# A fixed size forces vendor.img to always equal exactly that value byte for
# byte -- this AOSP branch's build_image.py never shrinks a fixed-size ext4
# image to its actual content. With BOARD_USES_FULL_RECOVERY_IMAGE := true,
# AOSP's assert-max-image-size then checks vendor.img + recovery.img
# (mkbootimg.mk's fixed 128M FAT container) together against that same fixed
# ceiling, making "vendor.img + recovery.img <= ceiling" mathematically
# impossible at ANY fixed value (X + 128M <= X has no solution). Dynamic
# sizing plus the reserved size below (128M for recovery.img + 64M slack)
# gives vendor.img real headroom instead of an unsatisfiable assertion.
# On-flash vendor partition size in mkimg.sh is unaffected -- ext4 doesn't
# need to fill its containing partition, so mkimg.sh's fixed VENDOR_SIZE
# constant stays valid as the physical partition ceiling either way.
