In OP-TEE, the "optee_core@" node is reserved, appended in non secure
device tree (see mark_tzdram_as_reserved() function under CFG_DT) so
this name must be checked in optee_get_reserved_memory().
We keep the check on /reserved-memory/optee@ node to have backward
compatibility with STMT32Image booting, when the reserved node is
already present in U-Boot or SPL device tree with name "optee@".
This patch solves a boot issue on board with OP-TEE for U-Boot
compiled with stm32mp15_defconfig and without secure configuration
device tree (stm32mp157c-dk2.dts for example).

Move the stm32mp1 data cache reconfiguration after the lmb init call
board_r::initr_lmb to allow parsing of the reserved region with
no-map tag.
After this patch the DDR is not fully mapped up to arch_early_init_r()
call, only the relocation region is mapped, but it is enough for
the first board_r initialization phases; later, when arch_early_init_r()
is called, the LMB is already initialized and the function
lmb_is_reserved_flags() function is functional, this LMB function
is called in the weak function dram_bank_mmu_setup() when
dcache_enable() is executed.
Without this change, as LMB is not initialized when it is used in
dram_bank_mmu_setup, the OP-TEE region is mapped cache-able by U-Boot
and we have some firewall violation since "LMB memory map global and
persistent" series.

Reserved memory for OP-TEE is located at end of DDR for STM32MP1 SoC only
(STM32MP13 and STM32MP15) and the OP-TEE reserved memory is located at the
beginning of DDR for STM32MP25 SoC, before CONFIG_TEXT_BASE and
with reserved memory for companion coprocessor. So the ram_top is limited
by OP-TEE reserved memory only for STM32MP1 SoC.
This patch solves an issue for ram_top value on STM32MP25 SoC because the
generic reserved memory management, based on LMB, is no more used before
relocation.

Describe the u-boot.its generation in stm32mp15xx-dhsom-u-boot.dtsi
binman {} DT node as a replacement for current CONFIG_SPL_FIT_SOURCE
use, dispose of both u-boot-dhcom.its and u-boot-dhcor.its.
Use fdt-SEQ/config-SEQ to generate a list of fdt-N fitImage images {} and
matching configuration {} node entries. The configuration node entry names
no longer encode _somrevN_boardrevN suffix, which was never really used, so
drop this functionality by default. Rework board_fit_config_name_match() to
match on the new configuration node entry names.
Users who do need the match on _somrevN_boardrevN can either replace the
fdt-SEQ/config-SEQ with fixed fdt-N/config-N nodes which each encode the
matching 'description = "NAME_somrevN_boardrevN"' to restore the old

Sughosh Ganu <sughosh.ganu@linaro.org> says:
This is part two of the series to have the EFI and LMB modules have a
coherent view of memory. Part one of this goal was to change the LMB
module to have a global and persistent memory map. Those patches have
now been applied to the next branch.
These patches are changing the EFI memory allocation API's such that
they rely on the LMB module to allocate RAM memory. This fixes the
current scenario where the EFI memory module has no visibility of the
allocations/reservations made by the LMB module. One thing to note
here is that this is limited to the RAM memory region, i.e. the
EFI_CONVENTIONAL_MEMORY type. Any other memory type that is to be
added to the EFI memory map, still gets handled by the EFI memory
module.
Changes since V3:
* Add comments for the LMB_NOOVERWRITE and LMB_NONOTIFY flags
* Drop use of is_addr_in_ram() function
* Drop use of CONFIG_MEM_MAP_UPDATE_NOTIFY symbol to check if the
notification needs to be sent.
* s/lmb_notify/lmb_should_notify
* Put a check for EFI_LOADER in the lmb_should_notify() function
Some test logs to highlight the issue that is being fixed by the series.

We have added a "set" sub command to bootmeth, add some tests to check
it's operation.

We have previously added logic to allow a "fallback" option to be
specified in the extlinux configuration. Provide a command that allows
us to set this as the preferred default option when booting.
Combined with the bootcount functionality, this allows the "altbootcmd"
to provide a means of falling back to a previously known good state
after a failed update. For example, if "bootcmd" is set to:
bootflow scan -lb
We would set "altbootcmd" to:
bootmeth set extlinux fallback 1; bootflow scan -lb
Causing the boot process to boot from the fallback option.

The "fallback" extlinux config option allows us to set an alternative
default boot option for when it has been detected that the default is
failing. Implement the logic required to boot from this option when
desired.

When the connection to a board dies, assume it is dead forever until
some user action is taken. Skip all remaining tests. This avoids CI
runs taking an hour, with hundreds of 30-second timeouts all to no
avail.

When configured correctly, we can detect when boot fails after the boot
process has been handed over to the kernel through the use of U-Boot's
bootcount support. In some instances, such as when we are performing
atomic updates via a system such as OSTree, it is desirable to provide a
fallback option so that we can return to a previous (hopefully working)
state.
Add a "fallback" option to the supported extlinux configuration options
that points to a label like "default" so that we can utilise this in
later commits.

The tests currently catch a very broad Exception in each case. This is
thrown even in the event of a coding error.
We want to handle exceptions differently depending on their severity,
so that we can avoid hour-long delays waiting for a board that is
clearly broken.
As a first step, create some new exception types, separating out those
which are simply an unexpected result from executed a command, from
those which indicate some kind of hardware failure.

There is quite a bit of code to deal with receiving data from the target
so move it into its own receive() function.

The settings are decoded in two places. Combine them into a new

When a test returns -EAGAIN this should not be considered a failure.
Fix what seems to be a problem case, where the pytests see a failure
when a test has merely been skipped.
We cannot squash the -EAGAIN error in ut_run_test() since the failure
count is incremented by its caller, ut_run_test_live_flat()
The specific example here is on snow, where a test is compiled into the
image but cannot run, so returns -EAGAIN to skip:
test/py/tests/test_ut.py sssnow # ut bdinfo bdinfo_test_eth
Test: bdinfo_test_eth: bdinfo.c
Skipping: Console recording disabled
test/test-main.c:486, ut_run_test_live_flat(): 0 == ut_run_test(uts,
test, test->name): Expected 0x0 (0), got 0xfffffff5 (-11)
Test bdinfo_test_eth failed 1 times
Skipped: 1, Failures: 1
snow # F+u-boot-test-reset snow snow
The fix is simply to respect the return code from ut_run_test(), so do
that.
