72239fc85f vboot: Add FIT_SIGNATURE_MAX_SIZE protection
This adds a new config value FIT_SIGNATURE_MAX_SIZE, which controls the
max size of a FIT header's totalsize field. The field is checked before
signature checks are applied to protect from reading past the intended
FIT regions.

This field is not part of the vboot signature so it should be sanity
checked. If the field is corrupted then the structure or string region
reads may have unintended behavior, such as reading from device memory.
A default value of 256MB is set and intended to support most max storage
sizes.

8a9dc16e4d spl: Add full fitImage support
Add support for loading U-Boot and optionally FDT from a fitImage
in SPL by using the full fitImage support from U-Boot. While we do
have limited SPL loading support in SPL with a small footprint, it
is missing a lot of important features, like checking signatures.
This support has all the fitImage features, while the footprint is
obviously larger.

90e407ae01 Kconfig: Enlarge default SYS_MALLOC_F_LEN for AM33XX
Since commit 8e14ba7bd5 ("gpio: omap_gpio: Add DM_FLAG_PRE_RELOC
flag") omap GPIO gets bound before relocation.  Unfortunately due to
this, on at least the beaglebone black, the pre-relocation memory pool
gets exhausted before probing the serial port. This then causes u-boot
to panic as CONFIG_REQUIRE_SERIAL_CONSOLE is set...

Resolve this by resizing the default size of the pre-relocation malloc
pool for AM335X platforms.

341c058654 sunxi: move CONFIG_SYS_TEXT_BASE out of defconfigs
Commit 278b90ce78 ("configs: Migrate CONFIG_SYS_TEXT_BASE") made
CONFIG_SYS_TEXT_BASE a proper Kconfig variable, with the consequence
of moving the common definition shared by almost every sunxi board
into 123 individual defconfig files. But the U-Boot start address
for Allwinner boards is a platform decision which has been around for
ages, so defining it in each *board* config file seems a bit over the
top.
Define the standard values (160MB into DRAM for most SoCs, with two
SoC exceptions) if ARCH_SUNXI is selected, and delete the lines from
the individual defconfigs.

089df18bfe lib: move hash CONFIG options to Kconfig
Commit 94e3c8c4fd ("crypto/fsl - Add progressive hashing support
using hardware acceleration.") created entries for CONFIG_SHA1,
CONFIG_SHA256, CONFIG_SHA_HW_ACCEL, and CONFIG_SHA_PROG_HW_ACCEL.
However, no defconfig has migrated to it.  Complete the move by first
adding additional logic to various Kconfig files to select this when
required and then use the moveconfig tool.  In many cases we can select
these because they are required to implement other drivers.  We also
correct how we include the various hashing algorithms in SPL.

This commit was generated as follows (after Kconfig additions):

[1] tools/moveconfig.py -y SHA1 SHA256 SHA_HW_ACCEL
[2] tools/moveconfig.py -y SHA_PROG_HW_ACCEL

Note:
We cannot move SHA_HW_ACCEL and SHA_PROG_HW_ACCEL simultaneously
because there is dependency between them.

Introduce a CONFIG_SPL_FIT_SOURCE and CONFIG_SPL_FIT_GENERATOR symbol,

or, in the second case, a generator tool (script) to create such
a source file. This script gets passed the list of device tree files
from the CONFIG_OF_LIST variable.
A platform or board can define either of those in their defconfig file
to allow an easy building of such an image.

61304dbec3 cmd: add a new command "config" to show .config contents
This feature is inspired by /proc/config.gz of Linux.  In Linux,
if CONFIG_IKCONFIG is enabled, the ".config" file contents are
embedded in the kernel image.  If CONFIG_IKCONFIG_PROC is also
enabled, the ".config" contents are exposed to /proc/config.gz.
Users can do "zcat /proc/config.gz" to check which config options
are enabled on the running kernel image.

The idea is almost the same here; if CONFIG_CMD_CONFIG is enabled,
the ".config" contents are compressed and saved in the U-Boot image,
then printed by the new command "config".

The usage is quite simple.  Enable CONFIG_CMD_CONFIG, then run
 > config
from the command line interface.  The ".config" contents will be
printed on the console.

This feature increases the U-Boot image size by about 4KB (this is
mostly due to the gzip-compressed .config file).  By default, it is
enabled only for Sandbox because we do not care about the memory
footprint on it.  Of course, this feature is architecture agnostic,
so you can enable it on any board if the image size increase is
acceptable for you.

b331cd6204 cmd, disk: convert CONFIG_PARTITION_UUIDS, CMD_PART and CMD_GPT
We convert CONFIG_PARTITION_UUIDS to Kconfig first.  But in order to cleanly
update all of the config files we must also update CMD_PART and CMD_GPT to also
be in Kconfig in order to avoid complex logic elsewhere to update all of the
config files.

70b8bd7d3b odroid-c2: Enable distro boot
Use the generic "distro" boot framework to enable automatic DHCP boot.
MMC and USB are not yet implemented, so this is the only boot option.

The fdt and kernel addresses are adopted from downstream; ramdisk and
scriptaddr addresses were chosen arbitrarily.

266aa86b04 Kconfig: Refactoring of top-level Kconfig file
Some refactoring of the top-level Kconfig file which includes:

* using "if" to remove numerous identical dependency tests
* reordering config entries to group related ones
* spelling and grammar fixes

There should be no functional changes, only aesthetic ones.
