Currently the U-Boot project contains 2 documentation directories:
- doc/
- Documentation/
The Documentation directory only contains device tree bindings related
content, so move the 3 files to doc/device-tree-bindings/.

1. Since libavb library alone is highly portable, introduce dedicated
Kconfig symbol for AVB bootloader-dependent operations, so it's possible
to build libavb separately. AVB bootloader-dependent operations include:
* Helpers to process strings in order to build OS bootargs.
* Helpers to access MMC, similar to drivers/fastboot/fb_mmc.c.
* Helpers to alloc/init/free avb ops.
2. Add CONFIG_FASTBOOT dependency, as fastboot buffer is
re-used in partition verification operations.

The Linux kernel moved to sphinx-based documentation and got rid of the
DocBook based documentation quite a while ago. Hence, the DocBook
documentation for U-Boot should be converted as well.
To achieve this, import the necessary files from Linux v4.17, and
convert the current DocBook documentation (three files altogether) to
sphinx/reStructuredText.
For now, all old DocBook documentation was merged into a single
handbook, tentatively named "U-Boot Hacker Manual".
For some source files, the documentation style was changed to comply
with kernel-doc; no functional changes were applied.

To let the full U-Boot know where it was booted from (i.e. which of

image), we define (and document) /chosen/u-boot,spl-boot-device as the
property that could/should automatically be injected by SPL.
This commit only contains a documentation change, which documents the
new property and the intended usage.

This allows memory information to be provided in the device tree,
rather than hard-coded in, which will make it simpler to handle
similar devices with different memory banks, as the board-id values
or masks can be used to match devices.

At present the EFI application and payload support codes in the x86
directory is distributed in a hybrid way. For example, the Kconfig
options for both app and payload are in arch/x86/lib/efi/Kconfig,

CONFIG_EFI_STUB.
This refactors the codes by consolidating all the EFI support codes

on Intel Cougar Canyon 2 board, called SPI-0 and SPI-1 respectively.
SPI-0 stores the flash descriptor and the ME firmware. SPI-1 stores

both ME firmware and U-Boot does not make sense.

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.
In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.
This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

Related to the target part, we cannot use arm-none-eabi as that ends up
being too generic of an ARM target for things like say rpi_3_32b to
