這些都定義在 boards.cfg:

Active  arm   armv7          mx6         freescale       mx6qsabreauto       mx6dlsabreautoandroid
mx6qsabreauto:
IMX_CONFIG=board/freescale/mx6qsabreauto/mx6dl.cfg,
MX6DL,
DEFAULT_FDT_FILE="imx6dl-sabreauto.dtb",
DDR_MB=2048,
ANDROID_SUPPORT

對照一下 sabresd:

Active  arm   armv7          mx6         freescale       mx6sabresd          mx6dlsabresdandroid    
mx6sabresd:
IMX_CONFIG=board/freescale/mx6sabresd/mx6dl_4x_mt41j128.cfg,
MX6DL,
DEFAULT_FDT_FILE="imx6dl-sabresd.dtb",
DDR_MB=1024,
SYS_USE_SPINOR,
ANDROID_SUPPORT

和

Active  arm         armv7          mx6         freescale       mx6sabresd          mx6qsabresdandroid
mx6sabresd:
