# Board target table — T= selects board, sets ARCH + BOARD + BOARD_NAME.
# Included early by both Makefile and Makefile.starkernel, before arch
# normalization runs. Each Makefile applies board-specific flag overrides
# after its own arch block.
#
# Adding a new board: add an ifeq block here, then add compiler-flag
# overrides in the board-override sections of Makefile and
# Makefile.starkernel if the board needs tuning beyond the arch default.
