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"
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.

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.

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.

At this point, the remaining places where we have a symbol that is
defined as CONFIG_... are in fairly odd locations. While as much dead
code has been removed as possible, some of these locations are simply
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
a rename of all such remaining symbols to be CFG_... rather than
CONFIG_...

This converts the following to Kconfig:

CONFIG_HOSTNAME
CONFIG_IPADDR
CONFIG_NETMASK
CONFIG_ROOTPATH
CONFIG_SERVERIP
CONFIG_UBOOTPATH
To do this, we introduce a CONFIG_USE_ form of each of the above and
change include/env_default.h to test for that to be set before setting a
value. Further, we don't want to stringify the IP address related values
as they are now properly strings via Kconfig.

- 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.
