# select_de25_profile.sh — pick the DE25-Nano board build profile WITHOUT hand-editing
# the QSF. Rewrites the two managed marker blocks in the board QSF:
#     # >>> DE25_PROFILE_FIXTURE >>> ... # <<< DE25_PROFILE_FIXTURE <<<
#     # >>> DE25_PROFILE_SCENE   >>> ... # <<< DE25_PROFILE_SCENE   <<<
# Everything else in the QSF (EMIF macros GS_LPDDR4B_FB/GS_LPDDR_FB, pin/IP assignments)
# is profile-independent and untouched. After switching, re-fit in Quartus as usual.
#
# Usage:
#   ./scripts/select_de25_profile.sh lpddr_tex          # Ch322 LPDDR-backed texture demo (tritex)
#   ./scripts/select_de25_profile.sh lpddr128_scanout   # Ch321 128x128 LPDDR framebuffer scanout
#   ./scripts/select_de25_profile.sh --list             # list profiles + show the active one
#
# Add a profile by extending the case blocks below (fixture mems + scene VERILOG_MACROs).
