The current mechanism is unnecessarily complex. Simplify the whole mechanism
such that the entire fitImage is signed, IVT is placed at the end, followed
by CSF, and this entire bundle is also authenticated. This makes the signing
scripting far simpler.

We did not add a prototype for spl_mmc_get_uboot_raw_sector to
include/spl.h before, so add and document one now. Correct the incorrect
prototype in board/advantech/imx8mp_rsb3720a1/imx8mp_rsb3720a1.c and
ensure that we have spl.h where we define a non-weak
spl_mmc_get_uboot_raw_sector as well.

Add missing prototype to fix the sparse warning, warning: no
previous prototype for 'board_boot_order' [-Wmissing-prototypes].

The actual function being documented is jump_to_image_optee(), not
jump_to_image_linux().

The rest of the unmigrated CONFIG symbols in the CONFIG_SYS namespace do
not easily transition to Kconfig. In many cases they likely should come
from the device tree instead. Move these out of CONFIG namespace and in
to CFG namespace.

Add a VBE comment which shows the current state. Currently this is just
the phases which booted via VBE.

At present sandbox runs the next phase from discrete executables, so for
example u-boot-tpl runs u-boot-vpl to get to the next phase.

In some cases the phases are all built into a single firmware image, as is
done for real boards. Add support for this to sandbox.

Make it higher priority so that it takes precedence over the existing
method.

At present sandbox only supports jumping to a file, to get to the next
U-Boot phase. We want to support other methods, so update the code to
use an enum for the method. Also use the

Use board_boot_order() to set the order, so we can add more options.
Also add the MMC methods into the BOOT_DEVICE enum so that booting
from MMC can be supported.

At present we use symbols for the u-boot-spl entry, but this is not always
what we want. For example, sandbox actually jumps to a u-boot-spl-elf
entry, since sandbox executables are ELF files.

We already handle this with U-Boot by using the '-any' suffix. Add it for
SPL as well.

The current name is inconsistent with SPL which uses CONFIG_SPL_TEXT_BASE
and this makes it imposible to use CONFIG_VAL().

Rename it to resolve this problem.
