Some ARM64 platforms (such as Allwinner A64/H5) have a boot process
where U-Boot encapsulates the BL31 part of the ARM trusted
firmware. For such platforms, we need to build ATF before U-Boot, and
pass a BL31 variable pointing to ATF bl31.bin to the U-Boot build
process.
This commit introduces a BR2_TARGET_UBOOT_NEEDS_ATF_BL31 variable to
achieve this.

cannot be enabled together with ARM_TRUSTED_FIRMWARE_UBOOT_AS_BL33

More and more of our defconfigs need to generate a U-Boot boot
script. It's a simple call to mkimage, but we already have 12
instances of this logic in board/, and there are patch series waiting
in patchwork adding 3 more boards that need this.
So let's add an option in the U-Boot package to generate such a boot
script image easily.
Note that we assume a single script needs to be generated, and the
output file name is boot.scr. The only platform for which it seems to
not be the case are the Boundary Devices platforms: they generate two
boot scripts, 6x_bootscript and 6x_upgrade, but they are anyway
installed inside TARGET_DIR, not BINARIES_DIR.

On older SoCFPGA SoCs, there was not enough SRAM to fit the entire
U-Boot, so a SPL model was used. The SPL was therefore the binary that
had to be "prepared" to be loaded by the ROM code using the mkpimage
tool.
With newer SoCFPGA SoCs, there is enough SRAM to fit the entire U-Boot,
and therefore the ROM code directly loads U-Boot. In this case, it's the
real U-Boot image (not the SPL) that needs to be prepared using
mkpimage.
This code adds support for the newer SoCFPGA SoCs, by adjusting the
mkpimage related logic to apply on the SPL if an SPL is enabled, or on
the full U-Boot image otherwise.

Commit 3e3fef39e7 added new and improved
patch handling, with BR2_TARGET_UBOOT_PATCH. This was in addition to
the existing BR2_TARGET_UBOOT_CUSTOM_PATCH_DIR option, that only
handled directories.
Later, commit 21b25d28fc moved the old
BR2_TARGET_UBOOT_CUSTOM_PATCH_DIR to legacy options. But on the way,
bad things happened:
* The original option was a string, while the one added to Config.in.legacy
is a bool. This results in a warning from defconfigs that actually define
the old BR2_TARGET_UBOOT_CUSTOM_PATCH_DIR (because a string is not a valid
value for a bool), but it does not result in the legacy option being
selected. Consequently, BR2_LEGACY is not selected either.
* The advice at the top of Config.in.legacy to add a hidden WRAP option
to select BR2_LEGACY was not heeded.
* The advice at the top of Config.in.legacy to use the old string
option as the default for the new string option was not heeded. In
this case, the variable was not just renamed, as the old option
supported directories only, while the new one supports files too.
But since the old option is a subset of the new option, it can still
be used to set a useful default.
So, this mod turns the legacy option back to a string, adds a hidden
bool WRAP option to set BR2_LEGACY when the string is non emoty, and
uses the legacy option to set the default for the new option.

Some U-Boot board configurations have CONFIG_FIT_SIGNATURE=y. In this
case, when U-Boot builds its tools, it requires OpenSSL support on the
host system.
Since we clearly don't want to unconditionally depend on host-openssl,
we introduce a new option to explicitly enable the dependency on
host-openssl. This is exactly identical to the existing
BR2_TARGET_UBOOT_NEEDS_DTC, for the dependency on host-dtc. It is
therefore the responsibility of the user to enable this option if his
board configuration uses CONFIG_FIT_SIGNATURE=y.
Necessary to fix bug #9316.

Some U-Boot configurations require the Device Tree compiler to be
available, so we need to depend on host-dtc (example configuration:
zynq_zed).
However, we don't want to build it unconditionally, since the vast
majority of U-Boot configurations don't need it (and host-dtc itself
has a bunch of dependencies).
So, we simply add a Config.in option that allows users to indicate
whether their U-Boot needs DTC or not, and depend on host-dtc if this
option is enabled.

This commit integrates generation of a bootable image
for Xilinx Zynq. The generation is independent on Xilinx
flow and utilizes the host-zynq-boot-bin package. The only
required step is to generate a proper U-Boot SPL (instead
of the FSBL).
The SPL generation might work when providing the working
ps7_init.c file to U-Boot. However, from U-Boot 2015.07
a set of generic ps7_init.c files is included and used to
build the U-Boot SPL for various boards. The ps7_init.c file
has been released under GNU/GPL license for this purpose.
For details, see

Allow to generate 'u-boot.nand', Freescale i.MX28 BootStream format (.sb)
with a header for booting from NAND flash.
There are two possibilities when preparing an image writable to NAND flash:
1) The NAND was not written at all yet or the BCB (Boot Control Blocks) is
broken. In this case, the NAND image 'u-boot.nand' needs to written.
2) The NAND flash was already written with a good BCB. This applies after
'u-boot.nand' was correctly written. There is no need to write the BCB
again. In this case, the bootloader can be upgraded by writing 'u-boot.sb'.
To satisfy both cases 'u-boot.nand' as well as the make target 'u-boot.sb' are
copied to the binaries directory.
mxsboot for NAND images needs all three parameters typed in as integer values
(hex values do not work). The default values choosen are typical sizes for a
NAND flash.
