[PATCH v2 2/2] topic: Use distro_boot for topic-miami boards
Mike Looijmans
mike.looijmans at topic.nl
Wed Mar 12 16:36:32 CET 2025
Adjust configuration and devicetree so the topic-miami board actually
boots.
Replace the custom scripting and just use distro_boot. Override the
standard zynq routines.
The board attempts to boot from SD card first, and falls back to booting
UBIFS from the QSPI NOR flash.
Signed-off-by: Mike Looijmans <mike.looijmans at topic.nl>

Changes in v2:
Disable CONFIG_BOARD_LATE_INIT which interferes with boot order
