board: siemens: iot2050: Pass DDR size from FSBL

2024-10-29T02:54:23+00:00

Due to new DDR size introduction, the current logic of determining the
DDR size is not able to get the correct size.

Instead, the DDR size is determined by the FSBL(SEBOOT) then passed to
u-boot through the scratchpad info.

The SEBoot version must be >= D/V01.04.01.02 to support this change.

Also now for some variants, the DDR size may > 2GB, so borrow some code
from the TI evm to iot2050 to support more than 2GB DDR.

board: siemens: iot2050: Fix mistake in list of writable env vars

2024-10-29T02:54:23+00:00

This prevented to set m2_manual_config - as evaluated by
m2_connector_setup - under strict configurations for secure boot.

iot2050: Allow for more than 1 USB storage device

2023-10-28T13:18:19+00:00

This was lost in refactoring while some users of the IOT2050 expect it
to work: Make sure that up to 3 USB storage devices are probed.

boards: siemens: iot2050: Fix boot configuration

2023-07-28T14:11:00+00:00

The common env bits now come via ti_armv7_common.env, include it.
Furthermore restore the board-specific boot targets and their ordering
that is now enforced k3-wide differently. Finally, enable
CONFIG_LEGACY_IMAGE_FORMAT explicitly which got lost while turning
FIT_SIGNATURE on by default for k3 devices.

Since K3 devices are moving towards distroboot, remove duplicates and
add it in common file to import from.

iot2050: Add support for configuring M.2 connector

2023-03-29T15:58:26+00:00

The M.2 slots of the related IOT2050 variant need to be configured
according to the plugged cards. This tries to detect the card using the
M.2 configuration pins of the B-key slot. If that fails, a U-Boot
environment variable can be set to configure manually. This variable is
write-permitted also in secure boot mode as it is not able to undermine
the integrity of the booted system.

The configuration is then applied to mux the serdes and to fix up the
device tree passed to or loaded by the bootloader. The fix-ups are
coming from device tree overlays that are embedded into the firmware
image and there also integrity protected. The OS remains free to load
a device tree to which they do not apply: U-Boot will not fail to boot
in that case.

Based on original patch by Chao Zeng.

iot2050: Add CFG_ENV_FLAGS_LIST_STATIC

2023-03-29T15:58:26+00:00

Will be needed when CONFIG_ENV_WRITEABLE_LIST is enabled. The listed
variables shall remain writable, for informational purposes - they have
to be considered untrusted because the persistent U-Boot env is not
protected.
