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"
The U_BOOT_CMD_COMPLETE() macro has a semicolon at the end, perhaps
inadvertently. Some code has taken advantage of this.
Tidy this up by dropping the semicolon from the macro and adding it to
macro invocations as required.

To quote the author:
The show_board_info() function was adjusted to weak so that it could be
entirely replaced with a board-specific implementation.
The intended way for boards to provide their own information is via a
sysinfo driver. But currently there is no way to show anything other
than the model name.
This series adds support for showing a few more items, in a way that is
easy for boards to extend.
Since there is already a weak checkboard() function, we don't need to
have two levels of weak function here. So this series drops the weak
attribute from show_board_info()
Existing boards will see a slight change in output, in that the model
name will appear first, before any custom output. If that is a problem,
then the solution is to implement a sysinfo driver for the board.
Create a sysinfo driver to avoid needing a custom checkboard()
function. With this the following information is printed when booting
from coreboot under QEMU:
Model: Standard PC (i440FX + PIIX, 1996)
Manufacturer: QEMU

There is a couple of issues related to SYS_CONFIG_NAME config in
axy17lte Kconfig.
1. The global SYS_CONFIG_NAME in axy17lte Kconfig overrides
SYS_CONFIG_NAME for all boards specified after this line in
arch/arm/mach-exynos/Kconfig:
source "board/samsung/axy17lte/Kconfig"
Right now it's the last 'source' line there, so the issue is not
reproducible. But once some board is moved or added after this line
the next build error will happen:
GEN include/autoconf.mk.dep
In file included from ./include/common.h:16:
include/config.h:3:10: fatal error: configs/exynos78x0-common.h.h:
No such file or directory
3 | #include <configs/exynos78x0-common.h.h>
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
compilation terminated.
That's happening because axy17lte Kconfig defines SYS_CONFIG_NAME
option in global namespace (not guarded with any "if TARGET_..."), so
it basically rewrites the correct SYS_CONFIG_NAME defined in the
hypothetical boards which might appear after axy17lte in mach-exynos
Kconfig.
2. Another side of the issue is that SYS_CONFIG_NAME is defined
incorrectly in axy17lte Kconfig:
config SYS_CONFIG_NAME
default "exynos78x0-common.h"
The .h extension should not have been specified there. It's leading
to a build error, as the generated include file has a double '.h'
extension.
3. Each target in axy17lte/Kconfig defines its own SYS_CONFIG_NAME. But
all of those in fact incorrect, as corresponding
include/configs/<CONFIG_SYS_CONFIG_NAME>.h header files don't exist.
4. The global SYS_CONFIG_NAME pretty much repeats the help description
from arch/Kconfig and doc/README.kconfig.
Corresponding defconfig files (a*y17lte_defconfig) fix above issues by
overriding SYS_CONFIG_NAME and correctly setting it to
"exynos78x0-common".
Fix all mentioned issues by removing the incorrect global
SYS_CONFIG_NAME and instead specifying it (correctly) in SYS_CONFIG_NAME
options for each target instead.

Add initial support for STM32MP2 SoCs family.
SoCs information are available here :
https://www.st.com/content/st_com/en/campaigns/microprocessor-stm32mp2.html
Migrate all MP1 related code into stm32mp1/ directory
Create stm32mp2 directory dedicated for STM32MP2 SoCs.
Common code to MP1, MP13 and MP25 is kept into
arch/arm/mach-stm32/mach-stm32mp directory :
- boot_params.c
- bsec
- cmd_stm32key
- cmd_stm32prog
- dram_init.c
- syscon.c
- ecdsa_romapi.c
For STM32MP2, it also :
- adds memory region description needed for ARMv8 MMU.
- enables early data cache before relocation.
During the transition before/after relocation, the MMU, initially setup
at the beginning of DDR, must be setup again at a correct address after
relocation. This is done in enables_caches() by disabling cache, force
arch.tlb_fillptr to NULL which will force the MMU to be setup again but
with a new value for gd->arch.tlb_addr. gd->arch.tlb_addr has been
updated after relocation in arm_reserve_mmu().

To quote Andre:
The first few patches are some easy refactorings and fixes, most of them
actually don't change the generated binaries at all. Then there is a
defconfig for a new board, for which we just gained the .dts file from
the last kernel DT sync.
On top there is support for a new PMIC (AXP313), and LPDDR4 support for
the Allwinner H616 SoC, both of which are needed to support new devices
that appeared lately, especially cheap TV boxes.
While those are technically new features, they don't affect existing
boards, for instance the LPDDR4 support code is guarded by a new DRAM
type Kconfig variable. So the risk for regressions is very slim.
Gitlab CI passed, and I booted that briefly on some boards, including an
H616 and an H618 one (with LPDDR4).
On boards using the AXP313 PMIC, the DRAM rail is often not setup
correctly at reset time, so we have to program the PMIC very early in
the SPL, before running the DRAM initialisation.
Add a simple AXP313 PMIC driver that knows about DCDC2(CPU) and
DCDC3(DRAM), so that we can bump up the voltage before the DRAM init.
