The working FDT is the one which comes from the OS and is fixed up by
U-Boot. When the bootm command runs, it sets up the working FDT to be the
one it is about to pass to the OS, so that fixups can happen.
This seems like an important step, so add a message indicating that the
working FDT has changed. This is shown during the running of the bootm
command.

This command is being introduced with the goal of allowing user-friendly
"generic use case" U-Boot builds to pause until user input under some
situations.
The main use case would be when a boot failure happens, to pause until
the user has had time to acknowledge the current state.
Tested using:
make && ./u-boot -v -T -c 'ut lib lib_test_hush_pause'

Start by elaborating on what some of our constraints tend to be with
image location values, and document where these external constraints
can come from. Provide a new subsection, an example based on the TI
ARMv7 OMAP2PLUS families of chips, that gives sample values and explains
why we use these particular values. This is based on what is in
include/configs/ti_armv7_common.h as of fb3ad9bd923d ("TI: Add, use a
DEFAULT_LINUX_BOOT_ENV environment string") as this contains just the
values referenced in this document now and not some of the further
additions that are less generic.

cp.b is used a lot as a way to load binaries to memory and execute
them, however we may need to integrate this with the efi subsystem to
set it up as a bootdev.
So, introduce a loadm command that will be consistent with the other
loadX commands and will call the efi API's.
ex: loadm $kernel_addr $kernel_addr_r $kernel_size
with this a kernel with CONFIG_EFI_STUB enabled will be loaded and
then subsequently booted with bootefi command.

To quote the author:
The bootflow feature provide a built-in way for U-Boot to automatically
boot an Operating System without custom scripting and other customisation.
This is called 'standard boot' since it provides a standard way for
U-Boot to boot a distro, without scripting.
It introduces the following concepts:
- bootdev - a device which can hold a distro
- bootmeth - a method to scan a bootdev to find bootflows (owned by
U-Boot)
- bootflow - a description of how to boot (owned by the distro)
This series provides an implementation of these, enabled to scan for
bootflows from MMC, USB and Ethernet. It supports the existing distro
boot as well as the EFI loader flow (bootefi/bootmgr). It works
similiarly to the existing script-based approach, but is native to
U-Boot.
With this we can boot on a Raspberry Pi 3 with just one command:
bootflow scan -lb
which means to scan, listing (-l) each bootflow and trying to boot each
one (-b). The final patch shows this.
With a standard way to identify boot devices, booting become easier. It
also should be possible to support U-Boot scripts, for backwards
compatibility only.
...

This adds support for booting entirely from JTAG while using a
hard-coded RCW. With these steps, it is not necessary to program a
"good" RCW using CodeWarrior. The method here can be performed with any
JTAG adapter supported by OpenOCD, including the on-board CMSIS-DAP
(albeit very slowly).
These steps require LS1046A support in OpenOCD, which was added in [1].
