9565771076 Merge patch series "bootm: Refactoring to reduce reliance on CMDLINE (part A)"
To quote the author:

It would be useful to be able to boot an OS when CONFIG_CMDLINE is
disabled. This could allow reduced code size.

Standard boot provides a way to handle programmatic boot, without
scripts, so such a feature is possible. The main impediment is the
inability to use the booting features of U-Boot without a command line.
So the solution is to avoid passing command arguments and the like to
code in boot/

A similar process has taken place with filesystems, for example, where
we have (somewhat) separate Kconfig options for the filesystem commands
and the filesystems themselves.

This series starts the process of refactoring the bootm logic so that
it can be called from standard boot without using the command line.
Mostly it removes the use of argc, argv and cmdtbl from the internal
logic.

Some limited tidy-up is included, but this is kept to smaller patches,
rather than trying to remove all #ifdefs etc. Some function comments
are added, however.

A simple programmatic boot is provided as a starting point.

This work will likely take many series, so this is just the start.

Size growth with this series for firefly-rk3288 (Thumb2) is:

       arm: (for 1/1 boards) all +23.0 rodata -49.0 text +72.0

This should be removed by:

   https://source.denx.de/u-boot/custodians/u-boot-dm/-/issues/11

but it is not included in this series as it is already large enough.

No functional change is intended in this series.

Changes in v3:
- Add a panic if programmatic boot fails
- Drop RFC tag

Changes in v2:
- Add new patch to adjust position of unmap_sysmem() in boot_get_kernel()
- Add new patch to obtain command arguments
- Fix 'boot_find_os' typo
- Pass in the command name
- Use the command table to provide the command name, instead of "bootm"

1d38722e01 README: Correct docs for CONFIG_SPL_BUILD
This option is defined in both SPL and TPL builds, so correct the docs
related to this. Also point to spl_phase() which is normally a better
option. Mention VPL as well.

a12b36434d README: remove Minicom comment
The main README file is the wrong place to document how different terminal
emulations can be used to access the U-Boot serial console. C-Kermit which
requires a configuration file or several commands to access the U-Boot
console may not be the preferred choice for newcomers. The provided wiki
link is invalid.

The man-pages for loadb and loads already show how to use the commands with
picocom.

41a29f284c cmd: Add a SEAMA image load command
Add a command to load SEAMA (Seattle Image), a NAND flash
on-flash storage format.

This type of flash image is found in some D-Link routers such
as DIR-645, DIR-842, DIR-859, DIR-860L, DIR-885L, DIR890L and
DCH-M225, as well as in WD and NEC routers on the ath79
(MIPS), Broadcom BCM53xx, and RAMIPS platforms.

This U-Boot command will read and decode a SEAMA image from
raw NAND flash on any platform. As it is always using big endian
format for the data decoding is always necessary on platforms
such as ARM.

The command is needed to read a SEAMA-encoded boot image on the
D-Link DIR-890L router for boot from NAND flash in an upcoming
port of U-Boot to the Broadcom Northstar (BCM4709, BCM53xx)
architecture.

A basic test and documentation is added as well. The test must
be run on a target with NAND flash support and at least one
resident SEAMA image in flash.

defined as CONFIG_... are in fairly odd locations. While as much dead

less obvious at first. In other cases, this code is used, but was
defined in such a way as to have been missed by earlier checks.  Perform

6bd2372094 env: Rework ENV_IS_EMBEDDED and related logic slightly
- Drop CONFIG_BUILD_ENVCRC as this is never set directly but instead
  means ENV_IS_EMBEDDED, so reference that in code and rename the Makefile
  usage to BUILD_ENVCRC.
- Remove extra-$(CONFIG_ENV_IS_EMBEDDED) line as it could never be true,
  and likely why there is an extra- line for CONFIG_ENV_IS_IN_FLASH (the
  only use case today of embedded environments).
- With these slight changes we can then see that using the calculated
  symbol of ENV_IS_EMBEDDED is the right thing to use in any code which
  needs to know this situation and can remove CONFIG_ENV_IS_EMBEDDED
  entirely.
