, absent this setting,
the stack pointer generally comes from the value used by U-Boot proper,
rather than SPL.

Move the option just above TPL_STACK which depends on it.

When one xPL phase wants to jump to the next, the next phase must be
loaded into its required address. This means that the TEXT_BASE for the
two phases must be different and there cannot be any memory overlap
between the code used by the two phases. It also can mean that phases
need to be moved around to accommodate any size growth.

Having two xPL phases in SRAM at the same time can be tricky if SRAM
is limited, which it often is. It would be better if the second phase
could be loaded somewhere else, then decompressed into place over the
top of the first phase.

Introduce a relocating jump for xPL to support this. This selects a
suitable place to load the (typically compressed) next phase, copies
some decompression code out of the first phase, then jumps to this code
to decompress and start the next phase.

This feature makes it much easier to support Verified Boot for Embedded
(VBE) on RK3399 boards, which have 192KB of SRAM.

It is not a parse error to have a default value of "0" for a "hex" type
entry, instead of "0x0".  However, "0" and "0x0" are not treated the
same even by the tools themselves. Correct this by changing the default
value from "0" to "0x0" for all hex type questions that had the
incorrect default. Fix one instance (in two configs) of a default of "0"
being used on a hex question to be "0x0". Remove the cases where a
defconfig had set a value of "0x0" to be used as the default had been
"0".

As implemented in the arch/arm/mach-rockchip/tpl.c file,
the CONFIG_TPL_BANNER_PRINT option will not work
if either of these options is not enabled.

Add dependency constraints to the CONFIG_TPL_BANNER_PRINT option
definition to prevent configuration problems
where option is enabled but do not take effect.

The i.MX8M boards use partially specified binman images which have an
SPL entry without a U-Boot entry. This would normally cause an error due
to the 'u_boot_any' binman symbols declared by BINMAN_UBOOT_SYMBOLS
requiring a U-Boot-like entry in the same image as the SPL.

However, a problem in the ARMv8 __image_copy_start symbol definition
effectively disables binman from attempting to write any symbols at all,
so everything appears to work fine until runtime. A future patch fixes
the issue in the linker scripts, which lets binman fill in the symbols,
which would result in the build error described above.

Explicitly disable the 'u_boot_any' symbols for i.MX8M boards. They are
already effectively unusable, and they are incompatible with the boards'
current binman image descriptions.

Enabling CONFIG_BINMAN makes binman run after a build to package any
images specified in the device-tree. It also enables a mechanism for
SPL/TPL to declare and use special linker symbols that refer to other
entries in the same binman image. A similar feature that gets this info
from the device-tree exists for U-Boot proper, but it is gated behind a
CONFIG_BINMAN_FDT unlike the symbols.

Confusingly, CONFIG_SPL/TPL_BINMAN_SYMBOLS also exist. These configs
don't actually enable/disable the symbols mechanism as one would expect,
but declare some symbols for U-Boot using this mechanism.

Reuse the BINMAN_SYMBOLS configs to make them toggle the symbols
mechanism, and declare symbols for the U-Boot phases in a dependent
BINMAN_UBOOT_SYMBOLS config. Extend it to cover symbols of all phases.
Update the config prompt and help message to make it clearer about this.
Fix binman test binaries to work with CONFIG_IS_ENABLED(BINMAN_SYMBOLS).
