This is the baseline support for the SIMATIC IOT2050 devices.
Changes in v8: - rebased - added support for product generation 2 board - align device trees with upstream [pending] kernel version - only warn on missing watchdog firmware binary - removed bits only needed for incomplete prueth support
Changes in v7: - rebased - registered board doc with index
Changes in v6: - rebased - converted board README to docs/board/siemens/iot2050.rst
Changes in v5: - rebased - use DEFAULT_LINUX_BOOT_ENV from ti_armv7_common.h, rather than home-grown values - avoids misaligned kernel load address - no longer exposes issue around LMB reservations
Changes in v4: - rebased - make rtd-wdt firmware a "loadable" inside U-Boot proper fit image, avoiding controversial embedding as object - improved mmc1 removal from boot_targets - fixed various build issues
Changes in v3: - rebased - addressed several checkpatch warnings - a few #ifdef -> IS_ENABLED conversions - comment marker for SPDK identifier in .S file - trailing whitespaces - factored out rti_wdt_load_fw (less #ifdef)
Changes in v2: - rebased - sync with upstream-accepted DT - add boot switch - include watchdog support
Allows to boot mainline kernels and the BSP-derived kernel we currently ship as reference.
Note that this baseline support lacks Ethernet drivers. We are working closely with TI to ensure that the to-be-upstreamed icssg-prueth driver will work both with new SR2.0 AM65x silicon as well as with SR1.0 which is used in the currently shipped IOT2050 devices.
A staging tree for complete IOT2050 support can be found at [1]. Full image integration is available via [2].
