[PATCH 4/6] siemens: board: clean up draco products vs common
Enrico Leto
enrico.leto at siemens.com
Tue Nov 21 15:21:32 CET 2023
The common folder was initialially created for the common parts of the
products based on draco-am355x board family. These are the product
lines 'pxm2', 'rut' and the base line named 'draco'!
Adding the new capricorn-imx8 board family, common was enhanced without
cleanup.
Move all am355x specifics to a new file 'board_am335x'.
