Simon Glass <sjg@chromium.org> says:
When the SPL build-phase was first created it was designed to solve a
particular problem (the need to init SDRAM so that U-Boot proper could
be loaded). It has since expanded to become an important part of U-Boot,
with three phases now present: TPL, VPL and SPL
Due to this history, the term 'SPL' is used to mean both a particular
phase (the one before U-Boot proper) and all the non-proper phases.
This has become confusing.
For a similar reason CONFIG_SPL_BUILD is set to 'y' for all 'SPL'
phases, not just SPL. So code which can only be compiled for actual SPL,
for example, must use something like this:
#if defined(CONFIG_SPL_BUILD) && !defined(CONFIG_TPL_BUILD)
In Makefiles we have similar issues. SPL_ has been used as a variable
which expands to either SPL_ or nothing, to chose between options like
CONFIG_BLK and CONFIG_SPL_BLK. When TPL appeared, a new SPL_TPL variable
was created which expanded to 'SPL_', 'TPL_' or nothing. Later it was
updated to support 'VPL_' as well.
This series starts a change in terminology and usage to resolve the
above issues:
- The word 'xPL' is used instead of 'SPL' to mean a non-proper build
- A new CONFIG_XPL_BUILD define indicates that the current build is an
'xPL' build
- The existing CONFIG_SPL_BUILD is changed to mean SPL; it is not now
defined for TPL and VPL phases
- The existing SPL_ Makefile variable is renamed to SPL_
- The existing SPL_TPL Makefile variable is renamed to PHASE_
It should be noted that xpl_phase() can generally be used instead of
the above CONFIGs without a code-space or run-time penalty.
This series does not attempt to convert all of U-Boot to use this new
terminology but it makes a start. In particular, renaming spl.h and
common/spl seems like a bridge too far at this point.
The series is fully bisectable. It has also been checked to ensure there
are no code-size changes on any commit.
Popup the bootmenu for 5 sec with default boot options to CC on AMD CCs and
default to SOM on others.
Users can anytime disable the bootmenu by setting the variable
enable_bootmenu=0 in zynqmp_kria.env or setup it up at run time and save
variables to NV memory.
The patch is also fixing issue created by commit 4c73630686 ("cmd:
setexpr: fix no matching string in gsub return empty value") which has
changed return value from setexpr command (Before this commit when
matching string wasn't found command return 1 that's why was possible to
use with if).

rather it's using default address for Microblaze platform,

With the introduction of separate config symbols for the SPL phase of
U-Boot, the condition checks need to be tweaked so that platforms that

The current LMB API's for allocating and reserving memory use a
per-caller based memory view. Memory allocated by a caller can then be
overwritten by another caller. Make these allocations and reservations
persistent using the alloced list data structure.
Two alloced lists are declared -- one for the available(free) memory,
and one for the used memory. Once full, the list can then be extended
at runtime.

This series will automatically add /chosen/kaslr-seed to the dt if
DM_RNG is enabled
during the boot process.
If RANDOMIZE_BASE is enabled in the Linux kernel instructing it to
randomize the virtual address at which the kernel image is loaded, it
expects entropy to be provided by the bootloader by populating
/chosen/kaslr-seed with a 64-bit value from source of entropy at boot.
If we have DM_RNG enabled populate this value automatically when
fdt_chosen is called. We skip this if ARMV8_SEC_FIRMWARE_SUPPORT
is enabled as its implementation uses a different source of entropy
that is not yet implemented as DM_RNG. We also skip this if
MEASURED_BOOT is enabled as in that case any modifications to the
dt will cause measured boot to fail (although there are many other
places the dt is altered).
As this fdt node is added elsewhere create a library function and
use it to deduplicate code. We will provide a parameter to overwrite
the node if present.
For our automatic injection, we will use the first rng device and
not overwrite if already present with a non-zero value (which may
have been populated by an earlier boot stage). This way if a board
specific ft_board_setup() function wants to customize this behavior
it can call fdt_kaslrseed with a rng device index of its choosing and
set overwrite true.
Note that the kalsrseed command (CMD_KASLRSEED) is likely pointless now
but left in place in case boot scripts exist that rely on this command
existing and returning success. An informational message is printed to
alert users of this command that it is likely no longer needed.
Note that the Kernel's EFI STUB only relies on EFI_RNG_PROTOCOL for
randomization and completely ignores the kaslr-seed for its own
randomness needs (i.e the randomization of the physical placement of
the kernel). It gets weeded out from the DTB that gets handed over via
efi_install_fdt() as it would also mess up the measured boot DTB TPM
measurements as well.

On Kria when board starts from Image A or Image B partition multiboot
register is already setup to that location. When reset command is called
board is issuing soft reset which start SW at already used location (offset
of multiboot * 32k).
But board should continue to run from multiboot offset 0 (start of QSPI)
and call early bootloader every reboot that's why clear multiboot register
to 0 by default to go that route all the time.

- Add FDT_FIXUP_PARTITIONS support
- Fix legacy format MAC decoding
zynqmp:
- Enable semihosting SPL support
- DT updates

- Update SDIO tristate pin configuration
- Disable SPI_FLASH_BAR to avoid issue with SPI after update
mbv:
- Enable SPL and binman
- Small platform changes
zynqmp-nand:
- Error out in case of unsupported SW ECC
- Clean error path
versal-net:
- Support multiple locations for variables
Private function for finding out location of environment is not working
when ENV_IS_NOWHERE is disabled.
The reason is that current fallback is ENVL_UNKNOWN when
CONFIG_ENV_IS_NOWHERE is not enabled. The code could be updated like this
- return ENVL_NOWHERE;
+ if (IS_ENABLED(CONFIG_ENV_IS_NOWHERE))
+ return ENVL_NOWHERE;
+ return ENVL_UNKNOWN;
But then boot is still not working because ENVL_UNKNOWN has no driver and
env_init() returns -ENODEV. That's why it is better not to define board
specific env_get_location() because then weak env_get_location() is used
which is going over env_locations[] and returning locations which are
actually enabled in u-boot instance.

Generally speaking, we do not prompt for this value and define it in the
board specific Kconfig file. There are some valid use cases however
today where we do prompt for this value, so instead of having this be
done in a number of locations, do this at the top-level location only.
This removes the question from a number of other locations and makes it
consistent that when we do set the value directly, we always do it the
same way. We don't need to specify the type, it's always string.
